Thanks, I was curious as to how robust the CD transfer was. i have better data on digital transport via AES-3 methods.

Yeah, for as long as this has been tossed around, you'd think someone would have some data IF it were actually a real effect.

BTW, the word you were looking for was "pathetic."

Are you talking about 75 Ohm 1V coax AES or 4V differential AES. There is a lot of confusion among audiophiles about this stuff. Some even have trouble with RCA to BNC SPDIF.

Consistent with expectations, depending of course on frequency.

Whoa, hold on there. IF you can hear??? A large unsupported assertion, no?

We use the same with superconductors, but just move the decimal point. Our unit of measure is MIIT's. Million I squared T.

Ed, I would suspect that the power line itself would have many percents of distortion, maybe even 10% or more. In that context fuse distortion is not something that should keep us awake at night.

In another context, like a fuse in a secondary 24V line to an amp, you might want to look at fuse distortion as causing supply ripple. Would also be of interest to know.

Yeah you may want to get rid off that obvious speculation

I would never insult the functionality of an “automaton”, invoking anthropomorphism intentionally.
Although it is semantics, “work” was for me “job”, “functions designed to execute” not the verb form. Sorry for my English.
I agree with the rest of your post (I had made use of the verb “may” but only in it’s present form )

It will be safer for me if I stick to reading only the posts in a pathetic mode
