AMP STRAIN : Balanced vs RCA

I’m wanting knowledge … I try to further justify this purchase…

Most established knowledge says that the metal does not make a difference.
Balanced makes a difference in terms of CMRR.

If you have a cheap balanced cable, is that sound different whatever RCA you have?

If you really want it though, it is easier to just get it…as it is difficult to justify with engineering. And many cables do not have engineering specs attached to them.

Raw cable does, but not all, and fewer specs in terms of pre-made cables.

Thanks. What is CMRR?

CMRR is “Common Mode Rejection Ratio’’, which is how balanced get noise on both conductors and remove it equally.

There is no magic, so start with $20 cables and see how they work. (IMO).
