New Head-Fier
Sorry I misread it haha, I can tell you about Forza cable but they're in EU
What price range are you comfortable with for this cable? Is it balanced? Single-ended? Would you need it to do both?
All those answers would help formulate an answer.
Regardless, you'd have to comb through earlier posts here for pictures of the narrow/body 3.5mm cable jacks that are thin and long enough to work with this headphone (ie, that can evade the cable-locking mechanism). More than likely any cable vendor you go to either won't be aware of the D8000's internal jack construction; or won't have suitable jacks on hand (but can get them).
I have such cables--actually a pair of 6" connector cables that allow me to use Audeze/ZMF style balanced cables with this headphone. But those come from an EU vendor.
Toxic Cables in UK has nice locking plugs that fit perfectly. He a nice guy too, nice cables.
If in the US, Norne and Arctic are 2 that I would highly recommend BUT........they have a long wait time due to high demand, so patience is necessary.
Arctic has a slightly better advantage in terms of communication as Norne has been known to accidentally miss replies as he is a 1 man show as opposed to Arctic who are a duo hahaha
Another vendor that I'd highly recommend is AudioEnvy for their ToneKraft cable. But they are relatively unknown as opposed to the above 2. Though there is a review here that commends it and is regarded to be as good as the Final Silver cable for the D8k.
I had both and they are comparable in terms of sonic signature.
Before I moved on I wanted to thank everyone for their suggestions! I ended up finding who I want to go with, they aren't US based but their work is truly amazing so I plan on going with them anyways haha. Skedra from Viking Weave Cables is who I ended up deciding on.
