I really like Synergistic Research Halogram D on PD. I tried Shunyata King Cobra CX and really like the bass but found the midrange and high a bit on the dry side. One PC that was better than SR Halogram D was Stealth. However, Stealth sounds better only when they are quite a few Stealth PCs in the system. When I tried only one Stealth digital PC on PD in the past, I was not impressed but once I added Stealth PC for my mono blocks amps, Stealth on PD made a much better impression, enough that I started slowly to replace SR PC with Stealth for the rest of my system. SR has bigger, heavier bass, bigger sounding, a bit less open and less focus than Stealth. Stealth is a touch leaner but just as punchy, cleaner, more detail.
However, I have not try the new SR power cords that have interchangeable active shielding circuit.
