A preamplifier must keep the audio signal as pure as possible, while amplifying and routing various source signals to the power amplifier. The goal of the engineer is to achieve “a straight wire with gain” design, nothing more and nothing less. Of course, the realization of this goal is much harder than it seems, but Rotel’s experience and meticulous circuit design has produced a string of exceptional stereo preamplifiers over the years, which has been taken to new heights in the RC-1580. The RC-1580 is designed for the hi-fi purist in terms of its minimalist approach and absolute musical fidelity. Component parts, such as an oversized toroidal power transformer and special BHC capacitors, along with circuit topology, have been carefully selected to obtain the best sound possible.
