Интегральные усилители — Yamaha A-S801

The A-S801 is a solid-state integrated amplifier built as a mid-range two-channel hub, with enough analogue inputs to anchor a modest multi-source system. Yamaha's A-S series spans a considerable range of integrated amplifiers, and the A-S801 sits at a capable mid-tier position within that broader lineup.

Position in line

It sits above the A-S501 and below the A-S2200 in Yamaha's integrated amplifier range, with five analogue inputs and a wide rated bandwidth typical of the series' mid tier. This positioning places the A-S801 as a sensible upgrade path for a listener who has outgrown Yamaha's more entry-level A-S models but is not yet ready to commit to the considerably pricier A-S2200 flagship.

Key specs that matter

Rated output is 100 W into 8 ohms, rising to 160 W into 4 ohms, a healthy but not exceptional doubling that indicates a solid, if not oversized, power supply. Rated bandwidth is 10 Hz to 100 kHz. Signal-to-noise is 100 dB with 0.019% distortion. Damping factor is 240, giving firm control over typical bookshelf and floorstanding loads. At 12.1 kg it is a moderate weight for the output class, suggesting a competently but not extravagantly specified power supply and transformer.

Sound and use context

Expect a controlled, even-handed presentation consistent with the damping factor and moderate distortion figures - built for accuracy across a wide input range rather than a single strong tonal signature, a sensible, versatile choice for a system with several different source types.

Pairing

Five single-ended inputs at 47 kOhm impedance accept virtually any source without gain-matching issues; the 100/160 W output suits most bookshelf and floorstanding speakers without needing high sensitivity.

Alternatives

The A-S301 is the smaller, lower-power model below this one in the range. The A-S2200 moves into a higher output and build tier for larger rooms or less sensitive speakers, worth the further investment if this model's already solid 100 W figure proves insufficient. Yamaha extensive dealer network makes arranging a direct comparison against both the A-S501 below and the A-S2200 above a practical option for most buyers, helping clarify exactly where the meaningful performance jumps occur within this broad amplifier range. The five-input connectivity here should comfortably accommodate a typical multi-source system without needing an external switcher.
