Chris and I conspired with Al to put on a "to the death" battle royale of electrostat headphones. Electrostatic headphones in attendance were Stax O2mk1, 4070, Lambda Signature, Lambda Pro, SRX3/mk2, Sennheiser HE90s, Koss ESP950, and Beyer ET1000s, plus Sennheiser HD800s to act as a baseline. For amps, we had Headamp Blue Hawaii and KGSS, plus Stax SRM1/mk2 and Vlad's Beta 22 powering a modified Stax SRD7ta. The control amp was the Headamp GS-X. The source for the blue hawaii was the Denon 2900ta (balanced). Sourcing everything else was Dreadhead's dac comparator setup.
Vlad, Hirsch, cetoole, dreadhead, Dusty Chalk, rugby and I were in attendance, with a brief appearance from our benefactor, Mrs. Dreadhead.
A good time was had by most. Pictures to follow, including the obligatory blurry beta 22 photo.
