Why have the prices of Marantz and Sansui speakers have gone up so much? Whyyyy???

From when I first became aware of good home audio in the late 60s through later years it was always a mystery to me as to why the Japanese made lousy speakers. Including Sansui…I had a large pair of Sansui speakers for a while (left with me by a friend) and they were awful compared to my KLH speakers, or JBLs, Klipsch, AR, Bozak…whatever…just bad speakers, and the Japanese know how to make other things. Weird. Later of course things got better, but I've never forgiven Yamaha for the NS10…I understand why engineers used them, and all of them did, still…it makes me feel creepy just thinking about those things. I have to go lie down and breathe...

 @wolf_garcia were Ns10s so good or that bad? I know the ns 1000s were well regarded

I hated those damn things…screechy crap, but used by everybody.

Vintage audio is a fad right now that seems to be growing. Everybody wants to be a flipper too and price things like they are funding their retirements. People do also collect those terrible sounding speakers because they think 'kabuki' is cool or fun. People fill their garages and shops with the things in stacks.
