The X250 is a single-ended "Class-A" topology with Pass's Supersymmetry™ Balanced approach to precision component matching. His Supersymmetry™ topology was granted a United States patent in 1994. Employing a balanced gain-stage, distortion and noise are made absolutely symmetrical at the two outputs. The signal is amplified, yet noise and distortion are canceled. The amplifier uses carefully matched components in a balanced "Class A" circuit. This simple circuit contains only two gain stages. A balanced single-ended voltage stage drives a bank of high power MOSFETs, which operate as followers for a minimal amount of feedback around the output stage. The massive reference level amplifier is fully DC coupled with no capacitors in the signal path. The result is a high-frequency smoothness belying its massive solid-state power.
