XLR versus RCA connexion for NAD M12-M22 combo

[hdls]

Hi,

I just bought the NAD M12-M22 combo which works really well in my system (Roon on a computer, playing redbook and high-rez music from a NAS, with Monitor Audio Gold 300 speakers).

However I still have old & crappy RCA cables connecting the M12 to the M22 which a friend told me is some kind of heresy.

I am willing to spend US$ 100-200 to replace them and would appreciate some opinion on whether, in this price range, XLR cables would have a chance to sound better than RCA cables.

I know I should try them both and keep the best one but my usual dealer wouldn't let me take both and bring one back...

Cheers,

Chris
