Well, my HE-5 will be shipped this coming Tuesday. I was able to listen to one yesterday on my setup and have determined that I don't have the amp to adequately power them and really don't want to spend $420 for the EF5 or purchase a different amp that can. I prefer the D7000 but know it's a long shot, so the D5000 in great condition will do.
I would also be interested in the Beyerdynamic Darth Beyers as well.
PM if you're interest in a trade. Otherwise, I'll be changing the post to FS.
