Sugden Masterclass SPA-4 Stereo Power Amplifier

The SPA-4 is a stereo version of the MPA-4 and uses the same class A circuit. SPA-4 offers additional flexibility of both single ended and balanced inputs. Not everyone has room for two substantial power amplifiers in their listen space, so a single SPA-4 could be the solution. Control and soundstage are two key focuses of the SPA-4's design; it's no exaggeration to call SPA-4 a truly fine power amplifier.
