The popularity of the Masterclass series has resulted in over seventeen years of continuous production, offering an excellent price/performance ratio it is easy to hear why it remains so successful.

The SPA-4 is a stereo version of the MPA-4  mono power amplifier and uses the same class A circuit. The only differences are power output and the additional flexibility of both single ended and balanced inputs.

Not every music lover can accommodate two substantial power amplifiers in their listen space, so a single SPA-4 could be the solution. One of the noticeable abilities of the SPA-4 is how well it works with smaller loudspeaker designs as well as large ones.

Control and sound stage are two key elements of the SPA-4 making it a fine power amplifier.

Standard finish options are either black or silver – please contact us directly for Sugden’s custom colour options service!
