Revel is the higher end Infinity, same company.
And then here is a review of the JBL Studio L tower L880 that audioholics did. I should also note that you can get these towers for less than $650 online at this moment. I can't see another pair of towers beat these right now at their current price range.

And then you have Mazer which raves about the Polk LSi9 and while I may not share his opinion (I heard them in the worst possible environment so I am certain that they are lot better), he is one of the few in this forum that I trust the most when it comes to speakers.
Also if you ask around here and at avs about Infinity you will get a ton of positive replies about the Beta series which are known to offer great bang for the buck.
ID companies are not the only place where you can get good speakers and affordable prices.
