They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don't have the bandwidth. We use lower power to extend tube life, and bandwidth to give you slam. Transformers are the most expensive components in an amplifier but again PrimaLuna doesn't cut corners. PrimaLuna output transformers are custom-designed, wound in-house, and massive. Our DiaLogue Class components feature the largest, widest-bandwidth output transformers we’ve ever made. One reason why no other brand sounds like a PrimaLuna. \"The flat tops and bottoms of these squarewaves correlate with the amplifier's extended low-frequency response; PrimaLuna's output transformers are of excellent quality.\" -John Atkinson, Stereophile Magazine\u003cbr\u003e\u003cbr\u003e\n\nADAPTIVE AUTOBIAS\u003cbr\u003e\n\nPrimaLuna's Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time. More important, it is the ONLY circuit of its kind that is truly \"adaptive\" by addressing \"tube pinch off\" at higher volumes, therefore reducing distortion by over 50% and greatly extending tube life. Adaptive AutoBias is completely passive and NOT in the signal path. The result is low to no maintenance, long tube life, and the lowest possible distortion for amazing sound.\n\u003cbr\u003e\u003cbr\u003e\nPOINT TO POINT WIRING\u003cbr\u003e\n\nYou spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.\u003cbr\u003e\u003cbr\u003e\n\nNO INTERNAL DAC \/ NO INTERNAL PHONOSTAGE\u003cbr\u003e\n\nNever buy an integrated amp with an internal DAC. Why? Because digital changes, and history shows that integrated amps with “old” digital become unwanted and have almost no resale value.\u003cbr\u003e\u003cbr\u003e\n\nBuilt in phonostages are “throw in” and are rarely good quality because manufacturers assume 90% of buyers won’t use them. The external phonostage market is very competitive. You can get something much better for as little as $200, and buy one that actually meets your cartridges needs and YOUR budget.\u003cbr\u003e\u003cbr\u003e\n\nSMARTWATTS - EXTENDED TUBE LIFE\u003cbr\u003e\n\nTube life is simply a matter of how hard you run the tubes. That’s it. The only way to extend tube life is to run them as close to zero as you possible can, making sure it is not so low you go into crossover distortion. The life of a tube will depend on two things: Plate and screen voltage.\u003cbr\u003ev\n\nIf the plate and screen voltage is high, you are more likely to get tube shorts when you turn the amp on and you get cathode stripping which greatly effects the cathodes ability to spit out electrons. We proudly tell you our tubes run at just about 417 volts for the plates and screens.\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna runs their output tubes at a minimum dissipation without going into crossover distortion. When you look at our amps, they provide less power from each tube. With KT-120’s as an example, a PrimaLuna will give you only 21 watts per tube. So running a pair of them you get 42 watts. That’s a lot of power, but the demands per tube are fractional. To get more power the right way is expensive. It requires bigger transformers, sockets, wiring, resistors, capacitors, and the tubes to do it. Which is exactly what PrimaLuna did. But we didn’t stop there.\u003cbr\u003e\u003cbr\u003e\n\nRead this carefully: Power has nothing to do with sound quality. Or bass slam. You can buy a 200 watt receiver for £299, and it will even have surround sound. Do you think for a minute it will sound better than a 50 or 100 watts high end amp costing £10,000? Of course not.

