Many are based on a push-pull output stage and the claim \"class A\" is therefore strictly untrue.

It fully complies with world-wide energy and environmental legislation.\u003cbr\u003e\u003cbr\u003eEverything about this headphone amplifier is incredible but true! The Graham Slee Entheos (enthusiast's) Series Novo stereo headphone amplifier is a discrete solid state transistor configuration, using an IC voltage regulator. There are six transistors per channel. The \"fast\" voltage amplifier stage uses a current feedback input and a current source to drive a small signal transistor class AB push-pull output stage. The output is capacitively and resistively coupled to prevent headphone damage\/short circuit damage and an output impedance reduction network minimises any signal distortion these components could add. The Novo uses multi-path negative feedback to reduce distortion without degrading the musicality of the signal.\u003cbr\u003e\u003cbr\u003eThe Novo is supplied with an Energy Efficient plug style AC\/DC mains adapter power supply for universal mains use: 90-250V ac; supplied with a selection of plug heads to suit the customer's mains outlet. The power supply is of the switched mode type and sensitive users may detect a slight tingling sensation from the Novo case: this is normal and within world safety standards, but can be eliminated completely by connecting a wire to the Novo \"aux ground\" post; the other end to earth (either mains earth or an earth spike - seek qualified assistance if unsure). When connected to an earthed source this wire will not normally be required. The switched mode power supply emits an ultra-sonic whistle which cannot normally be heard, but in the presence of other persistent noise (such as air-con, refrigerators etc) a beat frequency (chirping) may be heard. Careful positioning will minimise this effect.\u003cbr\u003e\u003cbr\u003eA Chained set of phono\/RCA jacks enables the stereo input to be routed to other equipment such as a power amplifier. The input impedance is greater than 39 kilo Ohms so as to be virtually transparent to the source.\u003cbr\u003e\u003cbr\u003eThe output jack is designed for standard 1\/4 inch\/6.35mm headphone plugs (B-gauge) and can also be used with tapered A-gauge plugs. Headphones of impedance 8 - 2,000 Ohms may be used but best results will be obtained with impedances of 16 - 600 Ohms. An impedance reduction network reduces the driving impedance \"seen\" by the headphones and compensates for the headphone's cable capacitance, leading to a more focused musical image than purely resistive or power-amp configuration headphone amplifier outputs. It also reduces the apparent differences between dissimilar headphones.\u003cbr\u003e\u003cbr\u003eThe volume control can be set at any position to give comfortable listening. Unlike Hi-Fi amplifier volume controls, it can be set at any position and still give excellent performance.

These are not \"boutique\" or \"designer\" components but components selected on real technical merit, and the difference they make, on listening, is obvious.\u003cbr\u003e\u003cbr\u003e\n\nIt differs from the Jazz Club phono stage in its internal grounding method as well as its equalisation network impedances. The grounding method has been optimized further to extract even more of the subtle detail, which takes the listening experience another step closer to reality, whatever the music's genre. The EQ network impedances have been lifted to further exploit the ultra-high slew rate of its amplifier stage. These improvements make the Revelation phono stage and the Reflex on which it's based the ultimate in live sounding phono stages, as attested by Michael Fremer comparing live and reproduced music performances.\u003cbr\u003e\u003cbr\u003e\nLike all our wideband designs, best performance is obtained by the unit being powered continuously, and a period of \"burn-in\" (approximately 3 weeks) should be observed for its components to fully form and stabilize. To ensure proper continuous correct operation, the Revelation phono stage is supplied with our IEC approved PSU1 in-line power supply unit. Voltages and cord-sets are country specific and are included with the PSU1\u003cbr\u003e\u003cbr\u003e\nThe cartridge sensitivity and gain is fixed for Moving Magnet or High Output Moving Coil pick-up cartridges and the input impedance is 47k Ohms.

