HiDiamond Power cords...

Kzhtoo, I would start with the P4 on the amp as it's gauge should be better for your amplification. I am awaiting my P4 20 amp to have the 15 amp connector put back on as I had sold my EAD Powermaster 2000(20amp) and now use a Hybrid tube Integrated(15amp). The P3 that was on it will move to my CEC belt drive player. As to the P4, it is a different league than a P3 for sure. I have 3 in my system and I've said in recent posts, my merry-go-round has stopped here......unless HD finds another realm that we aren't aware of.......Happy Listening....

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.

Kzhtoo, I think whichever position you place the P4, when all is said you may have P4's on everything as I do. Your soundstage will expand with greater detail and depth, quieter background, extension and isolation. I couldn't imagine if say a P5 was made what it could achieve more than this cord can......Happy listening.

Thank you for all the info, guys. Second P4 is now on the Pass pre-amp (another P4 is from wall to power regenerator), the improvement is not subtle at all. Feel like a very worthwhile improvement. I ordered a set of D8 speaker cables also and will arrive in about 2 weeks.

Kzhtoo,
Congratulations on the purchase od the D8 speaker cables. Just remember all of the HiDiamond products have a long break in time.
