[sdiy] Vote for your favorite noise source

[Peter Grenader]

You know,  I 've used noise from Moog (whose circuit is huge) and Analog
Systems (whose circuit is about five components) and it basically all works
the same, as far as I can see.

So in my book, noise is noise.

If used for a source of random, I have not seen a difference.  If used for
sound it's usually countored anyway through a filter or whatnot, so it's
'virgin' state I think is secondary.

OK, lemme have it.
