Hi all. As a newbie, I've recently acquired Paradigm Studio 60's v.3 for the fronts, the CC-470 center and Studio 20's for my rears. I'm looking to upgrade my old HK 320. I've read interesting discussions on NAD, Rotel and Anthems but I'm not sure which direction to go. At this point my budget is about $3K. I could just go with an amp and acquire a pre-amp later. I've heard the Parasound Halo line at a local dealer but I think that's out of my budget. Suggestions??
