Cable choice is always a contentious subject. I have long believed ( and it is belief as scientific justification seems hard to come by) that cables can change the sound sometimes subjectively positively, sometimes negatively.
Aside from subjective tastes it also appears that a cable that sounds well in one system may not in another. This makes recommendations difficult.
I have also been unable to find any correlation between price and performance.
So, with that preamble out of the way and with over 20 years experience of using XLR/XLR analogue connection the best sounding cable that I personally have found is Sommer Cable, Vintage balanced . This is generally not sold in the retail market but can be bought properly terminated from a custom cable supplier who mainly deal with the pro market. They are Designacable in Nottingham. I assume that you are in the UK but if not buying from elsewhere like the EU before October 31st should be straightforward.
They should cost circa 17gbp/terminated metre. I have replaced thousands of pounds worth of cable from top end well known hifi brands with them to connect my Vivaldi or Vivaldi/EAR 868 to my ATC 50ASL’s and with the single ended version of the cable in other applications.
Another good alternative is Van Damme Starquad ( same supplier).
However, as always with this kind of thing YMMV.
