Sugden Masterclass IA-4 Integrated Amplifier
The Sugden Masterclass IA-4 is Sugden's flagship and most popular integrated amplifier. Weighing a substantial 20 kilos the IA-4 has a purposeful look and impressive build quality. Plenty of input and output facilities are on offer including a high quality phono stage. The 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.
