I can hear the difference between 1,536 Kbps DTS, 800 Kbps VBR AAC, and 384/640 Kbps AC3 when I watch films, and my equipment isn't very fancy either
I am thinking of retranscoding (again, from flac) to 192 Kbps or 320 Kbps VBR AACbut is it necessary? (this is going to be for playback from my ipod touch)
My FLAC files look something like this...Format/Info : Free Lossless Audio CodecDuration : 5mn 13sBit rate mode : VariableBit rate : 2 726 KbpsChannel(s) : 2 channelsSampling rate : 96.0 KHzBit depth : 24 bits
So, yes, I have the "golden ears" everyone refers too...I can actually hear the difference between FLAC, and MP3 320 kbpsI can hear the difference between 1,536 Kbps DTS, 800 Kbps VBR AAC, and 384/640 Kbps AC3 when I watch films, and my equipment isn't very fancy either

I was able to tell the difference between 320 CBR LAME and 320 CBR Fraunhofer with a 4 hour ABX test
A passed ABX only guarantees that one of them is not transparent from the original source.
Moreover, comparing one lossy format to another (an apple to an orange) is pretty pointless.
But in principle, the artifacts could be disjoint, giving you “twice as many” artifacts to detect -- or even worse (though even less likely in practice), it could “double” an artifact -- say, one note getting a treble boost not noticeable until you compare to the other codec which has a treble cut on the same note; say +D to 0 is inaudible, -d to 0 is inaudible, +D to -d is.
