Ditto Onhwy61. The MA6500 would be perfect for you since it has a loudness compensation circuit. My C712 had one and I used the heck out of it. I miss it a lot now. Also, the McIntosh will be much richer sounding than the MF gear in any case.
fuller sound at lower volumes
I am looking for a fuller, richer, and deeper sound at lower volumes. My current system is a Musical Fidelity a3.2 integrated, a3.2cd player, and Paradigm Studio 40 v.3 on stands. My room is about 18x12x8. I am thinking about a McIntosh MA6500 integrated. Or would adding a good subwoofer be of benefit?
