In order to vividly portray absolutely everything in various high-resolution sources; from the nuances in the most delicate performances to the highest energy-filled dynamic musical passages, Yamaha has built into this amplifier a digital power amplifier that outputs up to 70 watts per channel and features powerful drivability. Natural PWM type digital modulation with an extremely simple circuit configuration provides both natural, uncolored sound quality with higher efficiency. The low-pass filter of the latter part of the power amp, which significantly influences the sound quality, is a large coil made of low-loss, low-distortion OFC (oxygen-free copper) wire material. This simultaneously maintains the purity of high-resolution sound sources, while enhancing the power of the bass and ensuring warmth in the mid and high-frequency sounds. This delivers the best quality sound reproduction that is rich in musicality. This amplifier also features a Pure Direct switch that bypasses the tone / balance controls and a back buffer amp to improve the purity of sound as well.
