Which cartridge in a Nottingham Analogue?

I live in Southern Spain and the nearest Hi Fi shop is 100Km away so I've found a shop in Berlin, Germany who seems really helpful (I'm travelling to berlin later this year anyway). I have assumed that he will know the technical side of things and will provide me with 3 or 4 decent options based on my preferred sound characteristics.
This is their website for anyone who may be interested what they can offer. My question was to try to understand what his options will give me. http://www.phonophono.de/

I think you have got it absolutely right Mechans, Whilst I have an interest in the technicalities and effect of component change, I really just want to listen to my favourite music without worrying about how to squeeze the smallest difference/improvement out of it. I also don't have the money or storage space (or understanding wife for that matter)to be constantly changing components.
The reason my list is so exhaustive is that my phono amp will run MM, low output MC and High output MC so my choice really is unrestricted.Also, given that I've only previously had MM's, I thought I might try a MC, and possibly a low output as I believe from the research I've done they seem to be slightly more. However, I am open to whatever sound best on the turntable.

FWIW, with a tonearm effective mass of 11.25 gms, which is "medium", you have a wide variety of choices. According to theory, a typical high compliance/low output MC cartridge will work fine in that tonearm but probably not super optimally, which, as you say, you don't care about. The good thing about having a tonearm with a lower effective mass than optimum is that you can quite easily increase effective mass by adding a mass to the headshell. We all "just want to listen" to our favorite music.

Audio-Technica AT-33PTG/II 0.3mV MC Cartridge

I think the Ortofon Black would be superlative...that's what I would do.

In the least you could do what I did and use a medium to high output MC cart. I have a Dynevector 20XH and use a MM phono pre amp. I am sure you get the idea. I think the sound is quite good but the real feinschmeckers will say it doesn't do MC the way the other good MC cartridge do. Ignore these naysayers and consider using one. What is choice of Phono stage, obviously make sure the phono stage has the option for MM which what I put my MC cart through. I use a Graham Gram amp 2 SE which is MM only, if want the option of true low output MC you'll need to pick another phono stage.
