HiDiamond Power cords...

Anyone know who sources the carbon-fiber plugs on HiDiamond's upper end gear (specifically the P4)?

My thoughts - upgrade to P4 wherever you can. This provides the foundation for the HiDiamond sound. I realized that the full potential of all their other cables was only really revealed with that P4 foundation. I now have 7 P4's, one to each component, and 2 20A IEC P4's for my 2 Running Springs conditioners. On the Running Springs conditioners, the P4's blew away the vaunted HiZoot Running Springs cords.

I don't think the P4 preferentially improves hi-current components over low current or source devices. Beyond sheer current delivery, the P4 really excels at image solidity, nuance, and low noise. These traits yielded exceptional results with my Cary pre-amp, and Bryston digital components, as well as with my amps. Actually, I equipped my source components with P4's before my amps (which were on P3's) and without a doubt, the impact on the tube preamp and DAC were the most profound of all.

My suggestion is - P4 on highly resolving source components first, then on amps. But that's just with my system. Another option is to get 2 P4's, and try them around before deciding the best spot to start. Whichever way you go, you will quickly come to the realization that you'll need P4's all around!

And don't forget the long burn in. I invested in a Cable Cooker when I realized the path I was heading. It helps, but nothing replaces time.

Jazz, I tried the original LessLoss power cable several years ago, long before my adventures with HiDiamond. I was not impressed, and after a few weeks I sold it. Who knows, maybe I never gave it a chance. I never tried another LessLoss product, so I can't comment on their newer offerings.

The peace that the P4 and other upper range HiDiamond cabling offers is the sense of reaching a goal. I don't doubt there are superior sounding products out there, but at what price of entry? Other than continuing to experiment with my AES/EBU digital links, I feel no urge to try new lines of cable. I'm hoping that peace lasts a while, Lord knows it's taken a while to get here!

By the way, I installed a custom set of 2' jumpers from my Maggie MG20 external crossovers to the panels, made from HiDiamond D5 speaker cable. Really nice complement to the D8 speaker cables.
