Looking for a new cartridge (and maybe phono stage) for my Rega RB808

Hello Agoners! I have a conundrum that I’m hoping you can help me resolve. I’ve owned a Rega P3 for a number of years now, which has seen several modifications...each of which has improved the listening experience to various degrees. I’m now at a place where I’d like to step up to a more exotic cartridge and have narrowed down my choices to a small handful. This is where I need some advice!

:)

The P3 has turned into something else over the years. Its got a Groovetracer Reference subplatter, the Rega 24v motor, and...most recently a RB808 tonearm. Prior to the new tonearm I was using an Incognito-wired RB300 with a Benz Micro MC Silver.

My phono stage (currently) is a modified Acurus P10. A while back I had it upgraded with an external PSU, chunkier rectifier diodes, and several capacitors replaced with more exotic versions (Black Gate, Elna SILMIC). These little modifications made a noticeable improvement and I’ve been happy with this phono stage. I’m not wedded to it though, and replacing it may open up my choices of cartridge. It’s gain setting tops out at 57db. So any suggestions for a good MC preamp are welcome.

These are the carts I’m considering:

*Benz Glider (with MicroRidge stylus)
Hana SL
Shelter 501

*I’ve wanted one of these for a long time, but it’s been discontinued and maybe a newer design is better”?

Where I start to gloss over is when I start reading about compliance and effective tonearm mass, etc. I think my RB808 has a mass of 10g. That being said...are any of these cartridges off the menu? I will greatly value the community’s input!
