What were the prices of early high-quality phonographs? I'm not sure how to identify these, but in 1915 (say) what was the finest reproducer and what did it cost? Let's say, one for cylinders and another for discs. What was the price of the Edison Laboratory Diamond Disc machine? (I've heard $200.) Of the Victor Credenza? You see what I'm getting at. Also, I've heard tell of a "Carnegie Phonograph", a late-Thirties electrical console of some magnificence that's said to have cost $5000 or so. Does anyone know about it? Finally, how much were the most expensive records? Thanks, all. clark
