Audio Technica AT33EV different versions? On RP6?


I was thinking of trying a low output MC on my new rega RP6. The Audio Technica AT33EV looks like a potentially good one that will not break the bank.

Does anyone know if there are different versions out or NOS being sold between these multiple price points:

Amazon - $351
http://www.amazon.com/Audio-Technica-AT33EV-Moving-Cartridge/dp/B001J2KGDY

J&R - $500
http://www.jr.com/audiotechnica/pe/AT_AT33EV/#productTabDetails (some good reviews here)

Needle Doctor - $589
http://www.needledoctor.com/Audio-Technica-Cartridge-AT33EV?sc=2&category=363

Should I check for serial numbers, production dates or something else?

Has anyone tried this cartridge on rega arms, specifically the RP6 arm / table? Do people consider it a excellent, good or poor match? I've been told rega arms like high compliance carts and the AT33EV seems to be in the middle of that range. I would be using it with my Jasmine LP 2.0 mkII phono preamp. It looks like it comes with a nice protective stylus guart like the 95E or my current cart, the Ortofon MC-3 turbo.

Looking forward to see what people have to say about this combo. TIA.

Dear Sbrownnw: Yes, I can attest that 2juki is a trusty seller as Audiocubes2 but this one is always more expensive As other posted Amazon is an additional alternative for the same cartridge.

Regards and enjoy the musiuc,

Just ordered an AT33PTGII earlier this week from 2juki. Seems quite professional and cannot wait to try it out. :)
Sbrownnw,

When you get the AT33PTGII and have it up and running, please post your thoughts on it, and what arm and phono stage you are using with it. I'm somewhat interested in this cartridge too, and also in how your transaction with 2juki went. I was almost ready to order a Nagaoki MP-500 from Japan when I saw this thread, so I'll hold off for now to see what your thoughts are. Thanks.
My system is detailed on my system page and in my threads. I can answer any specific questions you have.
I love my AT33PTG. If the PTGII maintains the sound and build quality -- and the specs read like a great improvement -- then it's an incredible bargain at these prices.
