XLR (Balanced) interconnect cable question

Go ahead and try other cables because, if you don't, you will always wonder - what if?  However, when listening be really honest with yourself - do the other cables truly sound better than your Canare L-4E6S cabling or maybe just slightly different.  You are going to want the new cables to sound better, you are going to want the more expensive cables to sound better, you are going to want the fancy looking cables to sound better....this is typical expectation bias and one reason cable sales continue to be strong - everyone wants the silver bullet that will make their system sound great and if that bullet costs less than a new component or set of speakers then all the better.   If the other cables you try truly sound better to you, then great, there is your answer.  Just do your best to get past your bias when evaluating.  The home audio industry has made a lot of money by convincing audiophiles that a cable (or fuse, or footer, etc.) can be the one thing holding them back from hearing great sound.

Why am I going to want the more expensive cables to sound better?

Expectation Bias, Confirmation Bias, Conformity Bias...take your pick
You can read about it all the time here in these forums....just take a look at the comment by @bewgow just 3 posts ago.  There is an expectation (bias) that the more you spend the better the cables will sound.  People who spend more on cables want them to sound better because they have been conditioned to believe so by reading the opinions of others (conformity bias) and because they don't want to think they wasted their money (confirmation bias).

Yes. Mitch2 is right, there is such a thing a confirmation bias. However, there are things you can verify yourself and that is the sound. If it doesn't sound good then it is not good, just return it. But my point is that if you buy yourself a 12k box and you supply it with $200 cable retail. How much sound you are going to get out of the box. Try a 2k cable and see. If you don't like what you are hearing just send it back and use what you have.

Back in the analog days I definitely could hear a difference with analog cables. Never did with digital cables.

The dealer I bought the Chord cables from thought I made a mistake by going “cheap”. He recommended to test various cables and that’s what I will do. I have the Canare, a set of Belden and now the Chord cables. If I can’t hear a difference I will stick with the Chord. Otherwise time to upgrade… I have 13 channels going so the cables won’t go to waste.
