I stumbled across the Stanyan record label site http://www.stanyanhouse.com/stanyanhouse.asp and wanted to share it as they offer the Heins Hoffman-Richter SQ encoded electronic classic: "Music to Freak Your Friends and Break Your Lease" brand new.
I ordered one just to be sure before posting. Sure enough, it is labeled as SQ and when I play it through my Tate it encodes perfectly. I am guessing that it is old stock for I can't imagine the original pressing having sold out given the weirdness of the music. I'm not sure what other albums on the site may or may not be quad. They DO have what seems to be every album that Rod McKuen ever made (for some reason, I was under the impression that he released a few quad L.P.s). Also they sell CDs, some of which I know were originally released in SQ in the L.P. format (I'll list these titles in the matrix cd section).
