I talked with Tasso few months ago. He runs an add in the paper occasionally listing used, vintage equipment. His clinic is on Carson St and I think that's where he keeps his vintage gear, but the hours are limited. Did Tasso also have a store in East Liberty in the late 1970s/early 80s? If it wasn't his, that place was another amazing audio experience. I first heard both real digital and surround sound there and remember it like the article described Tassos and his store Downtown.
