Clavil,
Now that is an excellent question! I still have an 11y old Jadis JD3 (one box cdp without tubes) in the second system. This player kept the edge over the likes of Burmester 001, Accuphase DP-78 and DCS P8i when I started auditioning for a new player two years ago because of its beautiful musicality. Eventually - and unquestionably - it had to show the white flag when compared to the AMR CD-77 that I have in the first system since last year.
I have never looked back after the AMR, but all the time I had been auditioning, I much regretted not to be able to hear the new Jadis JD2 Tube or the Jadis JD2 Pro drive + JS2 MkII DAC (sadly > EUR 10k and not within my budget at the time, so I have abstained from asking the distributor). These new machines are technically very much alike the JD1.
Meanwhile, there is the more affordable Jadis Symphonia Evolution Tube (EUR 5,200 over here). Again, I haven't heard this myself (yet), but by all means I can only encourage you to include this on your list of machines you want to hear.
Good luck
