Unless a problem exists, I would not needlessly complicate a home audio system with xlr.
We run out of things to ’improve’ don’t we.
I tried xlr, and found it a waste of time, but at least I now know.
our home residential systems, the majority of us, we do not have the interference problems that xlr can prevent, nor do we have long cable runs. In fact, I tried 25 lf xlr out from Oppo in video system to preamp in audio system, and had a weird noise, changed to cheap 25 lf rca/rca,worked just fine. Nothing special about that Oppo to my ears, I sold it.
I like that (most, not all) xlr connectors snap/lock in so they will not be inadvertently disturbed. I changed all my RCA to locking rca connectors to prevent that problem.
One of my components, the signal strength of the xlr out was noticably a bit louder than it’s rca out. I didn’t need it, but some, not all, xlr out are slightly higher signal strength. Another, the strength of the xlr and rca outs seemed identical. I didn't measure, just saying, it might be, and if so, it may or may not be beneficial.
xlr may or may not be properly implemented by various OEM, there are standards, so you cannot assume .....
