Concert Fidelity / Silicon Arts Inc.

Minimalist Audio Design for True Purity of Sound

Designers and manufacturers of some of the finest high end audio equipment available today. We are extremely proud to be associated with Masataka Tsuda and his team, and aim to provide the UK market access to this truly wonderful high end brand.

We have been left in no doubt that the Concert Fidelity pieces have been designed simply to serve the music, to ‘honour’ the music if you like, rather than to push technology for technologies sake.

Concert Fidelity electronics are designed and built by hand in Japan with a perfectionist’s fanatical attention to detail and a purist’s pursuit of optimized simplicity as the means of achieving the most musically authentic results.
Incidentally, achieving Concert Fidelity’s level of circuit optimization and simplification requires a deeper understanding of audio circuits — what is essential versus what is best eliminated — than does implementing complex circuits which contain numerous compensatory components, but once their “surprisingly simple” designs are heard, it is difficult to go back to more complex amplifiers with their colorations and limitations. This I can attest to first hand, having already owned what is, and rightly so, considered to be one of the best amplifiers made, using the Concert Fidelity system has, in the words of Dick Olsher – Re-calibrated my sonic expectation.

As a case in point, the sound of the best tube electronics should be that of the tubes themselves, and their vacuum tube products reveal tube differences to a greater degree than we have ever heard elsewhere. This results in achieving total ‘transparency’, allowing the source material to be revealed in all its emotionally involving glory, without hi-fi enhancements, artificial warmth, muddiness, distortion, or glare.

TsudaAtDesignTestStationMasataka Tsuda:

“I believe that audio technology, even, to a greater extent, digital technology, is largely perfected; speaker and amplifier technology have been largely perfected for a long time. With each new wave of products, the already perfected technology is just recycled. The audio engineer’s job should be to serve the music, rather than to try to push our technical frontiers.”

Concert Fidelity goes to perfectionist and no-holds-bared approach in design and manufacture because they feel that discriminating customers will notice the subtle design touches and will readily hear the difference they make in expressive nuance and musical enjoyment.

Their highly optimized and simplified circuits, innovative and perfectionist layout techniques, carefully specified and matched parts, and custom transformers which may be the world’s best, allow you to hear transient speed and low-frequency extension akin to solid state along with purity, delicacy, and musicality akin to single-ended triodes. With their electronics, you will hear, superiority in the following areas, without even being analytical or conscious:

・resolution of harmonic complexity
・microdynamic expression
・transient speed for resolving rhythmic nuances
・extension and speed in low frequencies
・resolution of complex musical textures
・resolution of soundstage details, along with better presence of individual images

About the Designer

Masataka Tsuda, founder and chief designer of Concert Fidelity, has over 35 years’ experience in vacuum tube and solid state amplifier design. (He constructed his first vacuum tube amplifier using parts from radio’s and tv sets left out for re-cycling at the age of just 10!). He is now able to combine a profound understanding of audio circuits, which allows him to see where many typical design “conventions” do not make sense, with uncannily creative inspirations and a perfectionist’s drive to pursue the limits of circuit simplification and purity in sound.

Tsuda believes that true depth of musical expression can only be experienced through circuits which do not try to artificially manipulate the signal in any way. His proprietary Direct Signal Path Technology (DSPT) is inspired by his goal to minimize the amount of time music signal spends in circuit, so that it retains the energy and life inherent in the original material.

Circuits, selection of parts, and layout are optimized so that all unnecessary compensating circuitry can be eliminated and the simplest circuitry can suffice, thus causing the least signal degradation. The result of his perfectionist drive for simplification is amplifiers of extreme transparency and the musical expressiveness of the very best SET’s without their weaknesses.

Their current product portfolio consists of the following:

In addition to the existing products, there will be the introduction of a stereo power amplifier in 2017, along with the introduction of a more affordable product line.
