QC outputs question

Hi All

Just received my new QC. Quick question - setting up with studio monitors, is it best to go with the XLRs 1 and 2 or the TRS 3 and 4?

I noticed in the manual when it describes them, it says 3 and 4 (TRS) are “pristine”. So I am curious if there is a difference?

Any info is appreciated.

XLR outputs 1/2 are the way to go. I use outputs 3/4 for the DAW etc.
