Replace 2M Black or new phono?

Hi,
newbie here 
Less than a year ago I upgraded my old turntable to new Pro-Ject 6 Perspex SB table with Ortofon 2M Black cartridge. Additionally I bought Pro-Ject Tube Box DS2 phono preamp. 
However, after using them for few months, I tried switch from Tube Box to my integrated amp phono section (Yamaha A-S2100) and really it wasn't so much drastic better or worse result. So I sold phono preamp. However, I began to think maybe with additional cash on the hand, I could sell 2M Black and get in MC cartridges category.... 
Because yes, 2M Black is nice cartridge, and it was big improvement and difference in sound quality from my old Audio Technika AT95E cartridge. However, no offence, just 2M Black is not suited for my perception of cheerful sound. It's very detailed, very "scientific" - ideal reviewers cartridge 

So, my dilema is - what to buy first: cartridge or new phono preamp. However, I got dealer which has AudioTechnica / Ortofon / Denon / Grado / Nagaoka and I can get them cheaper, and sometimes even test-drive.
And with phono preamps is harder, my dealer sells only Pro-Ject and Rega (which both I don't like). So I was reading good reviews, and thinking about Primare R32 phono, which I could buy only online and without listening in my system.
However, if my Yamaha A-S2100 MC integrated phono section is capable to drive and give at least 40-50% of cartridges capabilities - I would take that sound experiment. At the moment I would say, that I'm looking for a different sound signature, not absolute quality.

My cartridges shortlist:
- AT33PTG/II 
- AT33EV 
- AT-OC9ML/II 
- DL-103 or DL-103R 
- Quintet Blue

What's your thoughts? Maybe someone made similar moves or have more educated opinion than me?

My system, if matters:
- Yamaha A-S2100 amplifier
- Yamaha CD-S2100 CD/SACD player
- Pro-Ject 6 Perspex SB turntable with carbon 9 cc Evolution tonearm
- Spatial Hologram M4 Turbo S speakers
- QED Xt40 speaker cables / QED Reference Audio 40 RCA & XLR interconnects
