Nice system! I bet it does sound very nice. What happened to your older all Krell system? Still have it or what? I still have your old MDA-300's and KRC pre. Still loving it as much as the day I bought it. What music do you like the Regents for? I had a chance to listen to them at my local Salon a few years back. WOW, lots of speaker for the money!
ps: you would love a VK-5i in your system. My son has it and the VK-200 driving the same speakers(CS3.6) and it sounds pretty amazing in his room.
