Due to their voicing, SPEC’s amps are labeled by their manufacturer as ‘real-sound amplifiers’. In this context, the ‘real-sound’ phrase has to relate to the charm Yazaki-san discovered in his beloved vintage hardware decades ago. Since all his products under the SPEC banner pursue this particular direction, it makes sense. And if anyone wonders about the class D route instead of anything else, it’s quite logic. Products powerful enough to handle modern loads far less sensitive than vintage horns was the very much practical goal, and the SPEC team’s experience with switching circuits its backbone. Put shortly, all the know-how necessary to implement this topology in the musical fashion was already on the table.

This product’s visually fabulous solid spruce base not only has everything else on top of it, but itself sits on three slightly rounded short legs made of two different types of wood. Each footer incorporates maple surround with one hickory puck embedded inside, assembled in such a way that only the latter element is in contact with ground. Subjectively speaking, aesthetics of this solution are brilliant, but influence on sonics is its primary task. At first glance I’d thought of this wooden contraption as a decoupling scheme, however its natural resonance the team SPEC exploits as a sound tuning measure. No vents anywhere in sight on the RSA-M99’s bottom also indicate its heat-free attitude and rightfully so. Regardless of how hard was this deck pushed at my place, not even once it went beyond the barely warm state at most.

SPEC RSA-M99 from afar might look like yet another minimalist if not rather regular audio box, but up close it’s anything but. Exemplary build quality, attention to details, tasteful wooden twist underneath and predictable always pleasantly cool behavior, all result in the impression of a well-engineered luxurious looker. It’s deliberately dressed to be modest and inconspicuous, yet all in all brilliantly executed if someone asks me. In today’s I didn’t even miss remote volume control knowing why was it ditched in the first place, but you might. If so, the manufacturer has you covered and that’s good.

SPEC RSA-M99’s visuals and functionality aside, its sonic profile is where things gain momentum to truly go way beyond the usual. Machines voiced this elegantly, fetchingly, palpably and insightfully at the same time, are very rare. But today’s very much class A alike attitude and beefy power output label it as a standalone case in my privy book, not quite comparable to anything else I’m familiar with, size and price wise not even close. How much any other similarly powerful class A product would set you back? How much space would it need? How hot would it be? And how heavy? If you’re not after answers to all these questions yet list class A charm and stout watts as your primary criteria, do yourself a favor and at least audition this report’s SPEC. 

 

An amplifier is a musical instrument

At the core of our concepts is the idea that the amplifier is a musical instrument. By supporting the chassis with a combination of woods, RSA-M99 reproduces a beautiful sound like a genuine musical instrument.

A wide, solid spruce board is closely attached to the entire bottom surface of the chassis. Spruce is the same type of wood used to build violins.

Wooden feet of maple with hickory embedded in the center. These foot pieces are designed in such a way that only the hickory located in the center is grounded.

Wooden soundboard with wooden feet vibrate with the audio signal playing a natural sound.

Blending various capacitors.

By blending various capacitors, a sophisticated and expressive sound is reproduced.

“HIBIKI-ICHI” was developed with the goal of rapid response and natural tone in collaboration with world renowned capacitor manufacturer “NICHICON”. The “HIBIKI-ICHI” brings out even more texture for a more musical sound.
JAPANESE KANJI are written on the surface of the capacitor. This KANJI is pronounced as “HIBIKI-ICHI”, and ‘’HIBIKI” means vibrancy.

SPEC sticks to the R-core transformer.

The R-core transformer brings out a dynamic and powerful sound.
This same transformer is being used in the top of the range model.

Shield structure and EMC coating

The R-core transformer and other components are separated by a shielding structure. In addition, EMC coating is applied to the inner surface of the chassis, reducing internal electromagnetic noise.

High driving ability is the foundation of SPEC REAL SOUND.

High driving ability is an essential part of SPEC REAL SOUND.
In order to reproduce the sound with such musicality, the speaker drive ability is incredibly important. This is because it is necessary to drive and stop the speaker instantaneously.
” Class D ” is excellent in the speaker drive ability and can reproduce the musicality of live performance sufficiently. On the other hand, the PWM system is adopted at the front of the “CLASS D” block. Since the PWM system is composed of analog circuits, it can amplify a small signal without losses. For a beautiful sound, it is important to faithfully reproduce many small signals.

Beautiful soothing rings of warm yellow lighting

The yellow rings of light emitting from the volume control knob and input selector will contribute to a relaxing ambiance in any setting.
