This is an extremely impressive amplifier designed by Nelson Pass using 32 MOSFET (HEXFET) output devices. The amp uses 3 stages of gain vs. the 5 often used by its peers. The amplifier is very smooth, producing good inner detail. It is capable of driving almost any load and delivers stunning dynamic range. I performed several blind comparison with friends owning very high end amplifiers driving B&W 803s and Martin Logan electrostatics. The Adcom performed at a peer level and produced superb results. The only downside is the heat generated as they are biased AB1 towards class A operation.
