SDA-7120Powerful and Dynamic Class G amplification offers the best characteristics Class A and Class A/B designs. Conventional Class A designs do not suffer from crossover distortion and is exceptionally transparent offering a high level of realism. However, a solely Class A design is extremely inefficient as it will always be drawing full power even with no signal to amplify, for this reason Class A amplifiers usually offer lower power output. Class AB design is a much more common and far more efficient than pure Class A, but it suffers from crossover distortion at low levels which clouds spatial details and transparency. |
