I've had every generation of Shunyata power cords ever made, and most of the models, including the Sigma Analogue, Sigma NR, The Alpha HC, The Alpha NR (the last three current), the initial ZiTrons (Cobra and Python), the CX Python and so on.
And simultaneously I had Nordost Valhalla, Tyr (1 and 2), Frey (1 and 2) and Heimdall (1 and 2) power cords. As well as Nordost Heimdall 2 and Frey 2 interconnects.
The Sigma and Alpha NR are quite the equal of the Nordost Odin line - which I hear at my dealer's (and in my house, if I want to listen).
For power cords, Shunyata is fantastic. Have their speaker cables, too (Python and Cobra), but the Sigma power cords is as good as a Nordost Odin 2, which I played at the same time, in the same room, on the same system. In fact, the Shunyata was at a disadvantage, as it needs "settling time" once you move it around from room to room, or even re-arrange it in your system. (It usually takes about 2 hours). So, with ZERO "settling time," it was every bit the equal of the Nordost Odin 2. And that was the Shunyata NR vs. Odin. I wish the Delta was a ZiTron design, as I'm sure that would lift my system even higher, but I've just listened to the definitive "Girl Group of the '60s" CD, and while I listened (somewhat nonchalantly) and liked it, I never loved it until the Sigma and the Alpha NR were put into it and now I find myself hearing (easily) harmonies and dynamic levels from the background singers that I never noticed before (and if they were THERE to be noticed before, I would've heard that). Vocalists, in particular all had their own, individual voice, so it sounds like a group harmonizing and not at the expense of other instruments in the song, which shone for as rarely before. For the record, I'm using a Schiit Ygdrassil DAC and an Arcam FMJ 23 as transport, with Transparent premium SPDIF digital cable.
After much listening, most of the Nordost has left (I'd have like to have wanted (as in "I- MUST-keep-that!" enthusiasm with the Nordost power cords, but, as "they" say, "I couldn't even..." Except for the Frey 2 and Heimdall 2 interconnects, which I very much like when combined with Shunyata power cords and speaker cable.
All things considered, Shunyata is a Universal cable. I've yet to hear the system it didn't allow to sound like magic, if magic the recording was endowed with.
