Please be more specific? How did you encode to AAC? Which encoder/software?Thanks.
But today I ABX'ed Rammstein - Sonne and got 20/20. I'm so mad, I need to re-rip everything again And I'm only using Sennheiser HD439, cheap headphones, plugged into my cheap Acer laptop. This is insane. The cymbals are what give it away every time, and there's this "swoosh" sound in general, especially in the chorus.
Note that you may be able to hear artifacts on cheap headphones, due to their deficiencies, that you will not hear with more expensive ones (same for speakers and other hardware).
I don't have the FLACs anymore, yes I'm stupid I know. Anyway, I tried a few other songs, and it wasn't as bad as "Sonne". Guess I'll just wait till iTunes Match will be released in my country then I can upgrade them all to 256 VBR. I know that may be overkill, but at least I won't notice the artifacts as in 128 VBR.
What confuses me though is that if you look at articles and listening tests on the internet in the last 2 years, almost everyone come to the conclusion that 128 AAC VBR is 99% CD quality. That certainly isn't true for me, even with no audiophile equipment....
I would re-rip/transcode the albums with VBR mode 5 of Winamp's AAC (~192 kbps) if you want to go safe, can't really imagine that you could still ABX it (I can't at least).
FLAC to ALAC in DBPoweramp and then to AAC 128 VBR in iTunes 10.7

Someday there will be superior formats, and devices most likely won't play AAC forever.
But Opus is already a superior format which can achieve the same quality at slightly lower bitrates. It's only a small incremental improvement over AAC for stereo music (unless you need low delay), but future work will result in future improvements
There were a lot of effort for a new image lossy format. JPEG reigns the world.
