HiDiamond Power cords...

@highstream, sorry for late response, I agree with Ozzy in that the P4 sounds calmer and effortless. I hear an inner delicacy with the P4 than a P3. The P4 is a few stairs up from the P3 in many many ways. But that's why it is what it is and demolishes many other cords 2-3 times it's price.

Out of curiosity have any of you compared the P-4 to the CH Acoustic X-20 power cord?
(I recently received my HD D8 speaker cables, one P-3 and should soon have one pair of 3-XLR interconnects).

Lak, No sorry I have not tried that power cord.

Lak, me neither.....

Currently I am using Audience powerChord e for my tube monoblocks and, planning ahead the upgrade, would anyone suggest that the P3 is better than Audience powerChord SE?

As for HD, having a full loom of CT1E High Fidelity, I miss some of the density I used to hear with PAD Venustas so may try out a pair of D8 speaker cables. In my main system, the HF CT1E digital was way better than the HD digital reference. I never had the D9 IC to compare with the CT1E IC (RCA).
