I think your best bang-for-the-buck in that price range would be an Audience Adept Response Ar1, used for about $300. I use it in my BR system and it made a noticeable improvement in clarity, speed and transparency. I also use the AR6 in my main system and it is a near-transformative product.
I have used the PS Audio UPC and it is gopod, but will not make near the difference the AR1 will, IMHO.
