I checked the pspoints file, and it is indeed set to the bk-3-spline target. I have no explanation as to why DRC is allowing the HF increase to remain. It is my understanding that the HFs are rolled off to varying degrees in the bk target files. I've been reading posts suggesting the ecm8000 (which I used) can be inaccurate in the HF ranges - could this be contributing to that uncorrected upturn? I also noticed the normal test convolution looked too "severe", so I have attached a new graph of my measured response (red), minimal (green), normal (blue), and insane (purple) test convolutions. Why would the differences be so subtle? Inguz looked at one of my earlier (different) sets of measurements and commented that I was getting an extremely linear response (especially through the mid range) and guessed that I was using a relatively high quality small monitor in a relatively "active" room. +-------------------------------------------------------------------+ |Filename: measured-min-norm-insaneconv.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=3484| +-------------------------------------------------------------------+ -- esbrewer ------------------------------------------------------------------------ esbrewer's Profile: http://forums.slimdevices.com/member.php?userid=12409 View this thread: http://forums.slimdevices.com/showthread.php?t=35615 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