That's why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1\/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever. They are massive, resulting in a preamp weighing a substantial 31 pounds.\u003cbr\u003e\u003cbr\u003e\n\nTUBE RECTIFIED\u003cbr\u003e\n\nIn the world of preamps, experts agree that tube rectification is the gold standard. It’s quieter than solid state rectification, dropping the noise floor. And it offers the most natural, textured, and vibrant presentation because the circuit is now pure tube. But because it is expensive to implement, you’ll only find it in the top of the line models typically costing  $10,000 or more. Finding a preamp using one rectifier tube is sweet. PrimaLuna goes even further using two 5AR4 rectifier tubes in a dual-mono design to present your music with a three-dimensionality that will give you goosebumps.\u003cbr\u003e\u003cbr\u003e\n\nJAPANESE ALPS BLUE VELVET POTENTIOMETER\u003cbr\u003e\n\nThe best tube preamps use analogue volume controls. Not volume control chips. Look inside the most well-known brand of tube preamps and you will see a chip called a DS1666-10 Digital Resistor IC. At Primaluna, we understand the temptation to use this chip as they cost $4 each (half that in quantity!). The preamp will sound fine and be quiet, but true to “chips” it will add an electronic “sheen” to the sound. PrimaLuna prefers analogue. And we use the Gold Standard in motorized potentiometers:  The iconic Alps Blue Velvet. Why? Because they track perfectly, stay quiet, and don’t sound like chips!\u003cbr\u003e\u003cbr\u003e\n\nSUPERQUIET LINE INPUTS\u003cbr\u003e\n\nInput selector switches leak noise and signals from other sources, as they never turn off the other inputs completely. And, they deteriorate with age, requiring the use of cleaners. Many are mounted on the front panel requiring long runs of wires to the back panel inputs. These wires pick up stray noise from RF and EMI.\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.\u003cbr\u003e\u003cbr\u003e\n\nPOINT TO POINT WIRING\u003cbr\u003e\n\nYou spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.\u003cbr\u003e\u003cbr\u003e\n\nDUAL-MONO DESIGN\u003cbr\u003e\n\nExpensive and exotic preamps always use a dual-mono design to achieve a level of imaging not possible otherwise. Most manufacturers don’t employ dual-mono because of expense. It requires two power transformers, double regulation circuits, and in fact….everything is double. In effect, dual-mono means building two discrete and separate preamps into one box. It is so expensive to build, it’s a rarity even at the highest price points. All PrimaLuna preamps are dual-mono for the ultimate in stereo imaging and a sense of space that goes on forever.\u003cbr\u003e\u003cbr\u003e\n\nSMARTGAIN DESIGN\u003cbr\u003e\n\nA preamplifier is typically not required to add any gain to your system when you are using it. It is usually lowering gain from the source you are listening to. The number one complaint from audiophiles about preamp performance is noise. So why is it that so many manufacturers design preamps with 20 to 27dB of gain? And you wonder why there is \"hiss\", and why tubes go noisy or microphonic? PrimaLuna preamps use SmartGain. With a gain specification of only 10.8dB, you will find your PrimaLuna preamp is as quiet as a church mouse. If tubes are less than perfect, you may never know it because they are not amplifying as \"loud\".

While it is fine to use a single tube as a buffer for both channels and claim your DAC is \"tube\", it can't be compared to the PrimaLuna design and what it does for the music.\u003cbr\u003e\u003cbr\u003e\n\nVACUUM TUBE RECTIFIED\u003cbr\u003e\n\nVacuum tube rectified power supply incorporates eleven separate power supply regulation circuits. Tube rectification is synonymous with organic sound, especially when compared to DACs being known as sounding like \"a computer\".\u003cbr\u003e\u003cbr\u003e\n\nUSB DIGITAL INPUT\u003cbr\u003e\n\nUSB digital input allows using your computer for storage and playback of your music with all the benefits of features like playlists and easier access to your whole music library. Rather than just add in an USB input as an afterthought, PrimaLuna engineers searched endlessly looking for the best-sounding USB interface they could find. Their USB input converts the jitter-filled USB digital signal to S\/PDIF, dramatically improving the digital signal quality before it gets to the SuperTubeClock. This USB input is a true high-resolution digital input.