You would be amazed on how many people have been convinced into buying gold plated optical cables because gold is a better conductor...
Basically what I was doing was using a technique sound engineers use to tune EQs for rooms and venues to help create a flat frequency response. I used a pink noise generator in ableton feeding two tracks and routed it directly into my NXS2 and used an iPad pro with a lightning connection to feed a real time analysis tool. The first track was a dry signal routed to the A side of my NXS2 and I had my B side with the same signal but with a 3 band EQ on it. I would use the NXS2 EQ to alter the dry signal on the A side and then recreate the crossover points and slope in ableton to match the NXS2 and then I could A/B to see and hear any difference. From my measurements I found the Low ISO to be around 290Hz and the High ISO to be around 4.8kHz. The slope appears to be 24db/oct.
I specifically said that in AUDIO testing, non blind tests are worthless. I didnt make any comment about science in general.
Its as worthless as eyewitness testimony, which is wrong as often as it is right for the same reasons. Human construct sensory data with their brains. You are not hearing a true representation of reality. Unless you have a reference that shows that people with golden ears are not subject to confirmation bias or placebo, then Im going to go with the decades of journal articles rather than your opinion.
Not quite sure why youve gone on about Tuberculosis.
Got a reference for your codec story?
