Ron, I owned an X-LPS not too long ago. I may be wrong, but I don't think there's a "best" cartridge for it. I was using a Denon DL-160 for a while which sounded fine. When I moved to a Denon DL-103, I lost a huge portion of the low end. I don't know what the input impedance is for the MC setting (it's not adjustable), but it wasn't a good match for the 103.
A Benz Glider should work fine with this phone stage. All three of these cartridges are nice, but the weak link is the X-LPS itself. If you're just getting started with it, I don't want to rain on your enthusiasm, but I found it to be flat compared to a slightly more expensive Musical Surroundings Phonomena. When I compared it to a Wright WPP100c and a WPP200c, the X-LPS sounded painfully two dimensional and thin. Others may have had better luck with it.
