Not to be rude, but people like the stereophile editor have a severe stick up their butt when it comes to reviewing any sort of psychoaccoustic modeling. They have expectations that border on silly, and essentially call anything that falls beneath their pristine ears unworthy. That includes that isn't 192/24 (or likely through their $500/ft cables, either)
As bitrates fall, it quickly becomes obvious that MP3 is actually the worst of the bunch, and more modern compression algorithms (like WMA, MP3Pro, and AAC) do, indeed, outperform it with less bits. Yes, there is truth to the WMA at 64kbps is equal to MP3 at 128kbps, though I'd not use 64kbps, but 96kbps WMA because 128 kbps MP3 has pretty obvious problems with predictive noise.
Its all a bit academic, though. The general populace can't tell the difference between 192kbps MP3 and the CD, and certainly not 320kbps. Certainly not through earbuds, or while jogging, or on an airplane.
