I've had the very good fortune of using Pete's low power and high power Digital PCs in my system over the last month. Since this thread is about the high-power version, that's where I'll focus first...
I picked up a very impressive NAD M2 integrated a few months back that I first demoed using a TWL 8+ power cord. Afterward, I tried a few other power cords I'd had and was quite surprised how much of an influence the power cord had on this integrated. Seems that some components respond to power cords more than others and it was clear to me that the TWL 8+ made a very positive difference. I then heard about Pete's new Digital PCs and asked to try them. When I got the high power version on the NAD, I was quite taken by it. Not only was it a great match, but seemed to be a step up from the 8+ as well. After just a few days of listening I told Pete he wasn't getting it back. I guess you could say it does what all of Pete's TWL power cords do... enabling a wonderfully relaxed and well defined musical presentation that's just full of toe-tapping PRAT. The Digital high-power did all that with the NAD yet seemed to add a greater sense of black background contributing to what I feel was a better defined and open soundstage that was just easier to hear into. I don't know what fairy dust Pete uses on these, but it's working for me.
A quick note on the low-power version... I swapped a 10+ TWL power cord that was feeding my Oracle CD transport with the low-power version of the Digital. To be honest, I didn't expect much since this transport has always seemed a bit impervious to changes in power cords. But damn if it didn't take the CD transport up a notch as well in the same manner. Quiet and relaxed but offering up all the dynamic fireworks the CD had available. Perhaps there was a contributing synergy since I tried this while the high-power Digital was on the NAD as well. To be honest, I don't spin CDs much anymore so I really wasn't thinking of buying yet another power cord for that purpose. But damn...
I should add, from an appearance standpoint, these cables are quite stunning... I love these new terminations. And like all TWL cords, they are extremely flexible. The only difference I can see and feel between the high and low power is the gauge of the wire. The high-power is definitely thicker.
Congrats Pete and thank you for the chance to check these out.
