I am in the same predicament - looking for amplification for my new ProAc Response 2.5s. I tried compared the C-J to the Bryston and found (not surprisingly) that the Bryston had much better bass control but was too bright for my tastes. The C-J was absolutely captivating for female vocals and small scale acoustic music but lacked authority in the bass and sounded rolled off at the top. So my search continues. Going to audition a Plinius SA 100 soon. If that doesn't work out i'll probably by an Audio Research VT 100 MkII which works great with the 2.5s. It has a magical combination of good tube harmonics with surprising bass slam and authority _and_ very fine resolution of detail. But I have high hopes for the Plinius.
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
