Accuphase P-7100 Stereo Power Amplifier Trade-In
Impressive power amplifier capable of delivering 1000 watts×2 into 1 ohm. Amplification stages feature fully balanced signal paths as found in high quality instrumentation amplifiers. Further refined MCS+ topology and current feedback design result in even better S/N ratio, distortion, and other performance parameters. Massive, high-efficiency 1.5 kVA toroidal transformer and 11-parallel push-pull arrangement of high-power transistors deliver enormous amounts of linear power into ultra-low loads down to one ohm.
