And yeah, having different formats behave differently is something that would bug me A LOT. :-D As far as gain is concerned, the values are taken from AutoEQ for my Beyerdynamic DT 880 (https://github.com/jaakkopasanen/AutoEq/tree/master/results/oratory1990/harman_over-ear_2018/Beyerdynamic%20DT%20880%20250%20Ohm). So far I've never heard clipping and using EqualizerAPO you've got a setting that automatically lowers volume in case of clipping, it never activated (don't use it for Squeezebox because I wanted to have bitperfect audio, for aestetic reasons more than anything, if I'm being honest). As far as the use of an effects file... OMG!!! I already love it! Gonna study this tonight. ------------------------------------------------------------------------ gorman's Profile: http://forums.slimdevices.com/member.php?userid=56 View this thread: http://forums.slimdevices.com/showthread.php?t=112497 _______________________________________________ Squeezecenter mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/squeezecenter
