Had a chance to stop by ZMF HQ today! I had mentioned to Zach a while back that I’d be curious to check out a newer version of his OFC cable he was developing, as the current version for my length was a bit stiff and unwieldy. He sent me home today with a copper and a silver plated sample!
Plugging in the copper one first with my atrium koa (beautiful color match too) and am pretty startled how more open sounding it is than the black OFC and even my audiophile ninja - those both sound more closed in and narrow in comparison.
Build quality is excellent - nice tight braid, super flexible as it is an unshielded cable, excellent connectors with the right side marked with a red release button, and a beautiful ZMF splitter. Absolutely zero microphonics!
I told Zach that I truly don’t believe that a shield is necessary in a headphone cable, and am happy he has found a quality wire and design for what most likely will be a very reasonable price (of which he will finalize and post pretty soon I believe).
