I have done blind A/B testing. WAV or FLAC always beats AAC, at any
bitrate. AAC+ SBR, the flavor used for digital radio, is even more
annoying due to false triggering of the pink noise pumper and the total
lack of any sense of space. A typical 78 RPM analog record has more
ambience.

I do all my entertainment radiolistening via web unless I'm somewhere
without wireless broadband or listening to the AM radio. I find the
vast majority of FM radio stations unlistenable due to the extreme
dynamics processing.


Have a look at some of the comments on the 320K AAC experiment from the
listeners.. Remember them;?....
