Possibly to long.
I have some of the Prime cables as well, quite nice. If you contact them about it there is a lifetime warranty. Though 6 foot is a little long for most basic applications that don't require such length.
Last year I decided to try Blue jeans LC1 much thicker with very large connectors. Seem really good but much higher price compared to P.C. brand.
Glad it was a minor fix as opposed to major overhaul.
Do you notice any sounds quality improvement with the Blue Jeans LC1 cables? For 3 channels worth, LC1 are $99, vs $23 for AmazonBasics.
