Yes
15 years ago or so I auditioned the Shunyata Anaconda interconnects and speaker cables as an upgrade to my JPS lab superconductor+
(well regarded)
The improvements were so dramatic. I remember thinking if I have to mortgage my house these are not going back.
and they did not go back
about $12,000 at the time which was quite an outlay for me
didn’t regret it for a second
Worth every penny
