Cool story, bro.. we're here to discuss the HE-400. There's a 'sound science' subforum you can take this argument to.. cause you know, burn-in debates just doesn't come up enough . Unless of course, you're trying to get this thread locked or yourself banned.
The HE-500 I owned was the latest rev. that was available around April 2012. My pair came with the silver cables (terminated to a 3.5mm plug). I had shorter, custom silver cables made for the HE-500, as well. I terminated the stock (silver cable) to speaker plugs so I could drive it from a speaker amp. My HE-500 had the silver cabling (that the stock cable was made of) in the housing which connected the coax plugs to the planar drivers. As far as I knew, it had the newer/newest velour pads. In my estimation, they're identical to the velour pads that came with my HE-400 just yesterday.
