X-LP2 phono stage

I was wondering if anybody is using a Musical Fidelity X-LP2. How much (if any) improvement is it over the X-LPS. I am looking for a quality MM phono stage on a budget(under $400-500). I'm open to any suggestions. Some of the others I was looking at were Creek, Rotel, and Clearaudio
I have an xlp2. It really doesn't compare to the xls. The competitors to the xlp2 are the Camelot, the Black Cube, the EAR.
