Need help on cartridge recommendation, under 500.


I've been a long time fan & user of the excellent Audio-Technica AT-ML170 moving mag. cartridge, but...what else, am searching for perhaps more detail & smoother mids?

I'm currently using a Well Tempered "Classic" (latest version) with the outstanding B.A.K. P5 all tube phono stage.

Any & all recommendations for moving coil/magnet under $500. would be greatly appreciated.

Thanks!

used Benz Glider ~$350-450, used Dynavector 20xl or 20xh. always prefere a local pick up with my pocket microscope for these purpouses.
If you want brand new only you can get Grado Sonata MM cartridge with low output, new Dynavector 20xl or 20xh will be a little more than $500.
Direct from Japan for around $600 you can order Dynavector XX1 (not the DV1)...
Dynavector 20x has $525 list price in the US which means that you can find it for less than $500.
I would second the recommendation on the Grado Sonata at $500. Sweet midrange. Musical.
Another vote for the Sonata! Just be careful, as they have a tendancy to pick up motor hum on Linns (the very inner grooves only.) This hum is very minor.
Hey, thanks to all!

A friend of mine also says the clearAudio Aurum Beta (?) is one of the best for under $500.?

Anyone out there heard it?
