I have a 568, 596, 5K's l/c/r and Difinitive technology speakers at the rear.

I started with a DSP-A1, but once I heard the Meridian processor I had to get it, I also think that Meridian processors are the most musical available. I want to buy a 861 at some point, wife permitting(-:

I am very happy with the 5K's.

Martin.
