Just thought I'd update my own thread--I never got to hear any Rev 1's, but my wife & I spent the Christmas holidays in Santa Monica. I hoped to audition the LCD-2 while there, but found out that the Audeze dealer had closed.
Alex, one of the owners of Audeze, got in touch with me and brought his portable setup to our hotel for me to play with, as he was in the vicinity (fabulous customer service!!). I quickly fell in love with the LCD2's, and was so impressed with his portable ALO amp, I quickly decided my first amp would be a portable so that I could take the rig on trips.
Then my lovely wife surprised me by getting me a pair of LCD2's and the ALO Continental Mk2 portable tubed amp; they amp & headphones just arrived today!!
