How Big of a Difference?

Hello all,

I have near completed upgrading my system, but have left my speaker wire the same. My system is as follows- Laptop (Tidal) > Schiit Gumby Multibit > Freya S > Vidar monoblocks > speakers. My usb cable is Supra usb, and I am using xlr connections with amazon basics cables. If I am not mistaken, xlr is already super good at being noise resistance so I shouldn't need to spend more $ on fancy cables at my current level of audio equipment. My speaker wire is traditional 12 gauge wire I spliced from the spool. Nothing fancy. The reason I feel I shouldn't spend money on better speaker wire is because I traded the Supra usb for a super cheap usb and could not hear a difference. On top of that, I used to use single-ended connections using Chord C-line cables, and I could not tell the difference between those and cheap ones. What is everyone else's consensus? Can you guys hear a difference in your system? Thanks for the help.
