I would first like to mention that I subscribe to an objectivist mindset when it comes to dynamic transducer amplification. I would be comfortable running any of my headphones out of something like a Magni+Modi or O2/ODAC and have little-to-no interest in upgrading.
However, I have almost no experience with electrostatic transducers besides listening to them at meets. In my brief research it seems that the likes of the KGSS, BHSE, WES et al come up as "the usual suspects" for electrostatic amplifiers. I've also read good things about the SRM-007t and a few older Stax models.
These are all very expensive.
I am wondering if there is a relatively "cheap" (i.e. sub-$500 by any means, including second-hand) reference electrostatic amplifier out there, preferably of Stax Pro bias sockets. By performer I mean by the usual objectivist criterion -- low/inaudible distortion and noise throughout a flat 20Hz-20KHz output frequency response.
