Single ended vs xlr balanced

I have switched backwards and forwards (going slightly mad in the process) testing (long run) interconnects.
I know some sound engineers, and they tell me I am probably persuading myself that balanced is better than single ended and THERE IS NO REASON WHY SINGLE ENDED CAN SOUND INFERIOR TO BALANCED. Sorry to use capitals but this seem to be a fair summary of the be all and end all of technical discussion. If I was to guess however, my mind would tend to follow the technical opinion not go against it, surely? In my mind the balanced is a deeper more airy sound, just better presence all round. The technical response is that I am not comparing like with like, as the balanced runs at higher voltages and subsequently higher volume (6db). I had a shock at this news and found out therefore by accident that my Bryston 28bsst2s amps have a switch upping the output from 23 to 29db to compensate. Also did I hear properly that Bryston kit is set up preferring balanced? My processor is a Bryston sp3 so maybe my preferred balanced system  is what I needed anyway. But it is odd that a reputable company like Bryston would have such a policy (if it has foundation) and not stress that on their literature. If my system can be adjusted for speaker levels then volume output is irrelevant - or is it if that higher voltage has some effect?
And don't get me started on aes/ebu vs spdif! The aes to me is noticeably superior for the same reasons as the rca vs xlr debate. Then hdmi vs spdif ... (Time for my medicine ........)
So my question is - forgetting technicalities which can get more and more complicated by the minute  - do other peoples' ears agree with mine?

The only absolute in this hobby is that there are no absolutes.

I’ve been down the balanced road and down the single ended road.
Just as with everything else in life, they all have their positives and negatives.

The biggest advantage of balanced cables is that they lock in place.

The biggest advantage over ... what? ? You can buy locking RCA connectors, if that's what you want.

I've been using balanced and unbalanced where appropriate for many years, both in my work as a musician and live sound mixer, and as a home audio freakazoid. Balanced live means no loss on long cables, and dead quiet, humless (usually) sound. If hum raises its ugly head you can kill it with appropriate ground lifting. Just make sure you don't kill the musicians. In home use I use XLRs because I CAN here and there (DAC  to preamp, preamp to amp, although my power amp is likely not balanced and a good RCA sounds identical to the balanced cable on that amp…still…the click of an XLR is somehow comforting). Short runs of RCAs work fine and the better the cables the better they seem to sound.
