This is my very modest HT system. I get upgrade-itis about every five years or so. I've completely changed my system from interconnects to speakers to electronics in 2004. I never have a lot of money for my theatre, so most pieces are used and hopefully a good bang for the buck purchase.
As always, I'm open to thoughts, suggestions, and comments.
I've never liked your sub. It doesn't integrate well, and it sounds flabby. I think you should bite the bullet and buy some main speakers that have enough bass in and of themselves. Something like the PSB Stratus Silver. Upscale Audio sells em in piano black for 1400. I've heard these speakers and they're very, very nice. I don't think you'd be happy for very long w/ the super zeros as your mains. Sure they image like crazy, but that's about it. I know you, you're an unreformed headbanger (despite all those Diana Krall cds you own). You need slam, dammit. Buy the PSBs, move the super twos and the sub into the "pool room," and be done with speaker upgrades for a long, long time (well, maybe a new center channel at some point).
