Cartridge advice

For ’12 inch tonearm this "SP" (Special) version is a killer.
XSV/3000SP compliance is 15cu at 10Hz, and this is the only Pickering top of the line cartridge with lowered compliance for modern tonearms, the rest of them are twice as much in compliance. For $400-500 NOS it is a steal! Stereohedron diamond tip (long life for over 1000 hrs). Try vintage MM - they are the best for the money and outperform almost everything twice the price. Higher models (XSV/5000 or low impedance XLZ/4500 and XZL/7500) for lighter tonearms are even better. 

Luminaries. The word you were looking for, isochronism. 

I'm using a Carmen with the VPI Aries Scout and enjoy it greatly. I did have to purchase extra weight to add to the headshell but they are available for about $10 shipped on eBay.

Miller, you've shown me the light. 

I would want to move up to an advanced stylus shape: microline, stereohedron, shibata, sas.

many of those mentioned above are elliptical stylus, less contact surface, ....

and I stick with Moving Magnet, high enough output.
and, user replaceable stylus

new audio technica offer their ML microline shape, and now have alternate Shibata shapes.

I put a new SAS stylus from Jico into my old Shure V15vxmr body.

I like the brush feature of the Shures. The Pickering recommended by Chackster has stereohedron tip and brush. The brush can be left up, play, then put it down/adjust tracking, play, hear any difference? if not, use the brush, it's a shock absorber, anti-static, duster.
