It delivers 160 watts per channel into 8 ohms and 320 watts into 4 ohms, maintaining Class A operation throughout the audio frequency range up to full rated output. The amplifier uses a hybrid Class A circuit combining push-pull and single-ended Class A biasing to minimize distortion, emphasizing low and musically pleasing second harmonic distortion. It features a large, quiet power supply with increased storage capacitance, fast recovery rectifiers, and improved EMI filtering. The XA160.5 has a gain of 26 dB, a damping factor of 200, and a frequency response from 1.5 Hz to 100 kHz. Its chassis measures 19 x 11.2 x 22.5 inches and weighs 131 lbs. The amplifier is highly regarded for its dynamic performance, precise bass control, and natural speaker character reproduction. It has won multiple awards including Editor's Choice and Product of the Year from The Absolute Sound and Tone Audio. The amplifier is no longer in current production but remains a benchmark in Class A solid-state amplification.
