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

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.

Chadnliz, Tvad
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 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)

Thanks, Tvad.
Any particular XLR you would recommend? Nordost, Cardas, etc? Worth for investment?
