I'm looking at the RTi28 + CSi30 as a replacement for the speakers in my Onkyo HTS760. I've got a good sub (PB2+) and I'm now thinking about improving the speakers. With the price dropping on them a CC it's got my interest going. I'm hoping to talk them down to about $500 for the 5 surrounds and the center. I've listened to them in the store, which means almost nothing, and they sound fine. They also are the right size for what I want. Any opinions?
