The Head 2 also working as great tube preamplifier capable to drive all power amplifier even with very low input impedance. ...[more]

Jadis consists of a small band of valve devotees who have one over-riding philosophy: love for a job well done. And there is no denying that their passion is reflected in the many amplifiers, preamplifiers, CD players and DACs that have delighted thousands of music-lovers for more than three decades.     Although their products go through various circuitry updates over the...[more]

The JA80 is a power amplifier working in pure class A. It is the first amplifier created by the JADIS in 1983; it has been upgraded several times but remains the flagship of the brand.   It works in a "push-pull" configuration with triple load and autobias. It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34.   The MkII version brings...[more]

DA 5 ' " The truthful lying" that Malraux spoke of ' J-M.P  in DIAPASON April 1996 The DA 5 belongs to the same price range as the DPL2, and is often associated with it in specialist reviews. The coherence of the whole in timber and dynamics is undeniable. It is able to drive loud-speaker systems of medium efficiency without any problem of treble distortion. ...[more]

DA 7  " The grand illusion" - Jonathan Valin l The DA 7 is a monoblock amplifier of 2 x 100 watts with an imposing presence : its transformers arrest the eye and at the same time create a visual barrier. ...[more]

Art Dudley, one of the most famous and well-respected reviewers in the industry, reviewed the DiaLogue Premium power amp as stereo amp, not even in the more powerful monoblock mode.  He was swift to say "I tried to fiind fault with the PrimaLuna DiaLogue Premium.  I failed."  He went on to say that he has had the pleasure of reviewing some remarkable amplifiers, and that the DiaL...[more]

The DiaLogue Premium Series also includes the same innovative circuits found in the ProLogue Premium series, that protect the amp and improve sound at every level: -BTI-circuit. BTI stands for "Bad Tube Indicator." On the chassis’ deck in front of each power tube, is a small LED that lights up if the tube goes bad. The circuit then puts the amp into protection mode.  With other brands,...[more]

GS150 POWER AMPLIFIER An amplifier is the workhorse of any system – it is responsible for receiving small signals from a preamplifier or source component, and developing them into larger currents to control a loudspeaker. To that end, the GS150 has been designed to seamlessly integrate into any system and steadfastly perform its task. Challenging source material and difficult sp...[more]

We call it "Hybrid Drive" because that’s how it works.  As in the REF110, a JFET input (for low noise) feeds a 6922 dual triode gain stage, which in turn feeds a 6H30 dual triode cathode follower which drives the outputs through our proprietary coupling capacitors (first used in our REF3 preamp).  This vacuum-tube input/driver arrangement sets the stage for superbly musical perform...[more]

Incorporating the best electronic elements of the original ProLogue Four and Five, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Series is an engineering marvel — a single, stereo power amplifier that sets a new benchmark in high-performance audio with the following features: *Innovative, new Adaptive AutoBias circu...[more]

The thick front panel simply has an On/Off switch and corresponding LED and does not contain the vacuum-fluorescent display found on its more powerful siblings.  The attractive internal layout is similar in appearance to the REF210 with the right and left channel boards mounted horizontally, flanking the transformers mounted on a raised central channel running front-to-back. A small LCD displ...[more]

When Introduced i, the REF110 power amplifier proved to be one of the most respected and popular stereo power amps ever produced by Audio Research. Now it is superseded by the new REF150, offering more power, more sonic finesse, quieter operation and a more contemporary appearance. Having identical outer dimensions as the REF110, the new REF150 has much more packed into its chassis. Refined fro...[more]

The REF75 is a great looking amplifier, slightly reminiscent of our older classic designs.  The front panel has two illuminated analog power/bias meters, one for each channel.  Under each meter is a knob to switch from power output to bias monitoring for each output tube.  Bias adjustment points are accessed from the front panel, too, offering real convenience.  The outer di...[more]

The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 1/2" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and g...[more]

The VS115 revisits the classic look of the VS110 with its open architecture and natural anodized top plate – now more ventilated for better heat dissipation. Drawing upon the successful REF110 input stage design, the VS115 uses a FET input with two 6H30 triodes in each channel for gain and as a cathode follower-driver for the 6550C-equipped output stage. This allows both balanced and single-ended...[more]

The VS55 makes a wonderful companion to the recently introduced SP16 preamplifier. Together, these exciting new companion products enable you to assemble a true Audio Research music system at a more reasonable cost. Like the SP16, the VS55 represents a fresh, new design direction for Audio Research. Using an open (rather than fully enclosed) chassis architecture, the VS55 features a milled, anodiz...[more]

Its rated output of 50 watts per channel does not convey the VS60's ability to drive power-hungry, low-impedance loudspeakers. Audio Research designed the VS60 with the finest full-range speakers, not compact monitors. Dynamics are lifelike with a sense of ease normally associated with larger amplifiers. Yes, its resolving power is surprising, allowing you to hear details that were previously hidd...[more]

Absolute Sounds is pleased to introduce the VT80 vacuum-tube power amplifier to its Foundation Series. From the same design and engineering team responsible for the award-winning Reference Series, the VT80 allows the Foundation Series to be shown as a complete system. Combining an enticing new aesthetic with worry-free operation and great performance, the VT80 is a vacuum-tube amplifier tha...[more]

Since the spring of 1996 the VT100 established itself as the benchmark amplifier in its price range. Accolades from the press and music lovers grew even louder with the 1998 introduction of the MKII because of its improved dynamic swing, more refined performance, and ability to drive so many "difficult" loudspeakers which normally could not be used with other vacuum-tube amplifiers. Well, the VT10...[more]

The VT200 vacuum tube stereo power amplifier is the most powerful of the three VT-series models. Rated at 200 watts per channel into a wide range of speaker loads, the VT200 encompasses a "dual mono" circuit layout reaching back to the massive single power transformer. Eight matched pair of 6650C output tubes and 674 joules of distributed energy storage give the VT200 unwavering control over the m...[more]

Based on the same circuit design as the VT100 and VT200, the VT50 features a dual-mono circuit layout reaching back to the large power transformer. Two matched pair of 6550-C tubes provide the output (one pair each channel), while four 6922 twin triodes serve as input and driver tubes (two each channel). Constant-current source technology (as used in the Reference Series) help maintain output stag...[more]
