the analogy I always draw is to wine.
the difference between a $5 bottle and a $20 is perceptible. but, the higher you go, the returns diminish exponentially unless you have a specific taste... and at some point paying the excessive amount of money becomes status not necessity.
yes, potatoes are conductive, but they don't have any shielding and the distance the signal travels in those experiments is irrelevant to practical applications. it is essentially a big wire nut.
if your application is long distances through conduit or many cables run in parallel you need higher quality ones with shielding. Granted, that is not the typical listener's case.
With wine, the price literally affects how we perceive the taste of the wine. https://www.gsb.stanford.edu/insights/baba-shiv-how-wines-price-tag-affect-its-taste
Although this research came out before the fMRI debacle...
What fMRI debacle?
I remembered hearing about it. Turns out there was this published in 2016 which I'm pretty sure was the issue I heard about. https://www.vice.com/en/article/fmri-scanner-study-flawed-pnas-anders-eklund/
As to whether anything more came of this I'm not sure.
Wow I hadn't heard of this, but at least the article shows that they were fixing some of this stuff back in 2015. Hopefully by now those bugs have been ironed out. Very interesting, thank you
