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.

I have owned a Technics 1500C, thought it was a bit of a tank and the queing was abysmal. Deal breaker for me but a decent TT.

I want to thank you all for this beautiful conversation. I learned that a fixed headshell is an improvement, now it clearly make sense to me. Maybe I should keep my cheap old TT and have some fun changing cartridges and go with the VPI route and discover a new world.
What cartdridge would you suggest for a VPI with a JMW arm?
I live in the Atlanta area and I am wondering if anybody has a setup that I could listen to it, at the end of the day it is also about our ears and what we like.

@joby15200 I recommend you contact @rpeluso and inquire about his friend's 1300C.  That could be just the ticket for you.  That is a terrific TT.

I’ve used a Sumiko Blue Point Evo 3 and a Soundsmith Carmen 2. With the Carmen I had to add a weight to the top of the head shell available for about $5 on EBay.  The Sumiko was excellent maybe more top end but overall the Soundsmith was smoother top to bottom but then again it’s almost double the price. Both cartridges bought here gently used.
