Need upgrade, sell the B&W 602 and get a tube amp?

If you listen to music more that watch movies, sell the Denon and get a Rogue Tempest Magnum Integrated. The 602's are good speakers for a fair size room. Also, what is your source?

With 2K you could do tonnes of good things with this system. I'm not sure what your priorities are when it comes to 2 channel vs HT percentages, but I can only say that money spent on some good cables like some Virtual Dynamics Audition speaker and IC's will make a world of difference. But before before upgrading cables and revealing the nasties, please upgrade the Amp and source. Your problems will be solved with some half decent tube amps like the Rogue 88's which can be had for $800 on Audiogon sometimes. Please let us know what you do most with your system, or what kind of sound you'd like to get out of your upgrades.

Truthrider, that is a fair assessment. Be sure to audition them in your system if possible. Cables will also make a world of difference.
