This has been the perfect amp for a 5 channel system with towers that each have 2 dedicated subwoofers for a total of 4 subs in the L / R fronts. The subs are 5x7 ovals low-passed at 100hz in LSiM 705 towers playing full range.

The MM7055 is a pretty stout amplifier for the price. No complaints

Sound quality Ease of setup and use

Solid performing amplifier. I wasn't blown away with it's output, but it ably handled all types of recording quality. It took poorly recorded music and made it sound acceptable. It didn't diminish high-quality recorded music. However, it didn't enrich it either.
