Bob: You'd be surprised at the number of fairly rare vintage audio components which come through Innovative Audio. There was a run of Pioneer SX-1980 receivers from 2014 (when I bought mine at IA) until about a 1 1/2 years ago. I've seen a couple of the big Sansui G-33000 receivers come through the store and one was being sold for $14 K CAD four years ago.
