For Sale Sugden Masterclass IA-4 Integrated Amplifier

Further Information

Selling my Sugden Masterclass IA-4 Pure Class A Integrated Amplifier. This is the largest and most powerful integrated pure class A amplifier in the Sugden range. This is a truly exceptional sounding amp, purchased new only a few months ago.  

The pure class A power output circuit has been upgraded from the A21 series with a larger power supply and improved soothing and output capacitors. Gold plated circuit boards, full relay switching and a precision input selector switch offer further detailing. The pre-amplifier section of the IA-4 is a bespoke design, with surprising clarity and detail.  The most noticeable feature is the ability to create a large performance with depth and height on any type of music.

I have all the original packing and wrapping materials so can ship safely. See below for some of the keys specs, with further information available on the Sugden website.
