So nothing new here then......... the same old links posted, the same old mantra trotted out....
Now one said cables do "magic".... you can't improve on some that doesn't exist..... but "audiophiles" get accused of believing it anyway.
As Lucid has pointed out some cables can "change" the the sound, so don't, some people can't tell the difference between speakers even...
So also this can be measured and controlled by a standard? I think not.
So it's better to be keyboard warrior and quote bits internet hearsay than perhaps gain and little bit of personal experience?
So changing a cable that modifies the sound of the system a little to something more enjoyable for reasonable cost should be avoided?.... Because someone on the internet said it's not possible....
Then it's better to go change say the speakers for hundreds or thousands of pounds to make small adjustment in the sound?
Making a great sounding set-up is often about the attention to detail and extracting the most you can from what you have... carefully matching equipment, which you can't do by reading a few data sheets... you can't tell how a speaker sounds be reading spec sheet for example, or any other item in the audio chain......... but you can by listening to it

..... and on that bombshell... I'll go play some music......on my "audiofool" system
