IMHO if you cannot hear a difference with a cable change then maybe it is time to choose a new hobby.
Of course there is no correlation between the $ per ft spent vs sound quality improvement, if any at all.
But there is an audible difference....
If somebody is quite happy to be spending hard earned $ and is happy with the results then so be it, NOBODY here will ever convince them otherwise.
Likewise the flat earthers will never concede that possibly spending more than $0.05 per ft on zip wire will garner any change at all and again that is akin to flogging a dead horse.
Its about time we all just actually LISTENED to some cool music and relaxed a little.....
Headphones on, world tuned out, peace......
