Start with that incorrect assumption and your conclusions will be (as they are) incorrect. I've listed the qualifiers so many times over the years that you can easily find them in a forum search, if that's what you want to do.

I assume that you mean with "important qualifiers" something like the known hearing thresholds. So i still find it an interesting question, just because if there is no way to learn to deal with the several bias mechanism than a controlled blind test would be the only possibility.

Well that and someone who actually knows what to test for choosing the cable, the filters coming before the amp, and the amp being directly connected to drivers. Of course if this same theory is used by someone who has no idea how to test a system the theory will work against you and you will end up with a poorly calibrated system.

You found one qualifier. There are several more. But in general, yes, if there's an extraordinary claim, a blind test of some sort is mandatory before making such a claim (if one is to be taken more seriously than my then-6-year-old sister's claim of having a hundred invisible horses).
The control of that test will need to be proportional to the outlandishness of the claim. If someone claims to hear a difference from a 3dB level shift, that's not outlandish. If someone uses a marginally stable amplifier designed by a magician and changing the cable seems to change the sound, sure, that not unreasonable and the bar isn't that high. That's been acknowledged about 200 times in this thread. So what? But asserting a difference because of factors outside of known physics or despite scale differences orders of magnitude below any reasonable threshold... well, I hope you're happy with your invisible horses.

It would be hard to imagine they recommend the chip amps, but some do. In a DIY forum the cost of cabling is arguably a red herring. A pair of small gauge solid silver interconnects can be thrown together with Audionote connectors for the price of a pair of Levis. A Risch Belden design even less. There is essentially no social 'payload' or monetary bragging rights.

@ SY,
if you could tell me a phrase that safeguards against all possible omissions of things we both know about, but still doesn´t take a whole page i´ll be more than happy to use it. ![]() Again, Olive and Toole have shown that even the distinct differences of loudspeakers (afair in the range of several db´s, broadband peaks and dips etc.) will not prevent rating _and_ ranking of these loudspeakers to be strongly influenced by bias mechanisms. Not an invinsible horse i´d think ![]() So, if we are not able to learn to deal with all the possible bias mechanism, why should the passive network approach work? Wishes |

I am not an expert here at all but, I believe that from an engineering point of view there should be an ideal connector between two components with certain characteristics.

One thing is for sure- people can hear frequency response changes on the order of magnitude of 1 dB. So if two cables cause frequency response differences because of, ahhhh, unconventional engineering in the chain, EQing the system to remove that difference is far and away the most likely way to eliminate any audible differences. For sure, it takes the claim of audibility from plausible to imaginary horses. At that point, it's up to the imaginative to do the demonstrating.
