I had a PFR-1 pre when it first came out, sold after a few years for a Hovland, then re-purchased one for my BR system about 5 years ago and have not looked back. It was Stereopjile Class A in its time (FWIW) and still is an excellent performer. I have seen used ones on "Gon for less than $1000, which buys you a top flight SS pre that sounds great and is very versatile.
