SOLD: one Oehlbach cable for Sennheiser HD580/600/650 from Meier Audio.
This cable is about one month old, in as-new condition. I bought it directly from Meier Audio.
There's been a bit of discussion in the Cables forum lately about the merits of this cable; I think it provides a moderate improvement over the stock cable, at a correspondingly moderate price. I like it, but it must go to fund more purchases.
