Sugden Masterclass IA-4 Integrated Amplifier

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’.

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.
