Tyll offered to measure electrostatic headphones since the STAX mafia donated a custom reference amplifier for him. I sent my SR-207 in and I just got it back today with the measurements included. They look extremely similar, if not better, than his previously measured SR-507. Why would anyone waste their money on the SR-507, which costs $535 more from STAX USA?
