"Should you splash out on those upgraded audio cables to take your music listening pleasure up a notch? Probably not - affordable Amazon Basics RCA cables are more than good enough - confirms audio TechTuber Amir from Audio Science Review."

"Using a constant 4 KHz sine wave transmitted through the cable, a tiny bit of distortion was observed with both cables. There was actually a bit more mains power noise seen with the Kimber cable, but 「practically speaking, the two are identical,」 Amir said... Next, we saw the cables exhibit identical response across a very wide frequency range. There was no phase difference seen in the tests. Same with the square wave rise response graph."

"The Kimber product's only measurable advantage was marginally lower jitter — but Amir noted the Amazon cable was physically longer, and extending the Kimber to match would eliminate even that trivial gap."

"Audio Precision lab measurements show the $4,100 Kimber cable and $7 Amazon cable are functionally identical across all parameters that affect sound quality."

"Black Pearl solid silver conductors drawn in diamond coated dies and insulated with virgin FEP dielectric under the most exacting tolerances"

"competent cables like the Amazon model and better have 「the lowest noise, lowest distortion, and widest bandwidth of anything in your audio system.」"
