Also, the RTi 10's have 7" woofers.
You could just unhook your rears and go 5.1 and see if that improves anything. Otherwise the UMC-1 and amp are the best suggestion of the three you mentioned. Good luck!

+1 on this suggestion.....also, the 606 is not powering the speakers with 90 watts each when using all 5 or 7, that I can assure you. Onkyo usually states their specs for 2 channels. With 5 channels, I bet it is probably around 50 watts and even less with all 7 driven. With the RTi's and the CSi center, they'll need much more power to really open up and sing!
