Bel Canto Ref1000 MK2 Or Ref 500m ?

Sorry, I forgot to answer to your question.
I'm using only balanced interconnect from the CD2 to LS 36.5 (double box), and from the preamp to amp.

Grazie mille Giuseppe. . . keep us posted as the BC Ref 1000M continue to break in. . . and of course everyone is very interested in your upcoming direct comparison with 500M. Saluti, Guido

The Ref1000MK2 are breaking-in VERY well, and the performance increased from good to great! Now I'm very satisfied about the sound. Great transparency with dense tone ad details. I should do the comparison with the 500M this week end.

I really like the low end of the ref1000mkii's. When I first heard them, they sounded lean in comparison to my prior MF a3cr on the OHM Walshes. Once my ears adapted I determined that the low end was actually quite clean, tight and articulate. The term I have heard used that describes it is that they seem to take a vice like grip on the big OHM Walsh drivers, which is just what the doctor ordered! I can't imagine it being better. We'll see.....

I think that much of the fit as to what amp is right comes down to the match with the other components as well as the room. In my room, I started with the Bel Canto 300IU Integrated and had some bass issues at high volumes. I believe I was asking the amp to do to much with the speakers. I then went to the Bel Canto Ref500s stereo amp which had increased headroom and the bass issues did not occur. I now have the Bel Canto Monoblocks Ref 500 and that seems to be the best match. Plenty of power and headroom and very dynamic sound. They play with ease within my system. The other change I made was going to balanced interconnects. I changed from Cardas Golden Refence unbalanced to Cardas Golden Reference Balanced and in my system, it made a dramatic change. Much more fullness and slam to the sound. In addition, more bass and more extended lower bass. I got more db's and play the music at lower volumes. Everyones equipment is different and balanced is not necessarily better for everyone. It is component dependent and that is why the amp choice is not the same for everyone. What works best in one system and room is not the solution in another room with different mating components.
