I'm not an expert of any kind, but what leaps out at me is the Wadia has a bad problem that is passing a very destructive signal down the chain. I think the volume must have been turned up a great deal as it was loud enough to blow a speaker (I'm surprised it was a woofer and not a tweeter).
I'm relatively sure what you're hearing is not a ground loop, but a sound I've heard unhappy digital equipment make when something is very wrong in their circuitry. I would throw away the Wadia, or at the very least, have it repaired properly. Sometimes, though, that can happen when something is not connected properly. So, check everything you can. Good luck,
