i saw a system with wood blocks all over the gear.. was made from Canadian Spruce he said, the same wood used to make violins or something like that.
i am a magic cable believer- full disclos- and believe i can hear the differences in various cables, in my system, when swapped out with other cables.. the closest thing I've run to lamp cord is Duelund tinned copper ;D
that being said, when I saw the blocks, I kind of went, "hmmm"
they system owner said that they break up the EM and improve performance.. something to that effect.
i do believe that vibrations and EM destroy fine detail, disrupt tube performance and can change the sound output of a system for the worse..and that not all power is the same.. conditioners do change the sound..
but man, i couldn't get behind the whole wood block thing, even after diving into the EM v audiophile rabbit hole.
so I can see how someone could take the things I believe above and roll their eyes just the same as I did w the blocks./ same system also had spruce cable lifters-- edge tech fo sho.
