The story
The XA160.8 has more of everything than the XA100.8: 72 power MOSFETs per chassis, a higher-capacity power supply that draws 600 W at idle, and an 11-inch-tall heatsink array. Pass rates it at 160 W per channel in Class A into 8 Ω and says the supply allows more than 320 W of Class A peaks, with a damping factor of 200. The front end is the .8 series balanced circuit with constant-current sourcing and precise voltage references, and the inputs are XLR and RCA at 100 kΩ and 50 kΩ.
Future Audiophile's Jerry Del Colliano called the XA160.8 as good an amplifier as he had heard at any price, and set out the costs plainly: heat, electricity and weight. At 123 lb each the XA160.8s are a two-person lift and need a ventilated floor position. This is the amplifier Pass positions for large rooms and loudspeakers that want Class A current without the full scale of the XA200.8.
The XP-22 or XP-32 are the matching preamplifiers. The X600.8 uses the same chassis and device count in Class AB for 600 W per channel at the same price, and the XA200.8 is the top of the Class A line.
