I'm new to the screen, but have been reading some of the comments on different subjects. I was thinking of buying a Sony STR-DA4ES receiver (because of a big discount from points on my Sony card) and the Klipsch speakers. 2- RF-3, 1- RC-3, 1- KSW-15 and 2- RS-3. Are these good quality speakers for hometheater and music listening? I've read some complaints about quality, Also is it a bad idear to buy online?(acousticsounddesign.com) They have a great price and claim the speakers are new in an umopened box.. Any help would be appreciated....
