Magic Diamond vs Airtight PC1?

I made the mistake of listening to Mr Andreoli's "Silver Spirit" cartridge at Lloyd Walker's house. (It's the the "big brother" to his Magic Diamond cartridge.) I'm ruined. As much as I like my Magic Diamond, the Silver Spirit is even better. Too bad I can't afford it at U.S. retail prices. Such is life in this crazy hobby of ours... :-)

I think, "Tondose" can be tranlated with Tone (Ton) and Box (Dose), let's say, Tone is coming out from a little Box.
I am not sure, but I think, Tondose was the name from a very early Cartridge in Germany.

I own a magic diamond and a denon 103 too: both have a conical shaped stylus and the same cantilever

That in and of itself, does not mean that the MD is a modified Denon. Many carts use the same type of stylus configuration and canteliever materials. When you refer to the Magic Diamond's "conical" stylus, I am assuming you mean "spherical"- as that is the actual shape of the stylus.

Slipknot,I cannot thank you enough for the post from Pos Feedback,re:the letter.
Absolutely great stuff!!
BTW,it seems clear that these Magic Diamond products are WAY under the radar,and seeminly intentional!Low volume sales usually means attention to detail.I'm always willing to learn,and surely have done so here,in gaining more perspective.This does not mean that we run out and buy the product,but we can ALWAYS add to our "little inner computer memory"(mine is small),and call on the data at some point down the road.Buying decisions should take many factors into consideration, and at least with me thay certainly do.
Best!
