Lab12 suono Mk2 Toroid Version (KT120) Class A Power Amplifier
This KT120 version of Suono delivers 20 watts per channel of single-ended Class A power, retaining the same top-accessible manual bias adjustment and Triode/Ultra Linear switching as the rest of the range.
It's built around the same low-noise toroidal power transformer and careful part selection Lab12 uses throughout the Suono line, aimed at a natural, fatigue-free listening experience rather than raw output.
