I recently purchased the Jeff Rowland Concentra integrated amp for my ProAc 2.5 Speakers (also use Meridian 508.20 CD Player). This combination sounds very good to my ears and you might want to consider it. My experience with Levinson is their equipment is dark and not very musical. I have also owned the Threshold Stasis 200 amp and suggest you keep looking. Plinius makes an integrated amp (around $3K) that sounds good but the Rowland is much better. Good luck.
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
