Geckoit might be an artifact of lowpassing the signal?
I see no lowpassing with Lancer on the spectral graph... Am I blind?
Well, I've done some my own tests with this sample coded by Musepack 1.15v --standard and Vorbis Lancer aoTuV beta 4 -q6. It was very hard to ABX Musepack (as it was always for me )... I've decided to hide results and to make 16 tryouts (I beg my pardon for one more tryout with Musepack).foo_abx v1.2 report

And this is Musepack at 193 kbps.
Even if I sense a difference, it is hard and my ears very quick get tired...
