Sugden Audio Masterclass IA-4 Pure Class ‘A’ Integrated Amplifier

SUGDEN MASTERCLASS IA-4 INT AMP WS

Sugden Masterclass IA-4 Remote Volume Pure Class ‘A’ Integrated Stereo Amplifier – 33 watts

The Sugden Masterclass IA-4 Pure Class ‘A’ Integrated Amplifier is 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.

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-amplifier and power amplifier 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 a Moving magnet phono stage of extremely high quality.

Note the massive heatsinks for each channel, which are also made by Sugden.  The IA-4 is dual mono configuration for power output stages and separate pre-amplifier board. Robust toroidal power transformer with separate windings for each power amplifier and pre-amplifier. Provision of Moving Magnet phono stage for a turntable is standard. This amplifier is very like a separate pre-amplifier and power amplifier because of its configuration.
