SQ difference XLR vs RCA ?


I’ve read lots of the discussions on this forum about balanced vs single ended connections.  My understanding so far is that balanced connection has better signal to noise than single ended, which helps if you have hum or noise problems or if you have long runs.  
My question is this:  if I have a quiet system with short runs, do balanced connections sound better?

Anything that I purchase in the future will be fully balanced. I am that convinced. The answer to your question is "I don't think so".

@coralkong , All my analog equipment runs balanced including the tonearm and phono stage. Digital runs are AES/EBU, Optic , Thunderbolt and USB. With the volume all the way up you can only hear noise on Phono with your head in the speaker.  

Balanced is inherently better. Well implemented it had definite benefits. 

Lowers the noise floor, much cleaner signal.
