Yeah, when in doubt, I go by the measurements. If not for REW, there is so much about my setup I wouldn't have known needed work back when I was using a purely by ear approach.
That being said measurements alone can mislead us, like when a 120Hz crossover measured best in REW but sounded terrible.
However, as we found out there is a clear, scientific explanation why. And if one realized exactly what needs to be measured to explain such things (like how quickly the sub rolls off into the noise floor after the crossover frequency), then the measurements and sound quality by ear will match.
So, I believe using measurements as a known reference point plus tweaking to preference afterwards can produce the best overall (subjective and objective) result.
Differences in sound or video quality with cables or wiring (whether we're talking about HDMI, RCA, XLR, speaker cable or wire, etc.) is not something that has any well known scientific explanation or reasoning other than that of expection bias/placebo effect, which as everyone knows is a very real phenomenon that no one is exception to, even the most experienced, golden-eared, audiophile.
So, if the by ear evaluation approach is to be scientific, a double blind test or something along such lines would be necessary at minimum and ideally a measurement of the source before the cable/wire and right after it would be needed to measure transpency mathematically. Sort of like measuring distortion in REW.
(Now I don't claim to be an expert on the scientific side of this matter, but I'm sure there is enough information on this for anyone to see with a simple web search, even right on this forum in the audio theory setup and chat section.)
What I do know is what makes Rythmik subs sound better than the competition, SQ-wise is purely based on science and engineering, as one can see from Brian's informative posts on why he designs subs the way he does and I really like this because I know my LV12R is a great performer not only by listening to it, but by knowing every design choice made in its creation has a technical and meaningful reason behind it. Which is why I bought it in the first place.
Since I'm not receiving any indication of the sort with pricier than average cables/wire, my scientific, analytical mind can't fathom spending any more on cables that is absolutely necessary for acceptable build quality and shielding where applicable.
However, this is just me and I don't expect everyone to share my views on the subject. And I feel the Audioholics.com guys are pretty much on point with the subject, even if their beliefs are in the minority amongst those who have sampled high end audio. (I have not, unless my LV12R counts... which to me it does
