Krell HTS 'designed' for balanced cables

I read on a different forum that the Krell HTS was designed to work best with balanced cables. I have just got my unit, and was wondering whether any of the people here who own the HTS have tried both types, and whether the balanced cables did come out on top? I have decent interconnect cabling now, and was wondering whether to spend any time evaluating balanced cables.

Thanks for any feedback, Vivek
