Much better MM cartridge than Shure V15 IV?


Hi, I have a Pro-ject 2 Xperience turntable, and I'm running a Shure V15 IV with Jico SAS stylus on it. I'm wondering how much higher quality MM cartridge can I attach to the carbon Pro-ject 9cc arm without exceeding the capabilities of the turntable/arm combination? Grados tend to hum on this deck unless I shield the motor's EMF. I have not tried anything else yet. What would you suggest as a clear significant cartridge upgrade?

My bad...didn't realise amp takes mm only...so audiofeil suggestion of phono pre is s good one...opens up other options...
You're already there,save your money or stick in Red Kettle if you just want to be rid of it.
It's good to get opinions as to the wisdom of further investment. I was wondering how close I am to diminishing returns and you guys have helped clarify that. The phono amp investment seems to be a path I can take. I like this system a lot, so maybe pristine vinyl purchases might be a better investment!

Stirling has recently released AB-2 bass units to match their LS3/5as. They are not yet available in the US but can be ordered from the UK. That might be a reasonably sensible way to increase the scale of my sound in my smallish listening room?
Good idea...get a few hi grade vinyl releases before anything major...a tube phono pre would be nice addition...the more I think of it...there is nothing blaringly wrong with your system...a sub would add oomph but dont expect miracles
