Snake oil vs Science

Without opening a whole bottle of snake oil i would value some opinions on analogue interconnects - in particular products with no specs such as the tellerium q ultra black xlr interconnects vs much cheaper interconnects with say Sommer carbokab, Mogami 2534/2549 or Belden 8402.

Im in the audioholics “science” camp for now but value other opinions - does low capacitance etc make a difference on short runs ??? Any preference on above cable options ???

Sorry but this type of discussion has been done to death and really will only descend into chaos.
Thank you for your patience and understanding.
