Audio Prism Gound Control vs Walker HD links??

I have read the threads on both these products. Have any audiogon members compared these two products directly and if so , what was the outcome? Just curious as what way to go.

I am running Martin Logan Odyssey's.

I run both. The Walker HDL's work differently than the GC's do and they work on a synergistic basis. you have to really try them. both have a 30 day money back guarantee. The walkers simply improved my system to a whole new level and removed grit, grain, grunge and garbage I had no idea I still had. The noise floor has dropped into the basement and absolute blackness ensues between notes. Simply astounding and lovely.

I highly recommend Cable Company to purchase them. Contact Paul Jenkins.
