The Yamaha A-S801 is a transistor stereo integrated amplifier designed as the hub of a mid-range two-channel system, with enough analogue inputs for a modest multi-source setup. It sits above the A-S501 in Yamaha's integrated amplifier range, in the middle tier of the series.
Key specs that matter
Rated output is 100 W per channel into 8 ohms and 160 W into 4 ohms. The frequency response extends from 10 Hz to 100 kHz. Yamaha specifies 100 dB signal-to-noise, total harmonic distortion of 0.019% and a damping factor of 240.
Engineering and use context
The A-S801 is a conventional two-channel design with five single-ended analogue inputs, each with an input impedance of 47 kOhm. The chassis measures 435 x 152 x 387 mm, and the amplifier weighs 12.1 kg.
Pairing
The high input impedance means practically any line-level source can be connected without gain-matching problems. The power reserve suits most bookshelf and floorstanding speakers, without any need to look for especially sensitive models.
Alternatives
The Yamaha A-S2200 moves up to a higher output and build tier for larger rooms or less sensitive speakers.
