I am taking my DX1000 with me in my grave, they sometimes hangs for months without use, but I always return to them..
Maybe JVC is to honest to claim they have done something new and spetacular to their drivers, the truth is that there really has not happend much the last 20 years, if there had happend something groundbreaking in the teknologi a 10 year old headphone would sound terrible..
Just try sit down and watch a VHS tape on your big screen TV a lot of breakthroughs have been done in the visual tekonologi, but a 25 year old headphone still sounds good, there is a resaon for that...
