I am pleased to see that this review has been posted at the Stereophile web site.
The Super Pas Three remained on their Class C rating list for a couple of years, and then was removed because, "they had not listened to it for some time.".
I wrote to them reminding them that the preamp belonged to them, I had installed the Super Pas Three circuit set in a stock unit they had supplied. Thus I suggested that they find it in the closet again, dust it off and listen to it again. They never responded.
The Super Pas Three both kit and factory wired, remains in production now, over 15 years after it was designed. A nice improvement available now is is the Insight output buffer board ($250 factory installed only) that turns the performance up a couple of classes.
