Best power cord for McCormack DNA-2

I've used the Audioquest AC-12 with good results & I just purchased a Synergistic Research Master Reference Coupler for my McCormack DNA-2 standard model which is being updated to Deluxe at McCormack right now. I will let you know how S.R. cord performs when I receive my amp. Happy New Year.

I received my amp back from McCormack (excellent repair service) & hooked up the Synergistic Research Master Reference Coupler & it's excellent compared to Audioquest which still worked well but the much more costly Synergistic cable is well worth the money. Good Luck & Happy Listening, Don
