Bob:
Let me first say from what I have heard of the system, I'm blown away. For the $850 I ended up paying, it's the most amazing sound system I think (for the money) you can buy. I'm running it on (as I've said before) a Sony DB-940 which is in the ES line, and it's a mid range ES receiver... it's runs 110watts x 5 channels at 8 ohms (which is what I have it set to). It's a pretty nice little unit, and I was happy with it when i was running a Bose Acoustimass 10 Series II system... but there just weren't enough highs, which is why I decided to go with the Klipsch system... my best friend has Klipsch speakers from about 2 or 3 years ago (before they started using the copper-colored woofer) and I've never heard anything like them... I think they're either Legend or Reference series, which ever were about $250 a piece for the 8" woofer version. but I digress, the problems I'm having are annoying, but I'm not loosing faith in Klipsch at all... United Audio said they're going to swap me out a new center channel and sub and try to fix the old ones and sell them open box... so hopefulyl everythign will work out... I tried to get them to upgrade me to a KSW12 for free, but they weren't too hot on that one... oh well, maybe next time :-)
