I auditioned Shunyata NR power cords in March 2019 - both Alpha and Delta versions from The Cable Co. Based on notes made during the trial, the Alpha, more so than the Delta, went through a series of changes despite Shunyata’s KPIP tech and The Cable Co.’s pre-delivery run in.
Out of the box, the Alpha NR did not sound good and I preferred the Delta NR power cord to it. The Delta NR sounded good almost immediately though perhaps not all that much improved over a Venom HC I’d been using. The Alpha went from initially dark and rolled off, to too bright with little mid-range until it finally settled after ~100 hrs. At this time, imaging, resolution and soundstage were improved over both the Delta and the Venom HC cords that had been used on the same power amp
The Alpha and Delta cords were returned to The Cable Co. and a Delta NR cord was purchased from them. Later, a used Alpha NR came up for sale on A’gon and I bought it. This used Alpha pc required only about 20 hours of music playing to come alive. Notes from this point: "...[music] really pops - depth, soundstage, vibrancy."
I have the Alpha NR powering up the various amps I run. The Delta NR powers an eTP60 to which various analog pieces are connected.
Hope this helps.
