I have heard it. Garbage. It doesn’t provide enough gain for a 007 to play above a whisper at max volume (approximately equivalent to the loudness of a Carbon at 9 o’clock with a 50k volume pot). There is also photographic evidence suggesting its output bias line is electrically unsound and unsafe for electrostatic headphones: https://www.head-case.org/forums/topic/786-the-headcase-stax-thread/?do=findComment&comment=778245
