Wait! Those are both XLR balanced mic cables suitable for high interference and electrical noise locations (like on a stage near theatrical lights and smoke machines). While the can be made to work for analog (but not digital) RCA interconnects, they are far from the best Canare & Mogami choices.
While not addressed @ me, you are taking the point of my post out of context. I simply mentioned what I found to be a good option that after you buy what is needed to make a good DYI cable, your time and materials cost will exceed the cables from Amazon.
They are also easier to work with than Blue Jeans due to the RCA connector that BJC chooses.
I’m again not trying to push this towards a cable debate, but the 3 - 4 cable runs that are typically used in a 2 channel system will doubtfully expose poor performance from these cables.
