Is it normal i can not hear differences between MP3 and flac?, V5 vs flac? :S Options

I tried LAME V5 vs FLAC source with an ABX test, with at least 3 songs, and i can never notice any little difference! Is that normal?
I tried electronic music too... and it sounds really clear, my hearphones are senheisser hd 518 with a very good quality and my speakers are 2.1 Logitech THX Z2300... (btw i love them)

. . .which would be great, but what David was pointing out (good catch! ) was exactly the fact that, if the test failed, this would not conclusively indicate that mjb2006 had been under the placebo effect before the test; for the previously heard difference may have arisen from a dodgy decoder that would now have been excluded from testing.

Ok, but mjb2006 wrote also that he perceives distortion even using an iPod shuffle as source.

By the way: if his iPod supports lossless, as a preliminary to a more rigorous test, he could simply load it with multiple AAC and ALAC files from troublemaking excerpts of the same track, let the shuffle do its job and test if he can hear any difference between many replays.

So he did! My bad, and thanks.
