Sugden Audio Masterclass MPA-4 Power Amplifier
Sugden Masterclass MPA-4 Class ‘A’ Symmetrical Balanced Mono Power Amplifiers – 165 watts
The Sugden Masterclass MPA-4 Class ‘A’ Symmetrical Balanced Mono Power Amplifiers have been developed to present a holographic three dimensional soundstage where the listener can almost walk in and touch the musicians.Tremendous headroom is available in which to develop a wonderfully dynamic portrayal of music in all of its moods.
The MPA-4 has facilities for asymmetric (Phono/RCA) or balanced inputs (XLR); 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.
In the balanced mono amplifiers the two power output stages of the stereo power amplifier are connected in balanced mode giving a mono amplifier.The mono power amplifiers give single channel power twice that of the stereo power amplifier.
Among some of the gains of the balanced configuration are a much lower noise floor, even greater dynamics and a rock solid musical sound stage.
