Blind testing is also helpful. I have done a setup with 4 feeds going into a digital mixing console: raw audio, 128kb/s MP3, 128kb/s AAC and Auto ALC, the feeds were phase synced and I got my friend to move the faders, to switch feeds, the AAC and MP3 were easy to pick, but the difference between the ALC and the raw was harder, but still there.
