Overview

The Yamaha A-S301BL is an integrated amplifier weighing 19.8 lb, sold under Yamaha's own amplifier technology line. Beyond weight and brand, this listing gives no power, channel or input specifications to go on.

Buyers used to comparing amps on watts-per-channel will not find that figure in this listing, since power output, channel count and input types are not stated. The 19.8 lb weight is consistent with amplifiers built around a traditional transformer rather than a lightweight digital design, though that is an inference from build weight rather than a stated spec.