\u003cbr\u003e\u003cbr\u003e\n\nThe SuperTubeClock™\u003cbr\u003e\n\nThis is where the magic happens... the SuperTubeClock™ replaces the solid state oscillator normally found in a DAC with a mini triode vacuum tube. By using a tube, PrimaLuna have significantly lowered the amount of jitter and noise, resulting in superior detail retrieval. This in turn yields superior detail and dynamics from top to bottom, and improved overall musicality.\u003cbr\u003e\u003cbr\u003e\n\nFirst a note on the tube itself: The tube is a very rugged, long-life Russian military Triode specifically designed for oscillation purposes... which is its function here. It is running very conservatively so life expectancy is roughly 5 to 10 years of operating time. The small glass envelope guarantees very low microphonics.\u003cbr\u003e\u003cbr\u003e\n\nTriode tubes are inherently low noise devices, and extremely linear when used properly. This means that the oscillation frequency wave it produces is very pure and clean. The noise in the sidebands, from 10Hz to 100kHz on either side of the oscillation frequency, is extremely low. This is the important spectrum for audio. Everything below and beyond that can be ignored.\u003cbr\u003e\u003cbr\u003e\n\nWhen you reclock the inputs, any noise that is generated here appears unfiltered and unattenuated at the input of the conversion chip, and injects jitter, which from then on is an indistinguishable part of the digital audio stream. No amount of cleaning will ever be able to remove this noise once it reaches this point; it has become part of the audio signal. This noise \"rides\" on the audio signal, so you do not hear it as noise, but as smearing of notes and masking of detail. There is a distinctive loss of dynamics, tonal purity, inter-transient silence, and sense of timing. We call this \"noise modulation.\"\u003cbr\u003e\u003cbr\u003e\n\nThis is why the low noise, especially in the 10Hz-100kHz sidebands of the oscillator, is so crucial. Again: below and beyond these frequency extremes is trivial, because it will not affect the audio, and will not reach the analog outputs.\u003cbr\u003e\u003cbr\u003e\n\nWhen the clock is used to clock the DAC chip, a similar situation occurs as described above: the noise appears at the location where the digital audio stream is converted to successive steps in a staircase wave, which represents the analog audio signal. Each step has to be EXACTLY 1\/441000th, 1\/96000th, 1\/176400th, or 1\/192000th. The injected noise introduces a deviation in time which is the exact replica of that noise. This means that the audio signal at the outputs of the DAC chip has the noise riding on it, again as an inherent part of the signal. No amount of filtering will remove the noise once it reaches this step. Again we experience that smear and detail masking, with that distinctive loss of dynamics, tonal purity, inter-transient silence, and sense of timing. Here you see how much sense it makes to reclock BOTH the inputs AND the DAC chip.\u003cbr\u003e\u003cbr\u003e\n\nThe oscillation frequency wave a tube produces is a sine wave. That's no good: It has to be converted to a square wave. This is a very delicate procedure: when the rising and falling edges of a square wave are not steep enough, there exists a certain window during which the actual transition of the data bit is not exactly time-defined. It leaves room to be either too late or too early. This is a partly random process, and partly dependent on surrounding conditions; such as power supply voltage variations, ground noise, inherent CMOS or chip crosstalk in the decoder or DAC chip, etc. All these timing variations are noise, and are called jitter from various sources. The steeper the edges, the more exactly defined the transition moment will be, resulting in less noise (jitter). When a clock produces a very stable frequency with such low jitter, there will be a more accurate reproduction of the original analog waveform of the music.\u003cbr\u003e\u003cbr\u003e\n\nEach square wave seen is measured on a Philips PM3295A analog 400MHz oscilloscope using LeCroy 10:1 probes. These probes attenuate the signal by a factor of 10, in order to not load the device under test with any load, resistive or capacitive. So the vertical resolution on the scope image has to be multiplied by 10. For instance when you see ~0.1V, then it is in reality measuring ~1V(AC).