For two channel, the Musical Fidelity does get great reviews! Another option is to go with the Sierra Whitney which can be configured as a stereo power amp or a differential mono amp (sounds a bit better in mono mode). You should be able to buy it new for under the $3,500 list and it is a first class amp (in stereo mode 120w into 8ohms and 240w into 4 ohms). You might be able to get it new on a trial basis. Very smooth high end and killer bass -- smooth over the whole range, actually. Start with one and add another later as the budget allows. Nothing listed on Audiogon right now, but I recall the used prices in the typical 55-65% range. You have lots of great options. Good luck.
