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.
