@1971gto455ho - I assume that you believe that every audible difference can be easily measured. I was a cable skeptic for the most part until a few months ago. I got the itch dabble in the voodoo that is all things audiophile and opted to start with a pair of Waudio power cables that I picked up on Amazon for under $50 each. I honestly didn't have high expectations and figured that the 10 awg cables would maximize whatever current capacity was available audible or not. I put one on my Pathos Classic One MkIII and the other on my SACD player. I immediately noticed a significant difference and then realized that I was listening using my DAC so the only change was the power cord on my amplifier. I honestly had mixed feelings about the change because it was far more realistic sounding, but also was more sterile. I considered the change to be objectively better, but part of me did miss the more full sound. As a side note, I immediately didn't like the results with my SACD player and moved the power cord to the DAC where I've never noticed any difference from the power cord even after getting a more expensive Pangea for it. My experience with the power cord on my amplifier convinced me to try a lower end Audioquest interconnect (DAC to amplifier) to replace my Blue Jeans Cable LC-1 and the result was that I kept the realistic sound but gained back the full/smooth sound that I felt had been lost. The improvement was significant enough that I moved up the line (Chicago to Sydney) and again noticed an improvement in clarity with the tone remaining essentially the same. I tried an Audioquest digital cable (Cinnamon) and didn't hear any difference compared to the Blue Jeans Cable that it replaced.
What have you heard (or not heard) that has you so convinced that cables cannot result in an audible difference?
