XLR or RCA for my new DAC

If the cable length in question is less than about 4-5 feet, a SHIELDED RCA cable is almost as good as an XLR.  Otherwise, XLR starts to win.

Be aware some RCA cables you buy are NOT properly shielded.

Here is one I use that I KNOW is properly shielded:

I do like using RCA: more open. (For short distance). XLR is more ‘direct”,more black/white, miss a little bit “the feeling” of music. Both are detaifull , I’ve tried both, but RCA, brings me more ‘into” the music.
(system: CEC (cd-player), Auralic (streamer),Metronome technologie C6 (dac), Daniël Hertz M6L (préamp) , Wavac MD 805m. (Monoblocks) and the Ilumnia Magister ( speakers)

Cable types could act differently on different setups. It’s really hard to suggest. Buy both of them and stay with one you like the best. 

Just wanted to thank you all for taking the time to reply and share...

@guy-incognito, thanks it's fun writing my impressions of the DAC :)

Unfortunately damn work gets in the way so I'll have to be away from my new toy for the next 9 hrs or so...HOWEVER, I just put in for Monday-through Wednesday of next week for a little r&r time with my new Bifrost. Gonna spend most of that time re-listening to my "new";) cd collection! That's how super crazy excited I am over this thing. 

You know what seriously? I've listened to Iron Maiden "Live After Death" literally countless times over the last 25+ years. I mean over and over and over. Every road trip, every night with the boys going back to when I was a late teen Live After Death always came with or was playing. It's a staple in my cd collection. And I am truly going to ask that this cd go with me in my coffin (I will never go any journey without my Maiden :)). It's classic Maiden so you just pop it in and turn the volume up to full and just jam out!...Last night was the first time I listened to it differently for the first time ever. I didn't blast it, I didn't want to. I heard detail and nuances I truly never have before (and maybe that's because I've always listened to it so loud that about midway through the first track the ears go numb-but it's Maiden that's what you do). At the risk of coming close to using the typical cliché, I won't go there and say it was like listening to it for the first time, but I will certainly say I listened to it and heard it very differently for the first time...That's about the best way I can convey what this DAC has done for me...

Who'd have that you could ever use the term "nuances" in describing an Iron Maiden cd, LOL!
