Actually, modern encoders can give you a headache to discern between
them if you perform an ABX-HR test. With 64kbps it is hard enough, as
the listening tests on Hydrogenaudio has shown us.

Of course, you can always have some artifact that you won't be able to
listen now, but will be aware of in the future, but lame with "-V 5"
already gives people a hard time in ABX tests. I guess that the closer
to "lossless" that you can get is to encode with "--preset insane",
which will give you 320kbps files.

You could encode with a free-format MP3 file with higher bitrates,
though, but the file may not be playable with standard players.

BTW #1, is there any difference between "--preset insane" and "-b 320",
people?

BTW #2, if I am not mistaken, the sound files on most DVDs is encoded
(with AC-3, most frequently), but with a maximum bitrate of 448kbps and
people don't usually complain about the sound of DVDs. (Ah!  Found it here:
