The thing is, THX business model is not the same as it was. It used to be a certification tag for home theatre audio, now it just means FIIO paid their licence and use their amplifier circuitry in their products, I don't thing they have a say about what's being done with it. That being said, these measurments don't suggest that there is a problem with the THX Amp, it doesn't make anything worst, the problems are upstream unless I'm missing something.Meh, I'd much rather THX respond and how they granted such label..
