Some "Good Engineering Practices" can not be ABX tested. [********}
Mr. Krueger, out of curiosity, do you own an ABX comparator box as I suspected earlier?
In-wall NEC CL2/3 rated speaker wire is always twisted pairs, at least that I've come across, so I tried to find if that's a stipulation in NEC Article 640, 400, or 725, but my Google powers faded on me so I gave up. [I provide that link in case anyone else wants to run with it.]Another reason an in-wall wire might be twisted is it then can be encapsulated with another plastic sheath and the circular cross section then becomes easier to fish through holes without getting snagged.
@greynol, I take it you are considering the possibility of recording two segments by tapping the signal at the speaker terminals to then use fb2k ABX, right? [Yes, do that. Don't use a mic.] But my question is how do you time align the two recordings during the playback test? Manually?
Restarting from the beginning still may have a "tell", a giveaway, in that the listener would be subconsciously picking up on the different delays before the music starts.
(The RF field was quite strong, if I hovered the palms of my hands just above the keyboard of my PC it would type random characters..)
Did you wear your tin foil hat?
Twisting cable also decreases its length - the harder you twist it the shorter it gets. So twisting speaker cable increases its resistance per foot slightly, and also makes it a little more expensive to produce.
... Even 'non-twisted' ordinary stranded speaker cables often have each channel twisted around itself. I suppose that the spring effect is what makes them more resistant against a jerk (pun intended).
