You could also try a Krell KAV-250a. Very musical, very authoritative bass (though not quite as much as the biggest amps). But by far the best combination of positive attributes in an affordable and convenient package; AND EXTREMELY POWERFUL (500 wpc into 4 ohms). I have no problem driving 90 db sensitivity speakers to 100 dB at a TEN FOOT listening distance in a 4200 cubic foot room. See the rave review in the January/February The Perfect Vision (the home theater magazine from The Absolute Sound). THEY CAN BE HAD USED FOR AROUND $2k.
Levinson vs Threshold vs Plinius vs Bry
Replacing my beloved CJ Premier 11A to power my Proac Response 2.5s with faster, deeper, tighter bass control (ie rythmic drive)without moving too far towards a dry, analytical sound. Considering the following used amps: Levinson 27.5, Threshold Stasis 200, Plinius 100, Bryston 4BST. I would really like to hear opinions of anyone with experience with these amps and especially if familiar with the Proacs. Thanks very much. Chet McHenry
