Are Bang and Olufsen turntables any good?

Regarding the "missing stylus"...... That person's stylus wasn't there because they likely used a typical "stylus cleaning solution".....
B&O stylus cannot be cleaned with fluids as they will destroy the bond of the diamond to the cantilever.The ONLY thing that should be used to clean a B&O stylus is BluTac or an equivalent.... Or even those onzow clear spheres of goo......
The supplied cleaning brush is also acceptable, just don't use solution....
I have rebuilt many 4002s and have seen several original carts missing the stylus....because of the cleaning fluid most users think is okay... 

I was a factory rep for B&O right before that model came out.  B&O tables at that level properly set up certainly won't hurt your records.  The cartridge was pretty good, they tracked okay, and they were pretty well isolated.  All B&O products back then were really very "average" sounding hi-fi products; it was the greatly enhanced cosmetics, industrial design, user features, and mostly the exclusivity that commanded the premium price.

Girls just love B&O for the industrial design.  Christmas 1979 I gave my girlfriend a B&O 1900 turntable.  She was so overwhelmed and happy she wept.  

Have to say.... The 4002's I have restored and sold always make the buyer gasp when they see it. Truly elegant design....
Just upgraded my 4002's cartridge from the MMC20EN to the MMC20CL.
Wow! I did not think this turntable could be improved upon but I was wrong. More detail, channel separation, bigger sound stage... Hearing detail I had not heard before, even with the 20EN.
Just incredible....
