I think you might be well served by a Crown XLI800. For some reason there is real animosity towards commercial amps but this one is dead quiet, 200WPC and they are all I use for true hi fidelity speakers. You can't touch this quality for anywhere near the price with all this home owner gear.
Try one and if you don't like it they only run just under $300 now and you can sell them for most of that used if you don't like them. Do a search for these and see what owners have to say.
