Replacement for RA Opus 21 CDP

Having upgraded by speakers last year I’d like to upgrade from my Resolution Audio OPUS 21 CDP to a better CDP (ideally with a few DAC inputs). I really like the Opus 21 but know there is better out there. I am strongly considering the Cantata but have often read about Wadia, Ayon etc. About $8K would be my upper limit. Geographically I am not in a position to compare these, or other, units myself so having a small list will give me something easier to work through.
Thanks
James
