I have been a fan of tripath for some time, ever since I had a Trends TA10.1 which I modified and which sounded bloody fantastic on the Sachiko's (FE206En) I had a the time. I now have the Sure 4 X100W tripath board as it is four channel which is what I need to run my OB's actively. I think it sounds great. I have also heard a selection fo 'chip' amps (LM1875, 3886) and these too sound brilliant.

All in a ll a cost effective way to get good sound.
