I have only had this incredible integrated amp for about a month and only selling due to the fact I got an amp for more than three times the price from a local audiophile friend of mine. This unit truly embodies the best of Tubes and Solid state with a bespoke preamp built in. It  will drive virtually any real world Speaker with ease. This unit drove my 4ohm Proac D48r with ease in my medium size room. To better the sound of this unit one would have to spend multiples of my selling price. Truly a world class unit from a British company that invented the solid state class A output stage and has been around for over three decades.  Below are the specs on this incredible piece of audio kit from Sugden.

The IA-4 is our 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.
