Sorry to read of your equipment issues. As you say, it would seem to be a host of bad luck. That said, and not knowing what is or isn't wrong with your Gungnir and Oppo, you might be pleasantly surprised when you receive those items back from the manufacturer. Perhaps the shrill sound you describe is related to the reason you have returned it to Schiit. Even if not related, it could conceivably be "mysteriously" fixed upon its return to you. Sorry I cannot be more help other than to provide good karma. Best of luck.
