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).
