I used the Denon AH-2000 for almost four years before the cable started crackling and the left side sometimes dropping out completely. The hi-fi guys said the repair would be a new cable, which would cost a whole $200 (!), but theese are really that good, I am considering to get them fixed. I bought mine new for around $500, and never looked back. I also have Adam A7’s, and I found the Denons to be super helpful when working on details and deeper bass sounds
