Sugden Audio A21 Series 2 Stereo Amplifier

The special edition A21SE integrated amplifier builds on the strengths of the classic A21. Offering pure class A single ended operation, the sound remains distinctively ‘Sugden’. Upgraded with a fifty percent larger power supply and increased power output, dynamics are even more impressive. A sophisticated pre-amplifier stage is another improvement on the A21. This provides greater clarity without added brightness producing crystal clear highs. The larger power supply provides greater control over a wider range of loudspeakers and improved micro dynamics for low level listening.
