Hi,
I'd like 40mm or so, closed, slim, folding flat-ish, replaceable cable, mid-impedance (150 ohm), 106dB efficiency or better. ...and around US$300 ish.......and of course, very neutral sound quality......I'm not fussy eh ? Cans like this are pretty thin on the ground.....
BTW I have HD650 re-cabled with cryo-treated cable. Oh, and a pair of Klipsch RF-52.....
If I'm a good boy, will Santa be able to reward me with these this Christmas (or sooner...) ?
Cheers
