If you had $2500 to spend on a new TT and cart.....what would you buy?

You'll get a lot more value from a used table. Since a cartridge is more of a limited lifespan item, new cart makes more sense unless you're prepared for a rebuild sometime in the near-ish future. 

Maybe some indication of the system this will go into would give a bit of context.  Are you planning for the table/cart sticking around to use with higher end gear down the road? That would make me prioritize highly resolving over convenience, etc. Are multiple tonearms and carts in your gameplan? Cheers,

Same old BS, if there are turntables to avoid then Rega and Pro-Ject are two perfect candidates to avoid in any scenario, especially for $2500 with those awful tonearms and cartridges. Any of them is a ripp-off belt drive technology that can’t even provide a stable rotation and only degrade in time. 

These are all good- I asked because I am deciding and every table mentioned - minus the used suggestions (which are also good ideas that I have considered- but didn't research used tables) were in the running. 

I am leaning towards the Clearaudio Concept table with the MC Concept cartridge- Anybody out there have this table?

@polkalover.. I recommended the Concept turntable and currently have one also but want to first say there are a lot of nice tables in your price range so do your homework and read as many professional reviews as you can. My budget was similar to yours and I would only recommend the table with one of the upgraded tonearms and not go with the standard tonearm offering based on my research and also based on a friend that has the Concept with the standard tonearm. The standard arm is much less user friendly when changing and setting up new cartridges in addition to playback quality.
I went with the Satisfy Carbon tonearm that is two upgrades up but they also have a Satisfy Black tonearm for less that is also a very nice tonearm. Upgrading the tonearm will cost you much less doing it at the time you purchase the table than if you decided to upgrade after the fact. The Music Room website has a good breakdown of upgrade pricing vs standalone tonearm pricing. 
Like I said do your homework as my experience with different tables is limited. I've owned Technics and Music Hall tables and thought they were great tables also. 
With that said I'm very happy with my Concept table so good luck with your search.
