Good Luck with the Sale,
I can attest to the fact that Allnic ZL cables are amazing ! I have been using the ZL 5000 on my Pre-amp and two on my Quicksilver mono tube amps. "You don't even notice if the power cords are there "- that is how quite they are, plus they do not impart any kind of their own signature or characteristics - Yes they are expensive
