XLR analog outputs are available as an option which I realize does not make it "balanced"."Could be" what many do these days, on the output of sources and the input of amps, they just add a single ended to balanced output or input opamp converter, which sounds worse than the (single ended) rca which doesn’t use the opamp.

And the only way to find out is to look at the circuit diagram or visually trace the circuit to see if it’s a pseudo balance or a real balanced circuit from input to output, you’ll be surprised how many are pseudo, especially tube amps, pre’s and sources and R2R dacs, even some solid state pre’s and amps though not as many.
