I have the Dreamcatchers in a small office. I intially tried running them with a Cambridge 540A and it was just ok. I went ahead and slid in a 35 year old Marantz 2238 receiver and it was a completely different story. Crisp, Clear, nice kick considering the speaker size. It really opened them up. I was almost going to sell them before I did the swap I am extremely happy with this combo.
One thing this really did for me was really open my eyes with regards to some of the less expensive integrated amps on the market, this old Marantz just smokes that Cambridge as far as SQ. Hope this helps.
