Bewith Reference R-107S Rosso
The R-107S is a compact, high performance monaural power amplifier for systems built on “one amp per channel” and “one amp per speaker”, from simple passive 2-way to digital multi-unit. Circuits from the Bewith Air Circuit tradition give a simple, sound-quality-first design that eliminates heat fins thanks to low heat generation and low power consumption in a full-discrete, full-analog layout, with a custom power transformer of low magnetic core and high purity oxygen-free copper coils. The Rosso is a version of the Reference R-107S.