A driver is not needed, and you can simply cancel the search.\u003cbr\u003e\u003cbr\u003e\n\nTo prove it's there play some music: the easiest way to get playing is to use your file explorer program (such as Windows Explorer) and locate your music folder, select the tracks you want and right click \"add to media player playlist\" - simple! This will open up your default music player and play the selected music.\u003cbr\u003e\u003cbr\u003e\n\nYou might want to be more adventurous and install a dedicated player such as Foobar (for Windows). You will have to select 'USB Audio CODEC' in your playback preferences output configuration for it to play to the Bitzie.\u003cbr\u003e\u003cbr\u003e\n\n\nHook Up Your Bitzie USB DAC To Your Phone:\u003cbr\u003e\n\nWith an \"On The Go\" adapter in conjunction with a USB cable, the Bitzie can take digital audio from almost any up to date Android phone or tablet - making it a great hi-fi USB headphone amplifier. It has been tested with Samsung S3, S4, S5, S6 and Huawei Ascend\/EE Kestrel phones.\u003cbr\u003e\n\nIf you use an iPhone (including iPhone 6) or iPad you'll need the \"lightning adapter\" in conjunction with a USB cable (most models are compatible).\u003cbr\u003e\n\nIt's a hi-fi USB to S\/PDIF converter!\u003cbr\u003e\n\nEven whilst playing to headphones or outputting analogue to another item, the Bitzie is always ready to convert USB to S\/PDIF.\u003cbr\u003e\n\nWhen powered up (connected to bus power or other 5VDC source) take a look round the back and you'll see a red glow around the optical connector shutter.\u003cbr\u003e\n\nSimply plug in an optical cable and connect it to a S\/PDIF \"toslink\" input and you're playing.\u003cbr\u003e\n\nHook the Bitzie up by coax cable and it's just the same - and because it's transformer isolated you won't get any noise loop issues.\u003cbr\u003e\n\nThe Bitzie makes a great interface when you want to send digital audio to a DAC in another room. Using optical you can output USB to the Bitzie on a short USB cable, and then run as long an optical cable as you want and not suffer data loss.\u003cbr\u003e\n\nAnd in tests the Bitzie has driven 6 metres of coax without a hicup.\u003cbr\u003e\n\nGet The Power Wire Bitzie Bundle\u003cbr\u003e\n\nMade long enough but not too long (0.8m per leg), the power wire is three-ended.\u003cbr\u003e\n\nBoth parts are attached to the device A-plug where data is connected but power isn't.\u003cbr\u003e\n\nPower loops back out to a second USB A-plug - connect this to your 5VDC source.\u003cbr\u003e\n\nConnect the remaining USB B plug to your Bitzie, and you've now got a DAC with \"its own\" power supply.\u003cbr\u003e\n\nGet it the wrong way round and it doesn't cause any damage - it will just wait in silence for you to swap over connections.\n\n\n","brand":"Graham Slee","offers":[{"title":"(bus powered-no power supply)","offer_id":57413237277004,"sku":"GSBITZIEUSBDAC(BP-NPS)","price":291.67,"currency_code":"GBP","in_stock":true},{"title":"(with Lautus USB Cable)","offer_id":57422928838988,"sku":"GSBITZIE-WLUSBC","price":332.5,"currency_code":"GBP","in_stock":true},{"title":"(with Lautus USB Power Wire)","offer_id":57422928871756,"sku":"GSBITZIE-WLUSBPW","price":337.5,"currency_code":"GBP","in_stock":true},{"title":"(with Lautus USB Cable \u0026 Power Wire)","offer_id":57422928904524,"sku":"GSBITZIE-WLUSBC\u0026PW","price":375.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Graham-Slee-Bitzie-USB-DAC.jpg?v=1777540509"},{"product_id":"graham-slee-majestic-multi-input-dac-digital-preamp","title":"Graham Slee Majestic Multi Input DAC Digital Preamp","description":"The Majestic makes music sound natural - not digital.\u003cbr\u003e\n\nDigitally reproduced music from your stereo streamer or CD player shouldn't sound any different to that of natural sounding analogue, but so often it does.\u003cbr\u003e\n\nThe Majestic overcomes the \"digital sound\" so all you'll hear is the music.\u003cbr\u003e\n\nThe Majestic is more than a DAC - it's a preamp too.\u003cbr\u003e\u003cbr\u003e\n\nAccepting inputs from hi-fi stereo streamers, CD players and computer hi-fi on its 3 x optical; 3 x coax; and USB input, the Majestic hi-fi pre DAC also has an analogue input. This hi-fi DAC with preamp works just like any preamp, so you don't need another.\u003cbr\u003ev\n\nDriven by a true stereo balanced DAC chipset, it has both fixed-level and variable level outputs: single-ended on fixed; and balanced (which can be used single-ended) on variable.\u003cbr\u003e\u003cbr\u003e\n\nThe fixed output will feed a headphone amplifier or you can record from it, and the variable output will drive a power amplifier - or even active monitors direct.\u003cbr\u003e\u003cbr\u003e\n\nPartner it with a pair of Proprius monoblocks and you have a complete amplifier system.\u003cbr\u003e\u003cbr\u003e\n\nWhat really sets the Majestic apart from similar pre-DACs is the lack of harshness in its sound.\u003cbr\u003ev\n\nIt's what makes it sound so naturally musical: Its digital chipset is run 2dB below full-scale to prevent the harsh sound of \"clipping\"; and its analogue filters work differently to other DACs.\u003cbr\u003e\u003cbr\u003e\n\nIts analogue filters sound more natural in five ways:\u003cbr\u003e\n\n1. their inherently fast slew-rate captures every part of the musical waveform\u003cbr\u003e\n 2. their inverting* topology does away with common-mode distortion\u003cbr\u003e\n 3. the filters operate balanced to complement the DAC chip balanced output, cancelling noise\u003cbr\u003e\n 4. they use our ultra-linear technique which gives true 180 degree local negative feedback at the most sensitive hearing frequencies\u003cbr\u003e\n 5. the filters won't \"saturate\" and distort on the loudest passages\u003cbr\u003e\u003cbr\u003e\n\nThis means you don't get harmonic artefacts - alien noises - embedded in your music.\u003cbr\u003e\n\nThose noises are the very thing that makes digital music sound so-digital and unatural.

Basic understanding sees that It leaves by one terminal and returns to another.\u003cbr\u003e\u003cbr\u003e\n\nActually, it leaves from its origin somewhere in the power supply and has to get back there. Signal current, no matter how well it is treated by the phono stage, must negotiate the inner workings of the power supply and return to its origin. Knowing that origin and how it gets back to it is crucial in understanding how best the micro-signal current involved with moving coil, returns to its origin with the least possible disturbance.\u003cbr\u003e\u003cbr\u003e\n\nThe Enigma solution was to lower the dissipation factor, improving dielectric absorption (similar to PTFE and polypropylene) for greater frequency stability such that all frequencies of signal current are treated more equally. And additionally: fine tuning its Kelvin paths and giving it a new DC cord and lockable outlet.\u003cbr\u003e\u003cbr\u003e\n\nThe result is greater clarity when using the Accession MC phono stage, in fact it's like getting the improvement the standard issue Accession MC provides, all over again. \u003cbr\u003e\u003cbr\u003e\n\nDropping dissipation factor also increased ripple current handling by 35%, and when tried with the more current hungry Majestic Pre\/DAC, a significant improvement to the solidity of the sound was evident.
