Following the runaway success of The Moonriver Model 404 (Standard) the Reference version moves further, by \u00a0improving on the already excellent design platform of the Standard 404 model. The form, controls, ergonomics and design are similar, but the major difference is found at the heart of the amplifier: the power supplies."}
