First off, if you can’t hear differences in cables you have either a hearing problem or a resolution issue.  Also, Fun fact...dug out some old cables I have on hand just to check my ears.  They all sound different...sorry Audioholics 😔  Reminded me why I love MIT products...just so much more realistic sounding on every level!  My REV MIT loom delivers better tone, articulation, clarity, dynamics, bass definition and extended airy highs.  Everything sounds muffled and constricted comparatively!
