You indicate that you're trying to drive a ML Clarity with a 25 watt per channel amp. Say it ain't so.
I've got a pair of Claritys that I'm driving with NAD M15/M25 separates. They pump out 160 watts X 7 and it takes every bit of it to makes these babies sound right.
Lots O luck
PS Most low watt amps won't handle 4 ohm loads. If that's the case with yours, I'm surprised you haven't fried your power supply.
