My recommendation would be to mount your original cartridge first to get an idea of what the new TT sounds with a cartridge you know well. That will give you a good feel for what you want out of an upgrade. fwiw I have heard the Zyx Airy and Omega in the same system and thought the Omega a substantive upgrade - much more musical and fluid, the Airy was quite grainy by comparison.
I am not familiar with these turntables, so I thought I could at least take a look at their website. Impressive and interesting, they make both belt-drive and direct-drive tables.
They recommend optional tube power supply, why not start there? You want your new table to perform its best.
And I agree with Dover's approach.
There are probably a few excellent and quite different cartridges that would work very well, you would just have to take your best guess depending on your preferences.
You could also ask Brinkmann for their opinion, they might be right.
Look forward to your posts about the sound you get out of your rig.
