You can read much discussion about the merits of the MANY different Senn cables available at head-fi.org. (Sorry about your wallet.)
Senn 650 replacement cable
Im in the market for a better cable than the stock cable for the 650. Ive been reading about the ALO Audio braided senn cable and wondering if anyone has thoughts on the vampire wire cable? Musical, air, articulate and a few notches better then the stock cable are important. I owned the Cardas cable a few years back with 600s and loved it. BUt my research reveals its not that far better then the stock 650 cable. Anyway, Im interested in thoughts.. I use a digital music server to DAc to headphone amp.. thanks in advance.