\u003cbr\u003e\u003cbr\u003e\n\nThe SuperTubeClock™ generating a square wave at 8.4672mHz. The vertical slope is measured at ~500mV (each black horizontal line represents 500mV counting from top to bottom). The vertical peak-to-peak travel of the square wave at this frequency is 3.5 Volts, which is excellent.\u003cbr\u003ev\n\nEach black vertical line going from left to right represents 10 nanoseconds. The faster a clock can go from peak to peak, the better.\u003cbr\u003e\u003cbr\u003e\n\nSquare waves present themselves more and more like sine waves the higher you go in frequency. So an 8.4672mHz wave like the one above is still identifiable as a square wave, but as we approach 42.2mHz, typically a square wave will be almost fully rounded off and appear as a sine wave. As a square wave begins to round off, it means the timing of the digital transmissions has become more insecure, allowing for the introduction of more noise and jitter that is then presented to the DAC.\u003cbr\u003e\u003cbr\u003e\n\nHere we see the square wave generated by the SuperTubeClock™ at 42.2mHz. As you can see, the square wave still has a very discernible square shape. This means the clock is VERY fast, leaving very little time to introduce jitter and noise which can interfere with sound quality as mentioned above. Look closely at the second square wave image, each black vertical line running from left to right represents 5 nanoseconds. The time it takes the slope to go from the top bar to the bottom takes up roughly 1\/3 of that black square, which is about 1.67 nanoseconds.\u003cbr\u003e\u003cbr\u003e\n\nThink about it.. that's 1.6 BILLIONTHS of a second. Each black horizontal line in this measurement represent ~1V from top to bottom. Just as in the first wave above, the peak-to-peak travel at 42.2mHz is about 3.6 Volts, which again is excellent.\u003cbr\u003e\u003cbr\u003e\n\nThis kind of speed is crucial to ensure accuracy in detail retrieval. This in turn introduces less noise and jitter, resulting in better transients, increased clarity, improved dynamics, and a pure, musical tonality.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:- \u003cbr\u003e\u003cbr\u003e\n\n•Audio Formats - PCM: 16-32Bit, 44.1kHz-192kHz DSD: DSD62-DSD128 (DoP Mode)\u003cbr\u003e\n•USB - PCM: 16-32Bit, 44.1kHz-192kHz DSD: DSD62-DSD128 (DoP Mode) OS Drivers: Windows, Mac OS\u003cbr\u003e\n•Coaxial (RCA) - PCM: 16Bit-24Bit 44.1kHz-192kHz DSD: DSD64 DoP Mode)\u003cbr\u003e\n•Optical (TOSLINK) - PCM: 16Bit-24Bit 44.1kHz-176.4kHz DSD: DSD64 DoP Model)\u003cbr\u003e\n•AES\/EBU (XLR FEMALE) - PCM: 16Bit-24Bit 44.1kHz-176.4kHz DSD: DSD64 DoP Model)\u003cbr\u003e\n•Operation Mode - Asynchronous USB Audio 2.0 Class\u003cbr\u003e\n•Outputs - Stereo RCA Out\u003cbr\u003e\n•Freq.

That's why toroidal power transformers are used in the very best audio products. Compared to standard transformers, toroids radiate about 1\/10 the magnetic field thatpollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever. They are massive, resulting in a preamp weighing a substantial 39.6 pounds.\u003cbr\u003e\u003cbr\u003e\n\nTUBE RECTIFIED\u003cbr\u003e\n\nIn the world of preamps, experts agree that tube rectification is the gold standard. It’s quieter than solid state rectification, dropping the noise floor. And it offers the most natural, textured, and vibrant presentation because the circuit is now pure tube. But because it is expensive to implement, you’ll only find it in the top of the line models typically costing  £10,000 or more. Finding a preamp using one rectifier tube is sweet. PrimaLuna goes even further using two 5AR4 rectifier tubes in a dual-mono design to present your music with a three-dimensionality that will give you goosebumps.\u003cbr\u003e\u003cbr\u003e\n\nJAPANESE ALPS BLUE VELVET POTENTIOMETER\u003cbr\u003e\n\nThe best tube preamps use analogue volume controls. Not volume control chips. Look inside the most well-known brand of tube preamps and you will see a chip called a DS1666-10 Digital Resistor IC. At Primaluna, we understand the temptation to use this chip as they cost £4 each (half that in quantity!). The preamp will sound fine and be quiet, but true to “chips” it will add an electronic “sheen” to the sound. PrimaLuna prefers analogue. And we use the Gold Standard in motorized potentiometers:  The iconicAlps Blue Velvet. Why? Because they track perfectly, stay quiet, and don’t sound like chips!