Using a tuner to demonstrate differences in cables

 . . . and Amir has done a counter video.

I suspect they are both wide of the mark and are using the wrong measurements / measuring the wrong things.

For instance Amir's video does not even consider GHz noise from routers in the home environment. If there are any possible issues then this may be more insidious and able to find its way way back to a sensitive circuit in one of the connected devices than the relatively weak FM stations he was picking up. I'm not saying there are issues, merely pointing out possible deficiencies in the Amir video.

And that is the danger of people relying on 'measurements' and trusting in the abilities of those doing the measuring . . . . .

'Definitive measurable proof that cables measure  different'.

I think all he did was demonstrate RF rejection.

I have a powered FM/AM indoor aerial. I could have just used some spare basic speaker cable and grown a mullet.

I wonder if can prove that speaker cables sound different by using the skipping rope test?

With the amount of effort that goes to Amit contributions I often wonder if he even has time to listen to... music that is, not pink noise and sine waves.

This is an extreme example but early Nuforce amplifiers would radiate so much interference from the ‘speaker cables that they could defeat a Freeview signal if you didn’t use shielded cables. Shocking design that they fixed in later iterations. I literally needed a new rooftop aerial.
