Accuphase A-300 Mono Power Amplifier Class A 50th Anniversary model

Description: Accuphase A-300 Mono Power Amplifier Class A 50th Anniversary model Description Condition: New Accuphase's monophonic high-output amplifiers have been constantly developing their technology since the company's founding, and have always led the global high-end market, delivering numerous historic products. The A-300 is a pure Class A monophonic power amplifier, born as the fifth model in the 50th anniversary of the company's founding, and the successor to the A-250, which has been highly praised around the world. The latest technology is brought together in all circuit and mechanism aspects, and the A-class operating range is expanded by improving noise characteristics and increasing output, achieving the highest level of performance and sound quality that can reproduce the rich emotions of music. The ``Double MCS+ circuit'' drives two independent power amplifier units with completely identical circuits in parallel, significantly reducing noise components. The input section of the ``Instrumentation Amplifier'', which makes up the entire amplification section, is a double configuration of completely discrete circuits, and in combination with the exquisite gain distribution with the subsequent stage, we have succeeded in achieving an astonishingly high signal-to-noise ratio. The power amplifier stage is a 20-parallel push-pull configuration of power MOSFETs, and the powerful power supply section is made up of a newly developed high-efficiency large toroidal transformer and a large-capacity filter capacitor, achieving high output, and achieving 125W/8Ω, 250W/4Ω, 500W/2Ω, and 1,000W/1Ω class A operation and ideal constant voltage drive, exceeding the previous model. In addition, the protection circuit is equipped with a MOS FET switch and edgewise coil, which have excellent sound quality and long-term reliability, and the damping factor is greatly improved by balanced remote sensing, making it possible to maximize the expressive power of the speaker. With its imposing presence, the A-300 will make a new history as the pinnacle of power amplifiers.
