Sugden Masterclass SPA-4

The Sugden Audio SPA-4 stereo power amplifier has been developed to present a holographic three dimensional soundstage where the listener can almost walk in and touch the musicians. As with all Sugden Audio products, tremendous headroom is available in which to develop a wonderfully dynamic portrayal of music in all of its moods - ‘simply more music’

The Sugden Audio SPA-4  stereo power amp has facilities for asymmetric (phono/RCA) or balanced inputs, the latter utilising a virtual transformer (discreet) balanced input circuit. The power amplifiers are symmetrical, current feedback, dc-coupled, gain stages with servo controlled dc off-set and multi emitter output devices.
