You said "Lessloss is an excellent value cord, but misses in the bass and image specificity."
What do you mean by "misses"? The primary and dominant function of the DFPCs is to prevent HF noise from entering your gear and causing intermodulation distortion. Assuming this is what the PC actually does, because it's activity is passive in the sense that it merely removes distortion-causing noise, it's hard to imagine the PC "missing" anything. It seems more likely to conclude that the deficiency of bass and transparency is therefore a normal function of the components in question, not some error on behalf of the DFPC(s).
