I've never been overly impressed with Revel, they're nice, but in that price range there are so many better speakers - with much better resell fyi.. Look at products by KEF, used Thiel, etc. Best used deal I ever got (besides my Khorns) were the Thiel CS 2.3. I think the Thiel would slaughter the Revel. That was a properly engineered speaker, not a mass produced Harmon product.
Also, if you want great engineering look at the KEF Reference line used. I almost traded my KEF Reference for B&W 802 d2 and boy am I glad I didn't. The KEF is in a different league while the B&W is very nice, but eh whatever.
