For me, I went first with FX850, loved it so much and took a leap of faith and bought FX1100. After extensive comparison, I sold FX850 because I felt FX1100 was a worthy upgrade to FX850 and never looked back.
Make sure you listen to both to decide on your own, some people do not like the signature and sold both.
The cable is different and part of the tuning that makes FX1100 so lush and organic.
I swapped cables to see the impact of the sq and felt FX850 sq improved (not by much, mind you).
If you do make up your mind to own JVC FX series, let's start with the budget and go from there.
Of course YMMV.
