I was referring to the common public "perception" or whatever one might
call it. They're tortured with MP3Pro @ 64kbps as "near CD quality" and
similar uglynesses with WMA etc, and Ogg Vorbis' q 1-3 is definitely
better than that on most tunes I tested. The real dumb users will choose
"near CD quality" in Ogg, get a better sounding and smaller file than
what they're used to and be impressed, hopefully. :) q 3 is default, and
that definitely surpasses what most people are used to.

Apart from that, most people don't have too well-trained ears. I know
some that can't even hear obvious and annoying artifacts unless I point
those out for them and they listen to the same clip over and over again,
having the original clip as a reference. (Note that my hearing is far
from excellent, I can't distinguish anything better than q5 from the
original. In some clips I notice that the stereo picture is somewhat
wrong in Oggs < q4.9, but that rarely happens and I hear it only in my
own tunes that I know well.)

Even Vorbis' -q 8 isn't near CD quality for some people, but they really
are an exception, imo.
