Cartridge upgrade


I've currently got the following:
B&W 805D
Marantz SR7005 Receiver (setup as pre-amp)
2-Rotel RMB 1090 (bi-amped)
Moon .5 CD Player
Music hall MMF 2.2 le with musichall tracker cartridge and project tonearm. (Turntable has factory tonearm and cartridge)

I'm new to vinyl (9 months) and am considering upgrading my cartridge to a Dynavector 10x5. I guess I want to know if upgrading the cartridge is worth the expense and if so, what will the upgrade I'm considering do?
I enjoy listening to vinyl but it seems a bit lacking in something but I can't place what is missing.

You need a separate phono preamp.
You do not mention any phono pre, so i assume? you must have a phono in the Marantz.
A modern receiver with a phono is using only the cheapest op amp for a phono section!
Buy a real phono preamp and you will get way more from that than any other change.
Clearaudio Nano $350.
Vincent PHO-8 $360 My recommendation.
I agree with the phono-pre suggestion as well, you should hear an immeadiate improvment.
