i sorta don't agree with that statement.. i think if you are used to say rupping at 192 with lame, you will get teh same file size aned a MUCH better sound with wma..

now i fyou go 320 with lame.. or use the r3mix setting it will be a lot closer in sound.. but not justifiable for 2 times the space imho.

FWIW i notice less noise with wma.. over eac/lame/r3mix encoding.
