Just picked up my "new" (one-owner!) Concept 16.5 today - more about that later; need to get back so I can take some photos to post - but let's just say I am very happy! The Concept series of equipment was a house brand of Pacific Stereo. Not really knowing the number of PS locations or where they were located outside California, does anyone have a feel for how rare the 16.5 really is, either in terms of original sales volume, market share or currently surviving units? I have an automatic subcription for the 16.5 over at a certain listing service, and I receive emails much less than once a month for a unit up for sale (There was also one at Santa Clara CL this week), suggesting that they are at least somewhat hard to come by. I don't expect anyone to have any hard numbers, but it would be interesting to hear your opinions on its rarity relative to some of it peer group 160-200 WPC SS receivers such as: Yamaha 3020 Marantz 2385 Sansui G9K Pioneer SX-1280 etc.
