I still have exactly what I had at the meet, and I'm not planning on getting anything new. Only my Starving Student changed, because it changes every day. This thing is a learning project, and once a week I get to tweak something on it that makes it better. I actually received another hundred dollars worth of parts this week to upgrade it, and they are waiting on the shelf begging to be hacked. Can't wait to try those NOS German tubes...
Concerning the HE-400, it's strange but for me of all the headphones I heard at the meet the HE-400 is the one I remember best. And I didn't even like it, I don't think I would ever buy one. It's heavy, and has a nasty treble spike that kills me. But that bass! Woha what a ride. The cleanest bass I've ever heard out of any headphones. If there was a known way to tame the treble spike that did not touch the bass in any way, I might consider it as a complementary headphone for electronic music.
But still. <3 HD800. It's sad they are so overpriced though.
The price on those Stax is actually quite reasonable. I thought all electrostatics were well into the 4 digits, which was why so little people owned them. I guess I'll have to go read on these, some day.
