A pre amplifier or pre-amp is the very hub of a hi-fi system. All your source equipment connects to the pre amplifier. Most common is an active (powered) preamplifier design but there do exist some passive (non powered) designs. Using a separate pre and power amplifier brings about significant audio improvements over an integrated design as it minimises crosstalk and each component benefits from its own dedicated power supply.

Audio Research LS27 Line-Stage Pre Amplifier
Audio Research LS27  Line-Stage Pre Amplifier
The LS27 is our finest LS-series preamp ever, replacing the venerable LS26 after almost five years. Benefiting from the latest developments in our Reference series, the LS27 distances itself from the competition by offering a level of performance not previously obtainable in its price range.

The LS27 not only offers remarkable resolution, musicality and dynamic impact, it is our most flexible line-stage and able to adapt to most any situation. In terms of control options, the LS27 has selectable High / Medium / Low gain settings for each input, BAL / SE input selection, Left-Right Balance control, Invert (phase), and Stereo / Mono selection. Tube hours can be monitored, there is a Processor pass-through for home theater applications, and the display is dimmable with the option of being turned off. All of the inputs and outputs have balanced XLR and single-ended RCA connectors, including six pairs of discrete inputs, a processor (unity gain) input, a monitor loop, and two sets of main outputs. A new microprocessor controls all functions. The rear panel also includes a 12V trigger and a 15A IEC connector.

Audio Research LS17-SE (LS17SE) Line-Stage Pre Amplifier
Audio Research LS17-SE (LS17SE) Line-Stage Pre Amplifier
The LS17 SE preamplifier benefits from a long tradition of exceptional preamplifier technology from Audio Research and shares many common traits with its larger peers. The Reference Anniversary has been hailed by many as the greatest preamplifier yet; it also yielded technological developments to be shared across the entire Audio Research product range. The SE treatment of the Reference 5 SE preamplifier and Reference Phono 2 SE phono preamplifier have been applied to the LS17 SE to great success, providing the listener the ability to hear deeper into the performance and overall better musicality in a more affordable package.

Jadis JP200MC Pre Amplifier
Jadis JP200MC Pre Amplifier
Built with 4 line, 1 MM and 1 MC input the JP200MC will allow you to connect all the analog sources you migh want to use. The phono stage will accept any cartriges even the ones with a very low impedance. Moreover this is a 4 blocks unit, with separatedand over sized power supply and a switch that allows the user to switch the phase to his convenience. The JP200MC include all the ingredient that make great sounding preamplifier.

Jadis JP80MC Pre Amplifier
Jadis JP80MC Pre Amplifier
The Jadis JP80MC is the most well known preamplifier made by Jadis. Built with 4 line, 1 MM and 1 MC input the JP80MC will allow you to connect any analog sources you migh want to use. The phono stage will accept all type of cartriges even the ones with a very low impedance. Also, the power supply is over sized and separated in order to preserve the fragile audio signal. Enormous technical effort were made to develope this peace of equipmentand these efforts had only one purpose: the ambition of biulding the best preamplifier in the world.

Jadis JPS3 Pre Amplifier
Jadis JPS3 Pre Amplifier
Phono preamplifier with separate power supply. This Jadis includes an MM and MC phono preamplifier that uses three ECC83 for MM and 2 6DJ8 for the MC stage. As for the JPS2, its specific power supply recreates a voltage for the module with a 80 Hz frequency in order to avoid problems that can occur due to the 50 or 60 Hz frequency from the mains supply. The high voltage is regulated by two tubes: 1 x EF86 and 1 x EL84.

Jadis JPS2 Pre Amplifier
Jadis JPS2 Pre Amplifier
The Jadis JPS2 is a line preamplifier which uses 3 ECC83 for the line function plus a ECC82 tube to adapt the impedance on the CD entry. Its specific power supply recreates a voltage for the module with a 80 Hz frequency in order to avoid problems that can occur due to the 50 or 60 Hz frequency from the mains supply.

The high voltage is regulated by two tubes: 1 x EF86 and 1 x EL84.

Jadis JPL Pre Amplifier
Jadis JPL Pre Amplifier
Built in stereo preamplifier, the JPL includes 5 line imputs and one tape with monitoring.

The JPL will bring you an inherent sense of dynamic gradation, but also soundstage transparency and mastery over the elements of spatial resolution. I never felt that the Jadis was holding back or blunting the power and rise-time of orchestral peaks. I've never heard a preamp so convincingly delineate the dynamic range from soft to very loud. This is one of those rare products guaranteed to dramatically improve your system. Be prepared for a dynamic eruption that will nudge you much closer to the illusion of live music.

Jadis JP15 Pre Amplifier
Jadis JP15 Pre Amplifier
The Jadis JP-15 stereo preamplifier makes a perfect and homogenous couple with the monoblock Jadis JA-15 amplifiers. Its design is in the pure Jadis' tradition. With a simple diagram this preamplifier will really breathe life into your music.

The JP15 delivers a wonderful sound, dynamic with a deep and wide soundstage. Homogeneous on the whole music spectrum, it will deliver any parts of the harmonics with a constant fluidity with a disconcerting ease. “Elegant” is the word that fits the best this jadis.

Krell Illusion II - Pre amplifier
Krell Illusion II - Pre amplifier
The Illusion II is the perfect centerpiece for a world class digital and analog audio system. Added to the normal selection of balanced and single- ended inputs are five digital inputs. The digital module features AES/EBU, coaxial, and optical digital inputs for use with streaming devices or other digital sources.

DESCRIPTION :

Circuitry Highlights: the Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Illusion II shares the same design philosophy as its bigger brother, the flagship Illusion preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder - bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting.

Krell Illusion - Pre amplifier
Krell Illusion - Pre amplifier
Kell announces the Krell Illusion preamplifier. An Ideal companion for the new Class A series of iBias power amps , the Illusion preamplifier is a perfect centerpieces for a world class two channel audio systems.

The Krell Illusion preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. 1.5 MHz open loop bandwidth in a zero feedback, balanced, Krell Current Mode design terminating in Krell CAST. The Illusion preamplifier extends the Krell tradition of separating the power supply from the audio circuitry in our flagship preamplifiers. Sharing the new Class A iBias power amplifier aesthetic and featuring Krell CAST technology, the Illusion preamplifier is the ideal match for the new Solo 375 and Solo 575 power amplifiers.
