IA-4
Sugden Audio ... Rescuing Music from Technology.
The IA-4 is our flagship and most popular integrated amplifier.
Weighing in at a substantial 20 kilos the IA-4 has a purposeful look and beautiful 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.
It features an absolutely feather-like delicacy in the Treble and wonderfully smooth clarity in the Mid-range allied to a mighty punch and weight in the Bass that has to be heard to be believed!
Beautifully “musical” with your music sounding so “right” in a way you have never heard it sound before.
The largest and most powerful integrated amplifier in the Sugden family which takes advantage of the now famous Sugden Class "A" output configuration.
The Pure Class "A" solid state output stage equipped with greater power from a custom-built transformer and low impedance supply can project and fill an enormous holographic sound stage with ‘simply more music’.
An extraordinary, organic, euphonic, acoustic performance, achieved by the integration of a state of the art
Pre-amplifier and the classic Sugden Class "A" output stage.
The integrated system of pre-amp and power amp driven by individual power supplies enables the ultimate in musical performance.
