I have had a Belles Ref. 150A for a few years now and it has been great. I am currently auditioning the Belles Ref.350A and it is even better, more musical, delicate, detailed. I really like it. I have looked at the Pass 250.5 and Sim audio but the size turns me off. I am going to try a VTL 150 this weekend. I have spoken to some people who are very familiar with Belles and the new statement SA-100 is supposed to be nicer than the Ref. 150A. Just some options. PS, my system has gone through some changes, speakers are now Verity Audio Encore, speaker wire Nordost Frey 2m and CDP is the Naim CDX2. Shopping spree.
