@vinny55 Are you looking for some nice cartridge or what ?
If so, then it's the most exotic way to ask for advice
It's impossible to answer your question because the choic of cartridges in your list is very strange.
Anyway, you can find a lot of good things about Signet cartridges here on audiogon.
Younger version of Raul swear by Sonus Dimension 5, i wish i could find one.
Nagaoka MP-50 is a prototype of the latest MP-500, also many good feedbacks here. You can find old Nagaoka under Jewelton brand sometimes.
Some of my MC and HOMC cartridges manufactured by Exel (OEM) and they are very good, but don't know anything about the model you have mentioned.
I remember ADC Astrion with sapphire cantilever, it's beautiful
under my macro lens. But i'm skeptical about ADC perforance level.

One of the Ortofon MM was highly regarded when the MM discussion was hot in Raul's thread many years ago. It was ortofon M20FL Super (with FineLine diamond). This particular model is very good and not expensive. FineLine stylus is great, i have one NOS
Tried several SPU models on
Thomas Schick tonearm designed for this cartridge. So ellegant by the look, but later when i found SPU Royal G mkII with its
Replicant-100 stylus i was much more impressed! Still have it, the last arm for this cart was Lustre GST-801 with ring weight and heavy counterweight. Now i got my FR-64fx and i'm gonna try my SPU Royal G mkII on it soon.
I can not comment on the rest of the carts, but there are several models of Audioquest i wish to know more about. As for the Shure look for Ultra-500 if you want the best one.
