A friend of mine had an Audio Refinement Complete.
Last year I showed up at his place with a with one of THESE
. We compared it in his system to the Audio Refinement and you should have seen his jaw hit the floor.
He concluded that something must be seriously out of whack with his amp, so he sent it off to Plurison, the authorized Canadian distributor and service depot for YBA. They said there wasn't anything wrong with it so when the amp came back, Bill quickly put it up for sale and sold it.
The little T amp
trounced the Audio refinement in every way except for bass and power output. Not bad for $30, eh? That's cheap enough for anyone to try.
If you can make do with 10 watts and have some basic soldering skills, then I would direct you to DIY Paradise
and go for the Charlize. It's a much better amp than the Sonic Impact. However if you need more power, then I would suggest a Gainclone...
