Who's "Jocko" and why is he BANNED? RE: Quote from Jocko who knows what he is on about

"http://www.diyaudio.com/forums/digital-source/29940-how-much-jitter-4.html#post3370964

I would imagine that the jitter of a TOSLINK would be around 1 nSec or so. A really lousy setup. The rise and fall times are slow, and asymetrical. So, I would expect it to sound like crap.

And it does."

Fmak,
What a strange quote from 2004 made by someone who is now "banned" from DIYaudio from the looks of it.

After almost 10 years now since that "Jocko Homo" post, has it been shown ANYWHERE using sound (or even reasonable) methodology that TosLink "sound(s) like crap"?

Even if he is correct about 1ns jitter, has that amount of jitter been shown to sound bad in music? Has 10 or 20ns even been shown to make music sound "crap"? Sure, I can detect 10ns simulated sidebands in a sine wave test tone, but that's not music, is it? (I guess unless someone just listens to sine wave test tones all day and this is somehow important.)

IMO, the answer is NO. A reasonably well designed DAC these days should have no audible jitter issues playing music through TosLink/coaxial/USB. There's nothing concrete to suggest otherwise that this whole "jitter" issue isn't just obsessionally driven FUD further exacerbated by market forces rather than perception and science.
