Sugden MASTERCLASS IA-4

Masterclass IA-4 integrated amplifier
The AI-4 is the built-in peak amplifier and the most popular of Sugden. With a weight of 20 kilos, the IA-4 has a strong look and impressive construction quality. The offer is very wide and includes a high quality sound stage. The Class A output circuit has been upgraded compared to the A21 series with a larger power supply and improved output capacitors. Gold plated circuits, relay switching and a precision input selector offer more details. The preamping section of the AI-4 is a tailor-made project, with surprising clarity and detail. The most obvious feature is the ability to create a great performance with depth and height on any type of music.
