Are Bang and Olufsen turntables any good?

What may have oxidized is the suspension in the cartridge and/or the glue that held the stylus. Either one is possible, likely even, over a long period of time.

Lewm is right of course about the diamond stylus itself not oxidizing. Anyone who passed HS Chemistry should know that's impossible. Carbon in its pure crystalline form has no openings in its electron shell for an oxygen atom (or any atom) to bond with. Of course whoever said that may well have oxidized their brain. ;-)

I have owned several B&O turntables over the years. The best was a 4002 (or was it a 4004) with a 20CL cartridge. I remember it sounding as good as some very high end tables with medium priced MC cartridges. I had compared it to Dynavector Karat 23R. That particular 20CL cartridge was really really good sounding and the tonearm and cartridge mass combo was very light. Combining that with linear tracking made it one of my favorites.

I have a Beogram RX2 and just pulled the MMC2 cartridge out and bought adapter for standard mount.I don't like the cueing and the way the arm works on that table at all.I have several Dual 1200's and a Rotel I'd like mount the MMC2 on.I'm not dismantling my Clear audio virtuoso wood off my Rega to hear what it sounds like on the Rega.The MMC2 sounded like it needed a better table than on the RX2.The Rega Clearaudio combo sounds much better.Any thoughts on the quality of RX2 to the Dual's or Rotel with the MMC2?I just got the adapter and haven't mounted it yet.

As others have brought up...the limited use only using B&O carts on B&O tables kind of takes the fun out of it...iI always felt B&O was overpriced related to performace...but if your table functions and the cart is clean...go for it!

they are not great compared to what can be had some similar prices. Technics 1200, Thorens, Rega...

Not a fan of the cartridige mount either, it narrows selection.
