@optimize Paul may not be a brilliant electronics engineer, but he has been able to attract strong talent and build a successful high-end audio company with some longevity. There are very few independent US hifi companies that have been as successful.
I've only owned a couple PS Audio products (Powerplant 3 and now Powerplant 12), but I have a lot of respect for the company and I think Paul and his son have managed their business very well.
