thats right.  and neither do most other people.

i have used lame 3.96.1 or higher at 256kbps-cbr qval=1 j-stereo for
all my stuff, and it sounds great, and gives me around a 7 to 1
compression ratio.

now, if people were honest in their testing methods, they would take a
blind test, that a friend administers.  play song X as a wav, a flac, a
mp3 (with my settings) whatever, but don't tell the listener which is
which.  have THEM say which is which.  (and be sure to on some tests,
not change the format at all)  do it multiple times with multiple
songs.  you'll laugh out loud at how wrong they are.

most people in fact, if they notice anything, notice slight differences
in sound levels, and more often than not, they associate the louder
sound with being the higher quality one.  so if you're really serious
about conducting double blind tests, u need a DB meter to compensate
for any differences in replay gain between formats; in other words, you
want to make sure you have the same sound pressure levels consistent
from format to format for the same song.

i have a 200gig HD just for mp3.  i figured its enough for now, (i have
38gigs free with some more to rip still) and at 256 it would give me the
right mix of quality / size and compatibility, so i could use it in
portables or share with friends easily, whatever.

another consideration is, how perfect do you need your music anyway?  i
have lots of songs and i like them, but there's probably only 100 or so
albums i'd really care enough about to be lossless on.  and then if i
do that, i now have to decide if i'm going to keep the mp3 versions,
for the reasons i mentioned above.

sure, mp3 might be technically "lossy" but that only matters if one can
tell, and i don't think nearly as many people can tell, as some would
lead you to believe.  until they pass a double blind test with
statistically significant results, i don't believe it.

right on.  and i would say flac at 2-1 is not yet attractive, when i
can get 7-1 with mp3, and have an easier time with portables and
sharing.
