I love the ProAcs. I'm not sure why everyone always forgets about Ayre. I have an Ayre V3 and I believe this amp is better sounding than all of the above and is about as close as a solid state amp can get to being a tube amp. (also with power and detail in the low frequences) They can be had on the used market for 2K and under just make sure that you at least get one with the first upgrade. Mating these with a good tube preamp is a match made in audio heaven. I use an Audible Illusions Modulus 3A. This is a very musical combo and will beat hands down all of the amps mention in this post. Do yourself a favor and go out and hear one, you won't regret it. Best of luck in your quest!
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