\u003cbr\u003e\u003cbr\u003e\n\nSUPERQUIET LINE INPUTS\u003cbr\u003e\n\nInput selector switches leak noise and signals from other sources, as they never turn off the other inputs completely. And, they deteriorate with age, requiring the use of cleaners. Many are mounted on the front panel requiring long runs of wires to the back panel inputs. These wires pick up stray noise from RF and EMI.\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you thebest connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.\u003cbr\u003e\u003cbr\u003e\n\nPOINT TO POINT WIRING\u003cbr\u003e\n\nYou spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.\u003cbr\u003e\u003cbr\u003e\n\nDUAL-MONO DESIGN\u003cbr\u003e\n\nExpensive and exotic preamps always use a dual-mono design to achieve a level of imaging not possible otherwise. Most manufacturers don’t employ dual-mono because of expense. It requires two power transformers, double regulation circuits, and in fact….everything is double. In effect, dual-mono means building two discrete and separate preamps into one box. It is so expensive to build, it’s a rarity even at the highest price points. All PrimaLuna preamps are dual-mono for the ultimate in stereo imaging and a sense of space that goes on forever.  \u003cbr\u003e\u003cbr\u003e\n\nSMARTGAIN DESIGN\u003cbr\u003e\n\nA preamplifier is typically not required to add any gain to your system when you are using it. It is usually lowering gain from the source you are listening to. The number one complaint from audiophiles about preamp performance is noise. So why is it that so many manufacturers design preamps with 20 to 27dB of gain? And you wonder why there is \"hiss\", and why tubes go noisy or microphonic? PrimaLuna preamps use SmartGain. With a gain specification of only 12dB, you will find your PrimaLuna preamp is as quiet as a church mouse. If tubes are less than perfect, you may never know it because they are not amplifying as \"loud\".

Having triode only is VERY limiting.\u003cbr\u003e\u003cbr\u003e\n\nThe best option is to have both triode and ultra-linear.

They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don't have the bandwidth. We use lower power to extend tube life, and bandwidth to give you slam. Transformers are the most expensive components in an amplifier, so manufacturers save money by using ‘off the shelf’ units available on the market. PrimaLuna output transformers are custom-designed, wound in-house, and massive. One reason why no other brand sounds like a PrimaLuna. \"The flat tops and bottoms of these squarewaves correlate with the amplifier's extended low-frequency response; PrimaLuna's output transformers are of excellent quality.\" -John Atkinson, Stereophile Magazine\u003cbr\u003e\u003cbr\u003e\n\nSUPERQUIET LINE INPUTS\u003cbr\u003e\n\nInput selector switches leak noise and signals from other sources, as they never turn off the other inputs completely. And, they deteriorate with age, requiring the use of cleaners. Many are mounted on the front panel requiring long runs of wires to the back panel inputs. These wires pick up stray noise from RF and EMI.\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna has a better way. Instead of a switch, input selection is done using premium quality sealed relays mounted in the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so noise and signals from other sources can’t leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.\u003cbr\u003e\u003cbr\u003e\n\nADAPTIVE AUTOBIAS\u003cbr\u003e\n\nWhat most companies call Auto Bias is actually \"Cathode Bias\"- A commonly used method that is cheap to make, and often found in guitar amps, but also £20,000 high end audio amps. It reduces the available power of the amp and runs the tubes hard, meaning shorter tube life and failures via \"shorts\".\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna's Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time. More important, it is the ONLY circuit of its kind that is truly \"adaptive\" by addressing \"tube pinch off\" at higher volumes, therefore reducing distortion by over 50% and greatly extending tube life. Adaptive AutoBias is completely passive and NOT in the signal path. The result is low to no maintenance, long tube life, and the lowest possible distortion for amazing sound.