Advice on buying good CD player that will outperform my Primare cd31


Hello everyone,
I'm currently thinking about changing the cd player and I would appreciate if someone has good advice on buying good red book player that will outperform my Primare cd31.
The budget is around 2000-2500eur and second hand devices are wellcome...
The rest of the system is integrated amp. Bladelius Thor mk3 novitas and Vienna acoustics Beethoven Baby Grand.

Look into a second hand Esoteric player.  It will definitely be a keeper. 
There was a DV60 for sale here for 1900, probably could get it for 16-1700. It was a 6K piece when new
I have had a Primare SP-31 for a couple of years now, and the DAC in this unit is outstanding, better than that of my Esoteric DV60.

Just FYI.
