You really can't conclude anything from that sinewave. My hypothesis was that the TACT is adding harmonic distortion, but that would be very hard to see on a pure tone in the time domain. If it's there it should make the wave ever so slightly asymmetric. The top trace below is a pure sin, the middle one is that same sin distorted with the function that reproduced something like your square wave, and the bottom has about 5X more distortion (in amplitude) so you can see what it's doing. You'd have to be able to distinguish between the middle and top traces to see this in your pure tone. I wonder whether this is best characterized as harmonic distortion, though - can a digital resampling bug introduce that? As for the noise, I agree with Sean - in most systems is negligible. Mine happens to be particularly sensitive (and I'm to some degree an obsessive audiophile) so I noticed it. +-------------------------------------------------------------------+ |Filename: sin distort.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=6038| +-------------------------------------------------------------------+ -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=53345 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
