Magic Diamond vs Airtight PC1?

Is it true the MD uses a spherical stylus? I read an article somewhere on its very eccentric designer (who also designs some very unusual amp) and just wondered if anyone has more background on him?

..
spherical = conical.
same thing.
that is the DL-103 standard stylus/cantilever.
No design change there ...

Gadfly, OK, so are/were you able to tell what mods if any (other than the body and epoxy potting) have been done to the 103 by Blue Electric?

What's your point? Do you know what they are? If so, tell us. But even so my only point is that the original piece is a DL-103, that can not be denied.

I know that the Zu does a few mods and I am curious to know what kinds of mods would incur 5k, 10, 20k, 30k. That seems to be a bit inflated.

But tell us, convince us, that the mods are worth the money. I am willing to hear you out. Materials cost can't be over $20 so the design work must be unfathomable.

BTW, the 'sound' of the cartridge can not be your argument because I already have that for less than $400.

Yikes! I thought when I originally posted the MD cost $2,500! Looks like I was out by 3K! My apologies.
