The Touch's digital volume control will not be a quality issue at the moderate levels of attenuation I was suggestion. However I have an even better solution. Change the output volume of the noise test file. Use something like Audacity (http://audacity.sourceforge.net/) to make the test noise file to a volume db level that more approximately matches your music selection. I made a bunch of test noise files and put them on my server here: 15 seconds of pink noise at various levels. http://ben.nerp.net/noise/ -- 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
