Magic Diamond vs Airtight PC1?

OK Nsgarch - I'll bite: What is a Tondose?

The Virus cart's underside is a bilious green color, just as the MD Blue's is blue. So- I guess it's "virus green" Kind of like the van den Hul "Frog"....

Slip. I admit I don't know what the word "Tondose" actually means, however there is/was and EMT tonearm called the "Tondose" that accepted an integral cartridge/headshell with a different pin layout than the SME, etc. Apparently Micromagic makes a unit for that tonearm which you can see at the bottom of this page:

In Germany, cartridges are even sometimes called “Tondose”. So the Germans know by experience that a cartridge body makes its own “Ton” or sound. (from vdH website)

OK, I get it. Seeing as though the Ortofon SPU is an integral Headshell/Cart combination, I guess it makes sense that Mr. Andreoli would have christened his with that moniker...

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.
