MUSE M50 EX Tripath TPA3123 Class T-Amp Mini Stereo Hifi Amplifier 50Wx2 with 4A Power Supply

Amp failed in less than six months of use.

The polarity of the speaker outputs was reversed, and the channels are out of phase (if not connected backwards on one channel). Other than that it is OK. Poor quality control.

This is amp is much nicer than I anticipated. The sound quality is balanced but velvety, rich and full, with no detectable distortion or background noise at normal volumes. It was a notable improvement over the older Fisher 201 it replaced. Driving a pair of Advents, it sounds gorgeous.It has plenty of power for typical household use (the highest I ever need is around 25%). There are no Q.C. issues that I could find with my unit. On sound alone, I'd guess this was an expensive piece of equipment. Unless you stumble across a lucky find at a yard sale, I doubt you could get better sound for the price.

I have this amp running a pair of Pioneer bookshelves alongside a little 6-1/2" powered sub. It has no problem cleanly delivering all the power I need from it, and can really fill a room with sound. It also did some time powering my surround speakers in my home theater before my last amplifier upgrade, and provided clean, dynamic power in that application as well.

wow..more powerful then the SA-50 SMSL and as warm and detailed as the SA-S3, muse is under-rated, especially this one...this chip has a 92% efficacy...astounding.why is that important you ask? Heat creates distortion. Less heat less distortion.more sonic sweetness, you hear the effortless power.more to come

Throw your old component system out and try this amp. It is loud, clear, and compact. It makes my iTouch sound like live symphony, and that's saying something. I use the amp with large floor speakers and the sound is very good indeed. Worth the price and then some.
