Most modern systems do mixing in 32 bit float.
What does bit perfect mean?

4. Any differences will be small to the point of irrelevance if the cable has the appropriate spec in terms of capacitance, resistance, etc. Given the details of the source and load impedances vf frequency the changes made by using a given length can then be predicted and measured to validate that calculated prediction. None of this is 'rocket science' or mysterious, just 101 EE.
5. However people will hear differences due to many other factors - e.g. movement of their head, and/or having just heard something before listening now, etc, that in themselves have nothing to do with the cable.

Point me at suitable AES or equivalent papers on the topic I can download which back you up in terms of measured changes shown to be audible. I'll have a look if/when I can.

Jim you had me ‘triggered’ at the mention of Quantum Mech II. I was genuinely dreaming schrodinger’s in my sleep.
And while I can’t remember who did that particular course, I remember not understanding a single one of Bruce Sinclair’s lecture.
Never, never, never again.

Ah makes sense now; you're an engineer. OK well I'm truly sorry for your loss and hope you have a great day.

You are not a sound quality evaluation device
I appreciate that this conversation has moved a bit., but I really don;t understand why you said this. Of course an electromagnetic wave propogates through the field surrounding the conductor, but why or earth does that make it more rather than less plausible that the construction of the cable somehow materially affects the signal than would be the case if the signal in fact propogated exclusively through electrons flowing in the conductor?
All of this is still captured by the L, C and R of the cable and the effect they have on the voltage in which the signal is encoded.

Well, if you believe the QM-wallahs there will be many Universes where he made perfect sense to you.
Just a matter of you finding the Doorway to Summer. (Heinlein reference.)

No need to feel sorrow. I really do enjoy the music. Have done so for decades, incuding the days when I often went to a BBC concert performance at a venue, then heard it played on R3 later. And am able to appreciate the good work engineers do. Without them, we'd have no Hi-Fi at all.

TBF in somc cases cable choice can make a big difference. However the science and engineering behind that are well known.
It is also well established by evidence that people tend to hear 'differences' caused by factors that aren't the ones they assume are the 'cause'. Also established that simply hearing something may affect hearing, altering it *physiologically' so that the same sounds played again may sound 'different'. Have a cup of tea, may alter your perception.
