So you don't own a good system yet you're sure AC cables have no effect ? Am I hearing you
It's not crazy money to get a system capable of hearing AC cables ... under $10,000. You've had decades ... you have $10,000
what's needed is the intention and effort to listen.
audiophiles don't record music or play music so their "creative" satisfaction is to adjust their system. It's satisfying and I'm all for it ... as a musician you should be too. They pay for music. They love music.
