Hi Zd542 and Guidocorona,
The tonality/harmonics are not what I like to hear. I would call the sound thin. There is definitely something lacking. Maybe it's just my system.
I have been using DIY Furutech PCs, ICs and digital cables in my system, on and off -- not in series. But I have experimented with series cabling in the past. Since the Furutech wire is OCC cryo-ed copper, just like Shunyata cables, I figured the synergy might be good. So, I tried the Shunyata digital and IC cables in series with my Furutechs. Wow! Stunning. So, I tried my PCs with the Shunyatas. Equally stunning.
How does this work? Since I run AES/XLR it's easy. Just piggy-back the cables. With PCs I use a burn-in adapter. Which cable goes downstream? Ah, there's the rub. It depends on which sounds better. This part is all trial and error.
