Hello again David12, I was looking over your system components again and my bet is it probably leans a little bit onto the "revealing side" of midstream? A friend of mine had a pair of Daedalus speakers and aside from their gorgeous woodwork they were very eloquent with vocals and beautifully open and expressive. The ref 75 is probably the best sounding ARC amp made (not that I've heard them all but I have heard it several times and it's superb). Which power output tubes are you running? If you haven't tried the KT150's you owe it to yourself to do so...they are wonderful in that amp. Ironically you probably don't "Need" the extra power with those speakers but I'm sure they would add to the listening experience much more than you would imagine.
As for power cords the most important thing to do of course is to try until you find a winner which is fairly easy to do with outfits like the Cable company and any cable manufacturer who offers in home trial periods.
My enthusiasm for TWL cables is quite sincere, they really do open your system's heart and soul AND Pete offers a generous home trial period. Your stock cables can always be included with whatever equipment you're selling, just so the new owner can turn it on and know it works...otherwise just put them in an obscure box in a forgotten closet and get yourself something aftermarket. In my experience I know of no other easier way to find instant obvious improvement in your system than finding a well matched power cord for your system...it's worth the time.
Good luck with your search and happy Lissn'n!
