What size is your room? Having a better 5.1 might be better than adding channels. If you are unhappy with the bass the first place I would look is the subwoofer. I had the KSW-12 and now have an SVS 20-39 PC. It was a definite improvement however I think the difference is greater with music than HT. After I did some research I found that even members at the Klipsch forum didn't speak fondly of that particular subwoofer. Do you like the mains without the sub running? If so the new sub may be the way to go.

The important thing is to have a plan. Getting just new mains will leave the center weak by comparison [assuming an upgrade], and in HT the center channel is where most of the info comes from. If your time frame allows you to upgrade the center in the not to distant future you could use a phantom center which will probably sound better than what you have, until you get a matching center to the new mains. A new receiver that does DPLII will also give you improvement in 2 to multi-channel conversion. Knowledge of your budget [now and later] will help in making recommendations. And I'll say it again, IMHO a better 5.1 will sound better than a not as good 6.1 or 7.1 system and allow you to use your resources to get better gear. Tough choices.
