I've decided to start putting together a home theater system, and I began with some floorstanding mains. I managed to get a pair of Polk RTi10s locally for a pretty good deal, but when I hooked them up I was a little disappointed with the overall sound. I'm using a Yamaha Rx-v659 receiver. Buying an additional dedicated amp isn't an option at this point.
My question is, can I get better sound from a different pair of speakers with a budget of around $500 to $550. I do have some local dealers relatively nearby that carry Mirage, PSB, Definitive, B&W, DCM, and JBL (Bestbuy), and I was wondering if I could get some recommendations on specific models. I've mostly been looking at floorstanders, but if I could get some impressive all-around performance out of bookshelves I'd certainly consider them too.
Both the Polks and the Yamaha are still returnable.
Any advice is much appreciated.
