Pick up some of the Andrew Jones Pioneer speakers, or ELAC's. You can get them for a couple hundred bucks a pair (I paid $100 new for a pair of Pioneer's). They are amazing for the money. Are they perfect? No. However, to most non-audiophile folks they sound amazing. The first day I had mine someone came into my house and immediately commented on how much better they sounded than his higher-dollar speakers. He even pointed at the Pioneer logo on the speakers and made a, "WTF" face. I had $100 Pioneers and a (new $3,500) NAD Integrated I purchased here for $200 and it blew people away how good it sounded.
I'm unfamiliar with your amp, so I can't comment on that. I will say you can pick up a very decent used amp here for less than $500 that will be fine for your system. Pair with a Blue Sound and call it a day.
I've also owned the LS50's, and as great as they are that would take your entire budget. It would also continue your journey of searching for cables, better amps, etc.
I'm 95% certain you'd be more than happy with the Pioneers and a decent used amp. You'd probably in be in <$700 plus the Blue Sound.
