I have a RH750 and i couldnt be happier, there are a massive range of sounds available and it sounds extremly meaty even at low levels, a massive upgrade over my previous SWR rig!
ive tried many micro heads now and im glad i went with the TC, to me it is the most versatile and arguably the loudest class D amp out there.
also i have directly compared this to the SVT7 pro and the ampeg just cant keep up volume wise, it sounded good but didnt have the headroom for me.
