Finally bought a new Turntable!

Hello All,
Well I done did it now, I bought myself a new Turntable.
After much research and talking back and forth on forums, looking at various models, I finally decided on a Mofi Studiodeck with the Hana SL MC Cartridge.
I bought it from a local Hi-Fi shop that gave me a 10% discount on the table and a 15% discount on the cart.
I have only had about a week so far and have not had a chance to play a much music yet. Just a few tracks here and there.
This does bring me to a question that I have for the community.

After initially playing a few tracks, I felt I had to turn up the volume a bit more compared to b4 when playing the same tracks on my Denon DP-300f, which seemed to have a bigger impact at lower volumes.

I had the shop configure my Phono Pre-Amp (Sim Audio 110lp V2) and the gain was set to 60db.

I set it to 66db and RIAA Curve. I think that improved the sound a bit more.
But what I want to know, for the particular cart that I have on the table, what are the other recommended settings?
I know the manufacturer have their suggested settings and ultimately, I probably have to try different settings and play a lot of music until I feel I have found the sweet spot but wanted to ask you all if you have any suggestions or opinions.
One other very specific question that I have is, Does making changes to the phono pre-amp have any negative effects on the system? Meaning, could I potentially do any harm to the system?
I appreciate any feedback.
