Many years ago, after lots of reading cable research, I decided to believe in the detriment of ’skin effect’, frequencies traveling at minutely different speeds at the inside or outside surfaces of a wire.
Solution: small diameter solid core strands, individually insulated, twisted, within exterior jacket
Myself, the bargain hunter, make it myself type of person considered: tel cable: 4 strands. cat 5 8 strands.
I made a twisted pair of cat 5: 8 strands each leg. Years later my friend discovered a very favorable article about someone making/selling this type. My friend used two twisted pairs of cat 5: 16 strands each leg. We both still use these all these years later. He had high priced cables with elevators, tried others over the years, always goes back to his twisted cat 5’s.
I had 3 setups for comparison (tube mono blocks; tube receiver; SS) purposely used 3 different cables, WBT banana plugs: quickly could switched amp type. The cables all sounded the same to me. btw, no matter which wire, Tubes were always preferred to SS by everyone.
I have tried my friend’s high priced stuff here, I don’t hear differences, just stick with my home made cat 5.
Your 8 ft length is similar to mine. There are considerations against using long runs of Cat 5, perhaps someone can discuss that.
