The A-S501 is an integrated amplifier with phono stage from Yamaha, built with an exceptional damping factor. The A-S501 brings Yamaha's considered engineering to an accessible integrated chassis.
Key specs that matter
Three single-ended inputs plus a dedicated phono input are provided. Output power is 85W into 8 ohms, rising to 120W into 4 ohms. Frequency response spans a wide 10Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 99dB, with total harmonic distortion plus noise at 0.019%. Damping factor exceeds an exceptional 240 - a remarkable figure for this accessible price tier, indicating strong control over loudspeaker cone motion. At 435 x 151 x 387mm and 10.3kg, the A-S501 maintains a manageable integrated amplifier chassis.
Sound and use context
Expect surprisingly tight, controlled bass reflecting the exceptional 240 damping factor, combined with the built-in phono input covering vinyl directly, consistent with Yamaha's broader accessible, well-engineered Japanese engineering philosophy.
Pairing
The built-in phono input covers a turntable directly, and the exceptional 240 damping factor suits a wide variety of loudspeaker loads with excellent bass control.
Alternatives
Yamaha's own A-S701 offers a considerably more powerful alternative within the same broader A-S catalogue.
