Both. The cartridge is intrinsically balanced, so if you replace the cables with two conductor-plus-shield, then use a balanced-input phono stage with a high common-mode rejection, you can get superb real-world noise performance.
One of my favorite demos is turning up my volume control, then touching one of the cartridge pins- everyone instinctively flinches, then relaxes and laughs when they hear no horribly loud buzz/hum. Try that with the conventional single ended setup!

Did you build the phono amp yourself or you have a reccomendation for ready made amp.. or any other option.
also, would you consider an integated chip as optimal component for a good phono amp, or its better to use discrets for best sound?
Yes. My MC preamp is in the Articles section of diyAudio. My MM preamp is in Vol 7 and 8 of Linear Audio. There may be commercial balanced input preamps out there, but if so, they're rare and likely hideously expensive. If you use a moving coil step-up transformer, then (assuming it has good CMR) the conversion to balanced input is really easy.
You can likely do an excellent IC-based balanced phono stage for a reasonable cost and effort- I'd probably look at chips like the THAT1512 or SSM2019.

A few microamps? No, that's nothing even vaguely unhealthy.
I might be a bit wary of noise current for higher impedance (e.g, MM) cartridges, though.
I will be curious to hear about your experience with that, having spent some time messing with an old TD-160.
When the rewire is finished what will you use for a balanced phono preamp? One of SY's designs, or something opamp-based?
Maybe something like this: Husarz - My Photo Gallery
I made it at the beginning of the year:
first stage with ssm2019 + servo >> passive 2122Hz/50kHz and second stage with composite single opamp + LT1010 with active 50/500Hz.

To quote Ben Duncan , a British audio expert: ,,Very small direct current(2microampers) will offset the magnetic material BH curve from its linear region and we can expect an increase in distortion and related maladies, particularly when tracking high level passages,,.
Always is better to avoid any risk.
