Esben, Fons, on another aspect of samplerates higher than 48k: Is it possible that what is audible from an orchestra for example stems in part from interference or intermodulation of harmonics from above the audible band? Relevant for the reproduction had the performance been recorded to discrete channels? I don't know how to phrase my question better. Gene said Yes to that if there was "something non-linear in the mixing process". I didn't understand that though. Wolfgang
