I have had Proac, Paradigm, Mirage and Magnepan
I was waiting around, years actually, for a used pair of Proac Response 3's. After reading the Triangle reviews I bought a used pair of the Celius 202's. Given I use a tube amp and I am over 40 (hearing rolling off) they sound excellent to me. (I plotted them in my room using Room EQ and a Behringer 2496 to fix low freq problems. Even though they are rated to 40hz I get 30hz flat because my room helps. On high freqs they actually roll up a bit over 10K - even with the tube amp. I think my hearing compensates for that)
Equip - AMC Int Tube amp, Systemdek IIX with Goldring 1012GX, Behringer 2486, Denon 1250 CD with Audio Alchemy D/A and jitter reducer, Dakiom stuff, AC/DC/AC converter etc. I treat all first order reflection points - including behind my head and the ceiling.
