Actually do you know if all those companies make cables only with common connectors, or can they also make a cable with more obscure / proprietary connectiors like Audio-Technica’s A2DC?
The best cable I could find for my headphones is some unknown braided cable from Ebay. It’s robust but very kinky and microphonic, would love to get a better one.
Got my first pair of Grados, the SR80X as a gift to myself. They are awesome. Turns out this sound signature and sharpness of the sound are right up my valley.
