Hi Peiman, High frequencies are very directional, which means the distortion may have something to do with your sitting position. Are you playing back in studio 4 at City? There might be reflections which introduce frequency combinations around your sitting position... Does anything change when you move around?

Or do the speakers simply ignore the frequencies that they cannot reproduce? In other words could these frequencies introduce artifacts in the way that speakers reproduce the sound? I have some sounds at 96k that are very rich in high frequencies, including some strong inaudible frequencies too. When I play these on my system at home (genelecs 8050) I cannot hear anything unusual, listening on headphones sounds fine too. when I play them at university on older models of genelecs and ATCs I can hear some artifacts as if the speakers are distorting at higher frequencies (but no red indicator). interestingly many of these artifacts disappear when I convert the audio to 44.1 as if the distortions are caused by the higher spectral elements (but why not on my system?). What could possibly lead to this kind of problem? Best, Peiman
