@Robson My recommendation, if you already have some ZMF cables that you like, would be to buy a Utopia-mini XLR adapter. I use those on my Utopia 2022.
Even if you still want to buy another cable, trying your OG with both a copper and silver Lektrik will help you decide what you want to get. And any new cable you buy could be terminated in mini-XLR, making it usable for your Utopia and ZMF headphones, so the adapter wouldnāt be a waste of money.
If you do pursue a new cable, then Corpse uses Cardas copper for their Gravedigger so Iām going to guess that the closest from the other boutiques is something made from OCC copper, or mostly OCC copper with a little silver mixed in, if youāre looking for a similar tone. I have a friend who uses a silver DHC Molecule Elite with his Utopia OG because it doesnāt add anything to the sound, but it doesnāt sound like thatās the direction you want to take.
I have an Arctic Cuprum (OCC copper), Gladius (half OCC copper, half OCC copper/silver blend) and Euphoria (lots and lots OCC silver).
The Cuprum was my first foray into premium cables, and I use it with my Stellia. It has a really nice tone IMO.
Iāve compared the Gladius to multiple other cables and it definitely sits in the āsounds like a copper cableā group, as the mids are nice and warm, but the treble is also extended without being bright, and Iām guessing that comes from the copper/silver blend. The Vector that you mentioned sounds like a ābaby Gladiusā.
The Euphora sounds very different from my DHC Molecule Elite (very neutral, neither warm nor bright) and closer to my memory of the Prion4 (still fairly neutral but the extra silver seems to give more body to the mids, without quite tilting the sound to warm).
Arctic doesnāt have sales IMO, which I think is smart for a boutique manufacturer, because it gives them steady cashflow throughout the year, instead of a rush of orders at sale time. I also have cables from Norne and DHC, and I think theyāre all comparable in terms of quality, but the customer service at Arctic is second to none. If you email them with what youāre looking for, theyāll quickly respond with suggestions within your budget. They have a bunch of headphones that they test with, and have always been open with me about how a cable sounds with a particular pair of headphones.
Edit: I forgot to say that Iāll try to remember to bring my adapters and various cables to CAF in a couple of weeks, and Iām hoping to try the cables with an OG while Iām there.
