Yes, if the input transformers input winding is just floating, then the common reference point will be totally dependent on a path trough two power supplies (or at least the grounding bypass), power filtering (or its grounding bypass) and various connectors. I can imagine all sorts of junk riding this path, and causing "hell" for the input transformer. Bringing together the ground planes more directly would give the input transformer a fair chance of doing its job the way it was meant to. I'm still gobsmacked. I wonder how many other DACs would benefit in the same way by a direct short grounding path to establish a common ground (!). -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=28307 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
