The McIntosh MI128 is an 8-channel amp. The 4-CHerry is a 4-channel amp, of course.

This is for a 2-channel system that requires 4 channels of amplification per channel, so one advantage of the 4-CHerry is that the speaker wires can be kept short by bringing the amps closer to the speakers.

A system upgrade was proposed by replacing their MI128 with a pair of 4-CHerry Amps, so here's a comparison, based on specifications....
