Here is my combo 2-channel/home theater setup. My latest upgrade were the addition of B&W 803S and HTM4S in place of B&W DM-640's and LCR-3. I'm very pleased with the update.
Upgrades that are on my mind (in order of perceived importance):
1) upgrade the power cords from the ones that came with the equipment
2) I've got the hankering to pick up another Proceed AMP-2 and bridge them.
