If I am being picked, I would use the following equipment for testing:
Headphones: LCD-3 and HD800
Source: Resonessence labs Concero HD
Amp: The Wire Headphone Amp
And YES, I would love to test them!
EDIT: Just want to add that I am a long term HiFiMan supporter. I had in my possession RE0, RE252, RE262, RE272, HE400, and HE500 -- although I have to add that all were sold because I found something better eventually. So it's natural for me to wonder now: Is HE1000 the real deal?
