Best pair of towers for under $500

[Footloose301]

Looking to upgrade my fronts. Seems that I'm lacking in the midrange and I'd like a bit more there. I've looked at the Klipsch VF-36's at Best Buy but they want $475 each and can't really find them online too easily. Is there anythjng else I should look at? I was checking out the definitive tech 7006's because they auditioned great and might be willing to front the extra cash for them from eBay. However, I heard them without a dedicated subwoofer and they were great and I've got the monster AV123 15" MFW. So I think spending the extra on those 7006's would be a waste. I'm trying to stay as cheap as possible here. My current Polk T90e's have 5.25" woofers. Thinking a set of towers with 8" speakers might be the way to go.

Side note: haven't decided whether it would be smarter to buy the emotiva 3 ch amp or upgrade to the Pioneer Elite SC-27 for a bit of added power.....
