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.

REGA ISIS VALVE 


Rega does something that to my knowledge is unique among CD-player makers: it builds three matched laser mechanisms for every Isis. One is installed in the player, and the other two are stored at the factory. Should the original mechanism develop a fault, the company will always be able to provide precisely the right replacement. That’s taking customer service to a new level.

I purchased a “used” Esoteric K-05X a few months ago, and absolutely love it.
Alvin, at Vinshine, is a great guy but if you are in North America it is a whole other deal. 
I purchased a ps audio perfect wave dac w/bridge and transport for a little under 2000 and am very satisfied. I only had an old marantz CD player hooked up to an old audio alchemy dde v3 + dtiv2 for comparison. The ps audio gear is quite a bit smother and more analog sounding to my ears. On the other hand I rarely listen to it anymore after purchasing a VPI scoutmaster here, but still glad I have it and will eventually get in to streaming with it some day.
