XLR & RCA, which is better for Esoteric DV-60?


I just got a universal player Esoteric DV-60 to replace my Krell KAV-280cd for 2 ch listening in my system.
To me, DV-60 nails Krell 280cd to the wall.

I am currently using RCA type interconnect from DV-60 to pre.
Just wonder if I change to XLR, better or worse.
Any comments?

Thanks, Tvad.
Any particular XLR you would recommend? Nordost, Cardas, etc? Worth for investment?
I use the mid level priced Audioquest XLR on my DV60 into AR Ref 3 pre and I found it seemed to sound better than RCA, not enough to be a life changer but better.
I want to say Colarado but I may be wrong ($600ish if memory serves)
