You have never to produce audiable measured differences and you have never produced a controlled listening test that proved there is a difference.
You produce those then people will accept opinion on the topic.
I've read Toole, Linkwitz and Geddes.
Tell me, I list industry leaders, whose work is widely acclaimed, and you say bad list
. I left out legions of proponents of bi-wiring that don't have the pedigree of these individuals because I knew whatever source I use, it would be shot down "kill the messenger" style. I list only manufactures that are in the monitor business, not hi-fi, mid-fi crap.
So the standard you set for information is they can't be in it for profits. I understand you discounting Bil Low, Cardas and Bruce Brisson*
,..even though Brisson's work is lauded his pricing is truly insane. However your lack of acknowledgement of Dunlavy, Wilson, Vandersteen, Marshiotto, Nudell, and their take on bi-wiring makes little sense to me.*(Here's a guy who most likely knows as much or more about audio cables than most anyone in the world. He puts himself out-there for live scrutiny at shows. His white papers on his site are truly fascinating, and not pseudo-science, he sells DIY stuff that emulates his commercial work, he's recognized by his peers as the man, Monster is still riding on the work he did for them even though he left after just giving them a couple of designs, what gives him a bad name is that he sells $38,000 speaker cables, I say more power to him)
As far as me providing measured audible differences (I have seen a scope trace or some meter readout screen cap or sim, illustrating reduced intermod due to bi-wirng) and producing a controlled listening test so people will accept my opinion, I can't do that. Nor do I want to. What I want to do is convince individuals to try it themselves,...instead of them claiming results are impossible. If one doesn't hear benefits that's fine.
Superposition and the physics of magnetic fields don't just cease because this is an audio speaker cable. They interact and that interaction can produce non-linearities. We can argue circuit analysis til were blue in the face, but when the LF transducer overshoots or rings, does that intermod voltage created just disappear? Can it appear in the HF driver passing through the crossover elements; sure. Can it be better dealt by being damped and absorbed via a lower impedance path directly to the amp terminals, yes.
Can these effects be system dependant; absolutely. Can the distortions be masked effectively with content; yes. Can different source material highlight these distortions, most likely as can some possibly be immune due to spectral weight.
I don't know much about subjective bias other than it exists. In this situation, there is such a strong bias against the possibility of a positive result, wouldn't that mean that such a result would carry more weight than normal? Kinda like the New York Times doing a negative expose on the Democratic party,...or Rush Limbaugh doing a puff piece on Rahm Emanuel.
I've taken part in so called controlled listening tests with others, not on bi-wiring, but on speaker differences (huge). I also suspect and have read that "test taking mode" may produce problems. Right hemisphere/left hemisphere, analytical vs enjoyment stuff, that just circles us back around in endless debate. I'm more akin to relaxation and dropping one's defenses and listening for enjoyment.
That's hard to do when we (you, me and most here) possess technical knowledge about the entire chain; everything from mains voltage from the wall and protection from environmental influences, to microphone and recording techniques, AD/DA design improvements(Sony, 1982; Perfect Sound Forever), different formats and storage media, pre-amplification, IC miniaturization, discreet components and enlargement of equipment, signal manipulation and DSP, power amplification and classes, loudspeaker advancement and trends (the sub/sat "advancement", still firmly rooted is such a two edged sword, room interaction of LF optimization placement is a good thing, however many people went from powerful multiways, to 4" 2 ways w/ a sub) sorry, I digress.
My point is we can be so analytical, and putting the enthusiast knowledge aside and enjoying the recorded event, as you know isn't easy...but very rewarding. Controlled listening tests are prolly the most valid, but it's not kicking back and enjoying the virtues of your new piece.
No, I don't want people to accept my opinion or yours, I want them to listen for themselves.
btw, smack dab in your wheel house,...I stumbled across a collection of those ol' Rodrigues cartoons http://www.angelfire.com/in3/hifijohn/rod.html
