This flagship amplifier, designed to celebrate Accuphase's 50th anniversary, delivers unparalleled audio performance with its Class A monophonic design.\u003c\/p\u003e\u003ch3\u003eFully balanced signal paths realised with dual instrumentation amplifier configuration\u003c\/h3\u003e\u003cp\u003eAccuphase's monophonic high-output amplifiers have been constantly refining their technology since the company's 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.\u003c\/p\u003e\u003ch3\u003eTwo totally identical power amplifier units driven in parallel\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eContinuous Average Output Power:\u003c\/strong\u003e Normal mode - 1000 watts into 1 ohm, 500 watts into 2 ohms, 250 watts into 4 ohms, 125 watts into 8 ohms.
