What turntable in the $2500 range?


I am so confused and I hope I can get some clarity and good advice in picking my next turntable.
At this time I can afford (wife decided budget...) to spend up to $2.5K.
I am using a Parasound ZC ZPhonoXRM (MM/MC) phono preamp, Parasound A51 biamping B&W 802 Nautilus. 
On the new market I am lookng at Rega 6 (Ania MC), MoFi Ultradeck (MC?), Music Hall mmf 7.3
I am listening to almost evrything but I want to start focusing on Jazz, Blues, Irish music, Southern rock (Lynyrd Skynrd, Creedance Clearwater Revival) and some classical as well.
My focus is on soundstage, vocals and details with a warm sound.
Please let me know your thoughts on my choices and feel free to suggest anything else you think it could work, even if it is used.
One more question: why all the above turntable do not allow removable shells? I would like to experiment and try different cartridges like I was doing when I was a teenager...
Thank you for reading the post.

After being demo'd two redesigns vs one which is a original OEM designs on the Tonearm I use. A s subjective evaluation and a recollection of a past experience that is quite indelible, I can state there is merit in considering an improved connection for a Bayonet Type removable head shell and using Wand Wire that is continuous from Cart' Lead Out Pins through to Phon' RCA.

The A/B of the OEM Bayonet Connection for the removable Headshell is undoubtedly quite convenient, but with a design a little less convenient the sonic betterment as a result of the improved rigidity of the Headshell as a redesign proved to be immense, and very very much wanted to be kept in use.

A Later time the Tonearms were compared with a exchange of a signal wire and as a continuous wire within the wand. This double change (wire type and removal of connections)  was substantial as a betterment as well.  

I should added a comment made after the Headshell demo'

Which suggested that as a Bayonet connection to a Cartridges sensitivity, is like the Cart' is attached to Flag in the wing on a Flag Pole.

Crude, but rigidity of the Headshell is a real winner. 

I can't see a well thought out Removable Headshell that is designed to be rigidly coupled to the Wand being too different from a Fixed Headshell.

Differences may be detected through different Headshell Materials

Well I am in NH and don’t have access to my GAE, the cartridges or the headshells up here so I can’t duplicate the results that I am trying to relate from memory.  When my wife and I return to FL in early December I will try to duplicate the tests and post the results so we can have a more fully informed discussion.  I would like to reach agreement with what you both are saying.  

I know you favor multi-arm turntables.  I, on the other hand, have my hands full with one arm per.  Setting my own handicaps aside, this looks to be well ordered kit.  I have set up similar arms and can tell you they are probably good performers.  In all likelihood the turntable itself will be slightly off speed, but not terrible and quite listenable.  Not markedly different from my own VPI HW-19 MkIII.  The plinth looks like a bit of a beast, though, doesn’t it?  Whoever buys it better have plenty of space.  Pro-Ject makes excellent turntables in every way, they have my full respect.
