They just posted what they actually do to the driver diaphragm in this modification. To me, it explains the bad distortion.

"But it’s not the technological improvements that matter most, it’s the Alpha Prime’s ability to connect to the music.  No matter what genre, Alpha Prime will just pull you into it’s silky-smooth and really immersive soundscape.  This is a headphone we hope will connect listeners to their music, and maybe stay up all night rediscovering old treasures."

What the fuck does this mean?  Sounds like pono talk.

Also note the misuse of 'it's' in the second sentence.

Any chance I can get in on the tour for the Alpha Primes? 

I have the Oppo PM-1's headed my way via Oppo sponsored tour and would love to compare it to the Alpha Primes.  Then the only ones left on my list before my decision and purchase would then be HE-560 and Paradox - only if I could get  loaner pairs of these as well... still looking for a source.

I am located in Austin, Texas.

Heard this today at OJs. Jebus! Something is really wrong with these cans. Lean as hell. No resolution at all. Strings are completely wrong. Absolutely no air. Plain weird sounding. Horrible. Worst can I've heard from Dan.

Ultrasones and TH500RP stock at the meet actually murdered this one. Not exaggerating.

Did you take any measurements? I emailed Dan about possibly sending this pair to him to check again. Haven't heard back from him yet though.

If you did take measurements, would you mind if I shared the measurements with Dan just so I can back up my comment to him that these still sounded really weird. Strings sounded tonally off to me as well. It's like everybody was playing with nasally sounding instruments.

I suppose I'm asking Marv as well. Didn't want to share your work without permission.
