    Accuphase A-300

    CLASS-A MONOPHONIC POWER AMPLIFIER

    Created to mark Accuphase's 50th anniversary, the A-300 redefines the ideal for Class A power amplifiers. 20-parallel push-pull power MOS-FETs in the output stage improves performance by 25% over conventional models with outputs of 125 W into 8 ohms, 250 W into 4 ohms, 500 W into 2 ohms, and 1,000 W into 1 ohm that set the stage for enviable constant-voltage drive. The fully discrete balanced input amplifier achieves a level of quietness that will make you forget you are using audio equipment for reproduction. The A-300’s unmatched expressiveness lets you enjoy the most exquisite pieces from the world’s greatest composers.
