SUGDEN IA-4 (Avialable in Graphite Only**)

A large integrated, pure Class A, solid state power amplifier which can project and fill the an enormous holographic sound stage with music.

An extraordinary, organic, euphonic, acoustic performance from an integrated source. This ambitious concept of amplification combines a wide bandwidth state of the art preamplifier with an ultimate development of the original Sugden A21 pure Class A power stages.

The IA-4 is Sugdens 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.
