To get back to Dave's Fisher post...
I sold a lot of my best Fisher stuff to Al "The Fisher Doc" Pugliese of Staten Island NYC. He's said that Avery Fisher realized by around '67-68 that the Japanese were going to eat their lunch, starting with Sony and TVs initially. The cost of converting the entire Fisher line to SS in the mid '60s was so draining to the small-scale company that it made it inevitable. Also his interests lay more with the development of Lincoln Center at that time, and Japanese scale and engineering in electronics manufacturing was affecting all of the small US firms like HHScott (sold to Emerson), Marantz (sold initially to SuperScope, then D&M), even McIntosh (sold to Clarion, then D&M, then an Italian hi-end Co, finally a Mgmt buyout returning it to US control). Harman-Kardon remained US owned longest, but Harman International was finally sold to Samsung :-(( a few years ago. Many other legacy makers are now defunct, for various reasons...
