I did that briefly with the Woo WEE and the SR-007.
I thought about the various electrostatic diaphragm designs of Stax products and which ones were mostly used, which were apparently the Lambda series. According to this review article:
http://kenrockwell.com/audio/stax/sr-lambda-pro.htm
Capitol records got rid of all of their Lambda Pro setups in 2001 for less pricey setups "to be sure mixes sound good on ordinary equipment, not just on the very best equipment." (quoted from the kenrockwell.com link)
For CEntrance's artist's testimony page:
http://centrance.com/artists/
CEntrance bases a whole lot of their engineering on what their artists hear. It is very possible that many of these artists used the equipment Capitol records had, before and after 2001.
I have wondered if any record labels used any of the Omega series setups, because all Omega series setups I used just did not have the right background recording projections for my ears, no matter what DAC or amp was used. It did not have to do with channel imbalance, but on the circular edges of the electrostatic diaphragm emitting different sound projections at the exact same time during more spatial notes and demonstrations from songs. I never heard this from my HE-4 or other orthodyamics, just the Omega series.
Eh, maybe it's just my ears.
