Probably a great value for that little money but the TPA3123 chip is rated 2*25w at 4 ohm max 20w at 10% thd . 16w at 1% thd 4 ohm and 8 w at 1% thd 8ohm measured in the proper operating range at thd+N 0,08% it gives 5w at 8 ohm or 10w if you use one chip per ch and bridge them ( if the chip allows that ). If you read further at the amazon spec page muse spec it as high performance guarantee 5W RMS 8 ohm so for OP perspective he should consider it a 5w power amp . These class T and D amps suffer from a bit of creative specs so dividing the sales blurb power by a factor 4 - 10 is more like it . another hint can be the rating of the power supply ,some of the cheaper amps does not utilise these chips fully due to under dimensioned wall wart . To get the higher powers it should be feed >24 volts but muse includes a 14V 4Apower supply ? But for the price you can't beat these things :) and a boxfull of them is probably a good option in large house in need of more zones ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=98115
