The A21SE is a further expansion of the musical performance available from the Sugden single ended Class A output circuitry. Designed to provide more power output, greater speaker compatibility and a larger sound stage, it is not an uprated A21 Series 2 but a definitive amplifier in its own right.
The SE contains a pre-amp stage with high input impedance, high voltage gain, low noise, wide bandwidth, low distortion and low impedance to drive the Class A power stages. This pre-amp stage coupled to a fifty percent increase in the low impedance power supply enables a very dynamic sound stage to be developed with pin point imaging and fine tonal balance. An amplifier of unforced spontaneity which will satisfy the most discerning enthusiast with ‘simply more music’.
