To note that the 'cable conundrum' has a certain longevity in discussion is like saying a centipede doesn't have enough legs...
Although my equipment is not SOTA...or even 'sorta sota-ish' is a given on my part, it still strikes me that 'this vs. that' cable is still just creating a very subtle form of eq.
Not saying it's not happening, just on a level that so subtle that only what one hears different is only due to a long-standing familiarity with ones' equipment.
If B vs. Q cables are subjected to measurement, any discernable 'differences' may be buried in the fog of the waterfall.
I'm Not implying that You can't hear it. 3$/ft.>300$/ft., one would hope....
Just don't expect me to, given that I may have just came over for a listen. ;)
