What cable to use with KRELL

I've made this comment before, so I'll make it again. It makes no sense whatsoever to ask what cord sounds right with a particular equipment. Now, if you had asked what cord works well with a preamp or pre-pro, this might make some sense. If a particular component requires this much synergy with a cord, then you should replace that component with another one that has a decent power supply. In general, a cord cord is a good cord with any brand component.

Why don't you mod your Krell equipment so it sounds good instead of bandaiding with power or speaker cables?

If it has Mosfet output devices, just sell it and get bipolars unless you are willing to immerse it in LN02...
