Speaking as an old-timer, his first store was that walk-up but it was on Lexington Ave. between 34th and 33rd. From there, he went to a store front operation on 33rd between Lex and 3rd.

Thanks for the correction Kal. I remembered, albeit faintly, Andy's store being between 33rd and 34th. I'm not sure I remember the second location.
I do remember hearing some pretty awesome systems in those days at Andys. One was a system consisting of Acoustat 2+2s, ARC preamp, Linn table and I think a Hafler amp. The imaging and resolution was for that day, simply spectacular.
