This may sound like a totally wasted question, but nevertheless am going to check
if there actually exist a comparison test of so high bitrate.
I am spesificly interested to see if any codec, (mpc, aac/mp4, ogg)
can produce better. (at any bitrate) I am aware of the "baldness" of the question,
also let it be said that am looking for any test report that can give a conformation
on this, not "word-of-mouth".

I think I'm having a déjà vu.

There is similarity in the topick`s, but i wan`t resoults on lame 320 compared to other lossy codecs, not within the same format.

The answer would probably be the same anyway. It is too difficult to do such a listening test.

If you yourself decide to do such a test, the inclusion of other higher bitrate lossy options, such as Wavpack and DualStream @ 320 would also be most welcome. Up in this area transparency is not so much of an issue except for some rather extreme problem samples, but other issues come into question, such as transcoding, or being to go lossless with a correction file...

Later

Den.
