Thanks guys. @ozzy, are you suggesting that the lack of openness and dynamics of the Shunyata Sigma V2 NR power cord was due to your interconnect, and not the power cord itself? And, I assume the power cord was properly broken in?
From what I gather, Shunyata is best known for their power products, and not so much for their other cables. I know many talk of “synergy” of going all in with one cable vendor, but I can’t seem to find a single vendor that doesn’t do all areas of their cables as well as their best area. For example I fell in love with Nordost Valhalla 2 speaker cables, and what they bring to the table regardless of what other cabling is mixed with them, and I have a pair on order. But, the Valhalla 2 power cord is utterly deficient in bass and presence when compared with others. One of my dealers suspects it may be incompatible with my Gryphon amplifier, as he has another customer with a Gryphon had precisely the same experience with the Valhalla 2 power cord!
As such my plan is to go all-in with either Shunyata or Transparent power cables and USB cables, with the Valhalla 2 speaker cables.
