600 ohms was used in telephone industry. No need for that today.

There have always been compatibility aspects to matching audio gear. I learned that as a teenager. Sorry your friend didn't.

BTW, Sanders doesn't understand cable interaction either. ;)

Posturing, the point remains: there are commercially available amps with very low input impedance, right or wrong. It's interesting to note that ability to drive 600Ω loads would seem irrelevant today esp for home equipment. And yet the ability to do so is claimed as an advantage or feature by some mfgrs. Even some modern (and vintage) "audiophile" grade opamps specify the ability to drive 600Ω loads at low distortion. So maybe 600Ω capability is somehow relevant in modern consumer equipment . . . Shorthand for "Will drive anything likely to be encountered".

  while some inmates draw diagrams, argue and completely miss the point about using (abundantly found) high Z amps with tube preamps - which eliminates frequency based mismatching issues. :)
