Fully balanced signal paths realised with dual instrumentation amplifier configuration

Accuphase's monophonic high-output amplifiers have been constantly refining their technology since the companies founding, and have always led the world's high-end market, delivering a number of historic products. The A-300 is a pure Class A monophonic power amplifier that was born as the successor to the world-famous A-250, the fifth model in their 50th anniversary range. By bringing together the latest technology in all aspects of circuitry and mechanisms, improving noise characteristics and expanding the Class A operating range through higher output, they have achieved the highest level of performance and sound quality that can reproduce the rich emotions of music.

Two totally identical power amplifier units driven in parallel

The power amplification stage makes use of two completely identical power units, each with 10 N-channel and 10 P-channel power MOS-FETs connected in parallel. These units are arranged on the left and right side of the chassis and driven in parallel, resulting in a 20-parallel configuration. This ensures a stable balance in terms of electrical operation, weight distribution, thermal dissipation and other aspects. The parallel drive approach achieves a total allowable power dissipation value of 5.2 kW, which in turn reduces the power load on each MOS-FET, allowing each device to operate effectively in its range of optimum linearity.

Every person I invited over for a listen to the Accuphase A-300 monoblocks shared my desire to listen more and more. Their sound is that beautiful and seductive. Some amplifiers may sound more neutral. Some will undoubtedly give you more of this or more of that. But few will leave you yearning to play every piece of music you can think of as you relish how beautiful and satisfying it sounds.
