i have had experience with pro ac driven by rotel to lynnpre and power amp (klout) This sounds very good. i also drove the pro ac with classe cdp1,ocm pre and ocm500 monoblocks (800 watts) compared to my B&W 801 the pro ac is smoother speaker with great imaging. the pro ac works well with solid states amps. i heard the pro ac 2.5 driven by all copeland tubes and did not like it nor did my friends. i have driven the pro ac with levinson 332 and was excellent. The classe will work good with the pro ac in my opinion but everyone has different tastes so............
