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 again.
I now have only one set of XLR (Nordost Frey) from pre to power, that's why I want to try from DV-60 to pre.

Will let you all know when the second XLR is avbl.
This will also clear up my doubt on RCA + XLR and XLR+XLR.
I did try XLR cable (Cardas Neutral ref) from DV-60 to pre Simaudio Moon P5.3, then Nordost Frey from pre to power (Moon W-5).
IMO, I feel my RCA (Harmonic Tech Magiclink II) sounds better comparing to the above XLR.

I also heard that XLR polarities on Esoteric differ from those made in USA and Europe. if it's true, not sure this causes lacking of sound stage and liquidity.
