Hi, M,
I think you'll really enjoy your new turntable and the Goldring 2400. The Pro-Ject arm's biggest flaw I think is the tonearm mounting post design. It's not a very good fit and subject to misalignment (off-vertical) when you adjust height for SRA. As for cartridges, I've been running a Dynavector DV-20XL cartridge for the past year and it sounds great with the mmf-7. It was a lot of money (for me) to spend on a cartridge but it was worth it. It does involve changing out the stock counterweight for a heavyweight (120g) counterweight, available at http://www.musicdirect.com/product/73925.
I found specs for the Belles 28A and noticed that it has settings for a moving coil cartridge (including variable adjustments in impedance/resistance loading, nice!) but the gain doesn't look right; 26 dB of gain isn't much, unless they figure you'd be using a step-up transformer/headamp with it. I run my 20XL with 50 dB of gain and it seems to perform best with resistance loadings below 100 Ohms. (Based on my experience and numerous threads about this cartridge.) I run mine at 70 Ohms now (started out at 44 Ohms) and it sounds very nice.
I haven't heard the Dynavector 10x5 so can't compare the two, but if you can wait to upgrade cartridges and you can accomodate a LOMC with 0.3 mV of output and 100 or less Ohms resistance, then the extra $300 to get a 20XL might be something to consider. I'd just play the Goldring 2400 for a while and get to know the sound of your system with the new 'table and cartridge. Then you'll have a better idea of what you like and dislike about the 2400 for comparison with other cartridges.
Have fun!
Tom
PS: Another LOMC cartridge to consider is the AT33PTG, which I also like a lot, but I'll note a couple cautions: Namely, it's not a U.S.A. warranted product and it has a tiny stylus that is not easy to see for alignment. That aside, it's a great cartridge for the money.
