The PS Audio class d amps seem to get pretty good reviews with the overall thoughts being detailed with a good soundstage but maybe a little clinical. Remember on the trade in that you pay the shipping.
Allow me to throw out an alternative from a company that has a very loyal following... all their amps are discrete component class d, not modules.... and less money. The word on their amps is the best of solid state and tubes combined.... but no trade in.
Here are some links that may help.
