Excellent work utgg! Indeed it looks like as you said, a D/C offset which decays over at least 40ms. Here's a zoomed in look at the tracing of the impuse: 18581 Result of those big 1000uF capacitors seen in the 'hardware teardown' (http://mikebeauchamp.com/2014/12/pono-player-teardown/)? +-------------------------------------------------------------------+ |Filename: DC_Offset.png | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=18581| +-------------------------------------------------------------------+ Archimago's Musings: (archimago.blogspot.com) A 'more objective' audiophile blog. ------------------------------------------------------------------------ Archimago's Profile: http://forums.slimdevices.com/member.php?userid=2207 View this thread: http://forums.slimdevices.com/showthread.php?t=104094 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
