There is no reason to use a trigger, the auto sensing feature works perfectly unless of course you have the volume at inaudible levels. I've got 3 of these and have been using that instead of having to deal with triggers and their setup. I highly recommend. Still amazed at how cool they run - and I have mine in a cabinet. Oppo 103 gets warmer then the amps. Let me know if you have any other questions.
There is no perfect display, quit looking for faults and enjoy
