Any time I've ever tried to "listen" to cables, I've been able to convince myself that I heard differences, as long as I was looking at the cables when I changed them and listened to them. Which is to say, that expectation bias is, like, a thing.
In blind ABX testing, I could never do better than random guessing. Any kind of cable. And let's not get started on digital cables. USB cable either works or it doesn't. In general, I just don't believe that cables which meet specifications for any given application could possibly sound different from one another. I understand that there are passionate, smart people who swear they can hear a difference- but Occam's razor would suggest that "expectation bias" is the best explanation.
This is not to say that one should skimp on cables completely. Good solid connectors are less likely to fail, etc.
But Canare vs. Mogami? Buy the one you think looks the coolest.
In the end, that's the one that will sound best to you.
