Of course the reason I mentioned the ASML machine that sells for 300M$ that makes 3nm chips is because it is the most accurate machine mankind has ever made (not including the LHC), The LHC uses super conductive cables so they are in a different class. The ASML machine uses cables that many of us would not accept for our audio playback systems on the grounds that the fancy cables we buy are more accurate than regular cables without 10 kinds of shrink-wrap and cool little wooden emblems on them. If the ASML machine doesn't need fancy cables then why do we? Audio works at very slow and very long wavelengths, cables are easy at our wavelengths. If your stereo costs 300M$ would you demand 80k$/Meter cables you would probably say yes but you would have no reason other than people saying it sounds better. The limit of engineering now is 3nm accuracy and that machine doesn't include 80k$ cables. The ASML machine is literally the definition of accuracy and somehow we demand more accurate signal cables than it does, one of the groups is wrong the audiophiles or the semiconductor industry.
