Audio nonsense

Any improvement these things may have would be so small they would not even be audible to the human ears..

Everyone has to decide their own threshold for diminishing return. Some believe it is worth spending 1k for speaker wires while some won't spend more than 100. Just like the debate about speakers, amps, etc. Everyone has their own opinion and we need to just accept that.

If you can hear the difference then you need to decide is the difference between $100 cables a d $1000 cables worth the money. Everyone's answer will be different.
