Planet 2000 Interconnect, please help

I recently got a Rega Planet 2000. It does sound a little dark. I was using DH Labs BL-1. So, I looked for an IC that would bring out the detail and add a little sparkle. I ended up with HT Pro Silway II. I was surprised when they worsened the sound. They did add a BIT more high end, but the fullness and body of the music was gone. When I reinserted the BL-1, the sound was improved. I want to know what IC I should use that will have BOTH fullness and high detail. My budget is up to $500 retail.
(The BL-1 sounded so much better when I put it back in, I almost wondered if I should just stick with them)
Thanks much!
