500+ Head-Fier
I have quite a few cables from different brands. I would place the Grand Silver Palladium as one of the best I have, definitely for the price. Arctic also makes great cables, but they are much more expensive.Tbf if you are into cables and expect them to change the sound signature, I advice to look for a studio with a decade or so of research in this segment. There some really talented guys who spent a lot of time with cables and cables only. ZMF is a headphone company imho. To me the ZMF cables are first and foremost a cosmetic thing (and a beautiful one) and are mostly rather random in their overall sonic signature and argueably very similar.
My dream cable would be a Chord Music headphone cable, but they don't make one. I have a few of their xlr and bnc cables, and they are the best I have ever used.
