About the Sugden A21SE
The Sugden A21SE Signature Integrated Amplifier is a special edition of the classic A21, featuring a 50% larger power supply and increased power output. It operates in pure Class A single-ended mode, providing a distinctively 'Sugden' sound with enhanced dynamics. The amplifier includes a sophisticated pre-amplifier stage for greater clarity and crystal-clear highs without added brightness. It supports five line-level inputs, one preamp output, and one fixed tape out, with high-quality RCA inputs and a five-way binding post. Both channels have their own transformer windings and relay-switched source selection.
