Where do you go to from Nottingham Analogue ?

You don't state which model you have so if you like the NA sound you can move up the model chain. What accessories do you have? Sonic quality is improved with the wave mechanic. Another option would be to upgrade your cartridge. I have a NA Spacedeck. IMHO you could spend more money and get a different turntable but how much better the sound be? It may not be better at all just different. Nottingham Turntables are so well built and designed. I bought mine from a gentleman that upgraded to a VPI classic. When I last spoke with him he said he missed his Spacedeck.

Yes yes, I have Spacedeck/Spacearm too. My question was what do you upgrade to from Dias and Anna Log models. Nottingham also has a $30k something model, but I didn't think about it.
The thread is about turntables, not tonearms and cartridges, let's stick to it.
Spacedeck has a special musicality to it that VPI doesn't.

It's hard to ignore the arm with your question because my Spacedeck/Spacearm ownership was ruined because of their arm. I found the arm wiring poor quality and it was so thin that even some very well respected dealers/repair shops wouldn't touch it for a minor repair. Perhaps if I had a different arm I would have kept it longer. 
For its price the table sounded good, looked great and I admit there is something cool about having to manually push the platter with my finger to get it spinning. But the hassles with the arm and lack of repeatable VTA adjustment are downsides. It didn't come close to the sound and performance that I've enjoyed for years with a VPI TNT6HR that replaced it. 
Also note that Tom Fletcher the brains and heart of Nottingham has passed on, and I believe his main protege is running the Pear Audio brand now. Don't know if Nottingham is even in business. Cheers,

+1 for the TW Acustic as an addition to your list. If the lower cost Kronos makes the budget, that might be another one. Their initial model really impressed me! Cheers,

I never heard before the complaint about Nottingham arm wiring, except that installing the cartridge does require skill and very steady hand, yes, very thin wires. If I could I would have it rewired with Purist Audio wire, but I believe the wiring is quite good as it is. This arm won't work well with heavy low complience cartridges, sure.
But let's return to the tables. TW ? German battery powered ?