\u003cbr\u003e\u003cbr\u003e\n\nAdaptive AutoBias also provides unparalleled flexibility by allowing use of almost any tube on the market today. It even has a fine-tuning switch for EL-34 and KT88\/KT120\/KT150 tube types.\u003cbr\u003e\u003cbr\u003e\n\nPOINT TO POINT WIRING W\/ SWISS MADE WIRE\u003cbr\u003e\n\nYou spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.\u003cbr\u003e\u003cbr\u003e\n\nEVO 300 and EVO 400 models use Swiss-made, silver-plated, oxygen-free continuous crystal (OCC) copper with a Teflon dielectric in the critical signal path for superior signal speed and increased clarity.\u003cbr\u003e\u003cbr\u003e\n\nSMARTWATTS - EXTENDED TUBE LIFE\u003cbr\u003e\n\nTube life is simply a matter of how hard you run the tubes. That’s it. The only way to extend tube life is to run them as close to zero as you possible can, making sure it is not so low you go into crossover distortion. The life of a tube will depend on two things: Plate and screen voltage.\u003cbr\u003e\u003cbr\u003e\n\nIf the plate and screen voltage is high, you are more likely to get tube shorts when you turn the amp on and you get cathode stripping which greatly effects the cathodes ability to spit out electrons. Manufacturers that run the hell out of tubes to pump up their power ratings will never tell you what voltages they use. They’ll say it’s “proprietary” as if it’s some secret sauce. There is no such thing. But if they told you that they used 575, 600, or even 625 volts you probably wouldn’t buy. We proudly tell you our tubes run at just about 417 volts for the plates and screens.\u003cbr\u003e\u003cbr\u003e\n\nPrimaLuna runs their output tubes at a minimum dissipation without going into crossover distortion. When you look at our amps, they provide less power from each tube. With KT-120’s as an example, a PrimaLuna will give you only 21 watts per tube. So running a pair of them you get 42 watts. That’s a lot of power, but the demands per tube are a fraction of some manufacturers that give you 100 watts from a pair of KT-120’s. It’s a cheap way to get big power, and it’s cheap. In fact, free. To get more power the right way is expensive. It requires bigger transformers, sockets, wiring, resistors, capacitors, and the tubes to do it. Which is exactly what PrimaLuna did. But we didn’t stop there.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:- \u003cbr\u003e\n\nPower:\u003cbr\u003e\n\nUltra-linear: 42 watts x 2 (EL34)(8Ω, 1% THD)Power\u003cbr\u003e\nTriode: 24 watts x 2 (EL34) (8Ω, 1% THD)Inputs5x Stereo RCA\u003cbr\u003e\nStereo RCA HT Bypass: Outputs 4 \u0026amp; 8 Ω\u003cbr\u003e\nRCA Stereo\/Mono Subwoofer\u003cbr\u003e\nStereo RCA Tape Out: Freq.

That means all-tube and dual mono. The only thing we left out was tube rectification because it isn't appropriate for this application. It took two years of research and experimentation to perfectly pair it with the output circuit designed by Jan de Groot who has designed all of PrimaLuna’s MOSFET circuits, and was behind all the Sphinx Audio designs from 1995 to 2000.\u003cbr\u003e\u003cbr\u003e\n\nApart from combining tube magic with solid state control, the EVO 300 Hybrid focuses on lowering source impedance while also lowering noise, offering the highest possible fidelity and bandwidth.\u003cbr\u003e\u003cbr\u003e\n\n\u003ch3\u003eTube in the Front, Solid State in the Back\u003c\/h3\u003e\nThe input stages of the EVO 300 Hybrid use two 12AU7 tubes in the gain stages, and four 12AU7 driver tubes. The doubled driver tubes ensure a lower impedance on the output stages, allowing for large dynamics, a huge soundstage, and lots of beautiful harmonics and texture. \u003cbr\u003e\u003cbr\u003e\n\nThe solid-state output stages use cascading JFETs from Linear Systems and each channel boasts two complementary pairs of MOSFETs from Exicon. These MOSFETS are exotic and custom-designed and built and are not available to anyone else! The setup is calibrated to offer the lowest impedance, and the 100 W into 8 ohms (160 W into 4 ohms)  power sounds massive, allowing this amp to preserve tube glory while offering the excellent grip, low-bass power and control that MOSFETs are known for. \u003cbr\u003e\u003cbr\u003e\n\nThe most crucial capacitors, the ones in the signal path, are extremely expensive tin-foil caps that are made in Europe. Elsewhere, even the caps outside the signal path are the top-quality models that modders use to upgrade their regular amps!