My new 3m long CustomCans (UK company website https://www.customcans.co.uk/ ) HE-6 XLR cable came this morning (didn't expect it to arrive until next week so a great surprise especially arriving on a Saturday for the weekend ) . I also ordered an adapter cable with this new cable so I can plug my HE-6's into my Cypher Labs portable amp. Listening to Moby with this new cable and....oooo wow already a huge difference to the stock HiFiMan HE6 XLR cable i.e. more treble, separation, sound stage and a lovely clean deep bass. And it's not even burnt in yet !. Can't wait until it is fully burnt in.
