Back in the 1980s I owned a small recording studio and I wired my main monitors using 13amp (UK) flexible mains cable (financial reasons). One customer/ producer insisted I use his QED oxygen free copper bla for the session so I wired them both to the power amp and ran the session on his cables. Once the mix was complete I asked my assistant to randomly swap the cables on the amp to test the difference up to my normal safe level (I had a home "disco" light system running that was modified to flash as you approached ear damage!).
Neither of us could tell the difference. Not sure if he continued transporting cables. I have never spent big money on cables since.