\u003cbr\u003e\u003cbr\u003e\n\n\u003ch3\u003eThe Power Supply is Everything\u003c\/h3\u003e\nThe power supply in the EVO 300 Hybrid is extremely complex. Increasingly, manufacturers are realizing that there’s more to power supplies than was ever thought before and that their design has a huge effect on the sound of the amp. For example, a power supply inductor can work as a second-order harmonic filter, so every part has to be carefully considered for its sonic qualities.\u003cbr\u003e\u003cbr\u003e\n\nThe amplifier uses a custom-wound set of potted toroidal transformers for true dual mono. It also has a pair of PrimaLuna’s custom-designed AC offset killers that the company is world-famous for. There is extensive shielding in various parts of the amplifier to block any noise from the main power supply getting into the delicate preamp section. \u003cbr\u003e\u003cbr\u003e\n\nLooking into the chassis of the EVO 300 Hybrid, you will see a red glow of LEDs, reminiscent of the glow of tube filaments. This isn't just a cosmetic touch. Apart from emitting light, LEDs can function as low-noise, extremely quick diodes in electronic circuits. Designers have found that red LEDs in particular offer the best performance when used this way.\u003cbr\u003e\u003cbr\u003e\n\nThe PrimaLuna Hybrid's power supply circuits use high-performance LEDs at critical points, offering various circuits in its extremely sophisticated power supply, their own supply of low-noise electrical power.\u003cbr\u003e\u003cbr\u003e\n\u003ch3\u003eTRANSFORMER-COUPLED HEADPHONE AMPLIFIER\u003c\/h3\u003e\nOne of the best headphone amps in the world. Most  integrated amps use a solid state op-amp chip for running headphones. Stand alone headphone amps will vary in quality like any other amplifier. Headphones are simply small speakers that require less power. Some amps will use smaller output tubes that groan to have enough dissipation to run power-hungry planar headphones. This is how we do it. We simply took advantage of the fact that we make the best tube integrated amplifiers. We  designed  the  same way  with the  Hybrid  Integrated Amplifier. Now you don't have to pay for a separate state of the art headphone amp. PrimaLuna integrateds are the favorite of owners who use everything from Audeze to Hifiman to Sennheiser.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\n\u003ch3\u003eFLOYD DESIGN SPECIFICALLY-MANUFACTURED MOSFET SOLID-STATE POWER AMPLIFIER\u003c\/h3\u003e\nToo often, hybrid amps turn out to be less than the sum of their parts – a mismatch, both technically and sonically. It's essential to choose solid-state components that behave similarly to a tube. PrimaLuna EVO 300 Hybrid Integrated Amplifier's MOSFETs, used in the power stages, share similar characteristics with tubes.\u003cbr\u003e\u003cbr\u003e\n\nFloyd Design's Jan de Groot has created amps with MOSFETs for 26 years. These MOSFETs are specifically designed to pair with our most successful PrimaLuna pre-stages, matched for the best sound quality possible and mounted it in one chassis;  Et voilà!\u003cbr\u003e\u003cbr\u003e\n\nThe PrimaLuna EVO 300 Hybrid Integrated Amplifier is unlike any other HYBRID Integrated Amplifier on the market. You can SEE that, and you can HEAR that. We wanted the BEST HYBRID possible, and we knew it would become a more expensive unit. After the final fine-tuning and listening tests, we can easily accept and justify that!","brand":"PrimaLuna","offers":[{"title":"PrimaLuna EVO 300 Hybrid Integrated - Black","offer_id":57415676592460,"sku":"PRIMALUNAEVO300HB","price":5415.0,"currency_code":"GBP","in_stock":true},{"title":"PrimaLuna EVO 300 Hybrid Integrated - Silver","offer_id":57423969780044,"sku":"PRIMALUNAEVO300HS","price":5415.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/primaluna-evo-300-hybrid-floyd-black.jpg?v=1777557118"},{"product_id":"primaluna-evo-100-tube-phono-preamplifier","title":"PrimaLuna EVO 100 Tube Phono Preamplifier","description":"The EVO Tube Phono Preamplifier is the newest and first member of affordable, high-quality tube phono products.
