Sorry, late to the game. I generally avoid any thread with the term AudioQuest in it.
You've gotten excellent advice from eveyone who has posted.
I'm most in alignment with Irv.
Unfortunately, I have mostly Monoprice interconnects (which were dirt cheap). They are so stiff, I have had problems with a connection working it's way off the terminal (to the point of hearing distortion and wondering if a tweeter was damaged). I have resolved the issue by pulling apart the right and left wires about 10-12" back so both wires can flex easily to the terminals without "fighting" against each other.
From all I have heard BJC produces high functional-quality cables which would be nice to own without being outrageous in price.
Since you have the background for DIY, it makes sense to price it out and see how much you can save...or you may just want to make your own because you can! You should be able to save money over BJC. It just depends on what your time is worth and whether you would look at it as a task vs, something you would enjoy.
GeneC's option looks pretty interesting, but I am not sure if you can remove the third cable!
