I just picked up the Phoenix PSU mentioned towards the top of the thread for my Nottingham Ace Spacedeck. I set the speed using a Kab strobe, and I am very happy with my purchase. While not a "night and day" difference there is a palpable improvement in all of the typical areas that everyone touts with a stable power supply: bass, PRAT, noise floor, and fine detail retrieval. They do work.
