Best and Impressive Power Amplifiers

The SS-025 is one of Vitus latest designs. Based on the SIA-025 integrated amplifier this stereo amp does away with the linestage and puts a few more choice compnents inside instead. A natural partner for the RD-100 Dac/Pre or MP-D201 Masterpiece DAC with built in linestage.

For those who want the very best in performance the SS- 103 is our statement stereo power amplifier in the Signa- ture Series. With a completely no-compromise design, this amplifier will take on the very finest products from around the world, regardless of their cost!

The SM-100 was the very first power amplifier to come out of the Vitus Audio design studio. A true balanced amplifier that changed the marketplace and made clear what a monaural power amplifier should provide to the user. The initial design was housed in two chassis but we always intended to create a four chassis system to separate power circuitry from audio circuitry.

“One of the most superb sounding single-ended triode amplifier”.

The Ayon Crossfire Evo is the little brother of our famous “Vulcan Evo” amplifier.
The new driver stage for the Crossfire Evo amplifier has been completely new re-designed and is operating now by our own new AA20B driver tube as well to provide for the shortest signal path and the most direct signal flow. This mono power amplifier offers absolutely breathtaking realism, utmost neutrality, great dynamics, astounding resolution and truly realistic bass performance from our acclaimed single-ended triode circuit.

We are proud to introduce our new KT150 mono power amplifier, the Triton Evo. The Triton Evo mono blocks offer true balanced or single ended operation combined with the ability to deliver 120 watts per channel.

The new driver stage for the Vulcan Evo amplifier has been completely new re-designed and is operating now by our own new AA20B driver tube as well to provide for the shortest signal path and the most direct signal flow. This mono power amplifier offers terrific breathtaking realism, utmost neutrality, explosive dynamics, astounding resolution and truly realistic bass performance from our acclaimed single-ended triode circuit.

The result of a tour de force in the pursuit of sonic realism combined with our leading design expertise in single-ended triodes and advanced technological solutions has quickly earned the reputation of a milestone amongst high-end tube amplifier designs. 

The Luxman M-10X power amplifier flagship model replaces the M-900u and is the next step in the evolution of the flagship Luxman power amplifier series, representing what has gone before but with an eye to the future and Luxman’s 100th anniversary in 2025.

The P-7500 inherits technology features and concepts of the 40th anniversary commemorative model A-200 and subsequent M-6200 and takes these even further. Some of the highlights are a drastic reduction in noise and a significant further improvement of the damping factor.

The Epsilon Monoblock immediately makes clear that its wider power bandwidth delivers more speed, top-end air and detailed resolution. It gives a precise sound, combined with an impactful bass. It has also the wonderful ability to unravel complex musical threads with grain less purity along with surprising musical dynamics. This true balanced monoblock provides perhaps the finest KT150 design performance available anywhere near its price.

All the gain stages and power stage have been re-designed and optimized as well to provide for the shortest signal path and the most direct signal flow. The result is a significant advance in sonic performance, wider and deeper holographic soundstage. It also has more fine details and greatly improved powerful bass punch, dynamics and outstanding life-like performance–free of compression effects or dynamic limitations. One of the absolutely best sounding KT150 power amplifier in the world.

Mono-Power amplifier

The Conquistador is inimitable with a unique character. Developing and designing a new project you must think unlimited and scrutinize everything. This way the Conquistador was created and it is a highlight in design and engineering art.

Audio Research is pleased to announce the Reference 160S stereo power amplifier. A vacuum-tube design, it follows in the footsteps of the internationally-acclaimed 160M monaural power amplifier, introduced in 2018, which has won multiple amplifier-of the-year honors from publications such as Stereophile, Hi-Fi+, and others.

The Reference 80S stereo amplifier continues Audio Research’s latest design effort in creating a vacuum-tube amplifier that not only redefines ultimate music reproduction, but does it in an incredibly beautiful package.

We are pleased to introduce the VT80SE, the Audio Research amplifier with the widest appeal to the greatest number of music lovers worldwide. By combining world-class performance with flexibility and features like auto-bias, the VT80SE has been an amp that is easy to take home and just forget as you enjoy your music collection again for the first time.

After two years in development, the new Reference 160M (REF160M) Monoblock Power Amplifier is built like no other, looks like no other, and sounds like no other amplifier that you have ever heard, but it is unmistakably Audio Research. It features a refined audio topology with fewer and better components in the signal-path than in previous designs, switchable Ultralinear/Triode operation, proprietary auto-bias, output tube monitoring and protection, an advanced power meter, and much more.

The Reference 750 SEL monoblock amplifier continues the story begun 25 years ago with the introduction of the Reference 600; that is, to create the ultimate, vacuum-tube amplifier with enough power to drive any speaker, and to provide a musical experience unlike any before it.

The Reference 320M amplifier was originally imagined to be a larger, more powerful version of the Reference 160M amplifier, but it turned out to be a more sophisticated amalgam of designs incorporated in other Reference amplifiers. What was shown in 2022 was a concept, not a product. The 330M is a very different beast, producing 330 watts per channel.
