The largest and most powerful integrated amplifier in the Sugden family which takes advantage of the initial Sugden class A output configuration. The Pure Class A solid state output stage equipped with greater power from a custom-built transformer and low impedance supply can project and fill an enormous holographic sound stage with ‘simply more music’.
Masterclass IA4 integrated amplifier.
An extraordinary, organic, euphonic, acoustic performance, achieved by the integration of a state of the art preamplifier and the classic Sugden Class A output stage. The integrated system of pre-amp and power amp driven by individual power supplies enables the ultimate in musical performance. Just listen – you will find it worth more than a thousand words. Despite the high power installed, Sugden have included an MM phono stage of extremely high quality.
