I owned the response 2.5's for about three years and I still dream of them years later. I drove them with all Cary gear at the time as well (SLP 94, SLM100 mono's 100wch) to very good sound. I really have not had that engaging of a musical experience in my place in years. they do some huge sound staging and surprising bass, a little rolled off at the very highest extremes though. midrange is also very good and very involving. I suppose that's why they were copied so much. I would buy another set with out hesitation. They are best with tubes though and they are not that hard of a load but i'd say 40-50wch min to really get the bass out of them. I heard the newer ones and they have much of the old but better detail and high end but not by much.
ProAc Response 2.5 Vs. Spendor SP1
Well I truly love my SP1's but a pair of Proac Response 2.5 has come up for sale locally and I am going to look/listen at them tonight. Anybody want to way in..... Is it a bit of a sideways move or do the ProAc's offer a bit more ,for instance in the sound stage dept. Thanks, All :)
