Less noise. More open, more musical, more dynamic. Pretty much better in every way. On most songs I couldn’t even tell the difference between delta and alpha. On some songs alpha was maybe more dynamic but the tiny difference made me discouraged by shunyata.
Shunyata PC Shootout
Have some power cables in for testing from the Cable Company:
Alpha XC and Delta XC feeding my PSA PowerPlant. I currently have a Shunyata Venom.
Long and short: both Alpha and Delta are substantially better than venom and have a massive impact on SQ. They increase sound stage by a lot, dynamics, and clarity.
It’s possible the Alpha is too much of a good thing, but I’m only on day two so my opinion may change. It feels the Alpha does the same changes as the Delta, just bigger in all ways.
I would also say the Delta is, say, a 30% improvement in SQ and the Alpha is 10% more improvement.
Regardless, both are a huge improvement in my system—dang, I’ll probably have to buy one.
