Use a white or pink noise track. http://en.wikipedia.org/wiki/Pink_noise I would just figure out a good calibration volume at the source. Use the digital volume control of the squeezebox. This way it's easy to write down the calibration levels of various DACs. Example: Set the squeezebox volume to 90. Measure final stage output voltage Switch to squeezebox+DAC. Measure & level to same voltage. Then you would have a calibration level for each DAC compared to the squeezebox internal dac. This wouldn't work as well for comparing other sources like CD players that don't have their own level adjustments. -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=82067 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
