Pretty much all RCA analog cables which meet very easy to achieve electrical parameters called, R, L, and C, (and most do, even dirt cheap ones) sound the same.* There's a giant lucrative market claiming otherwise though which dupes millions of people who don't conduct scientifically controlled listening tests so they are swayed by "the placebo effect".
To learn the secret truth the audio dealers, vendors, and the magazines that accept their advertising dollars don't want you to know, read one of the retired
scientists and long time head of research at the prestigious company McIntosh here
, to get you started. [Although he addresses largely speaker wires.]
In the rare instances where an RCA wire does sound different it is usually simply a minor change in the frequency response, sometimes pleasing to the ear on some music, but not others, due to an irregular R, C, or L, however any deviation from neutral is an error and shoulcd be avoided if you seek accuracy, aka "high fidelity".
