BTW, everytime I power down I get a sharp "snap" sound from my speakers (not very loud, but noticeable).

Not uncommon at all for power amplifiers. The manufacturer will usually attempt to design an elegant shutdown, but it all costs money. It's a bit easier for the receiver to do a proper silence shutdown since the processor and power amp is in the same chassis and can be sequenced.
Anyway, you've got the right idea, that you have to strip the system down to nothing and start to build it back up until you identify the culprit causing the loop.

My conclusion at this time is that the BFD is quite a nice product for features, but not a HI-FI product.

It's completely fine for a sub though. Don't be fooled into thinking a ground loop has a particular specific 'sound'.
Most people use a BFD with zero hum, buzz etc. You have a ground loop and you'll need to find it if you want your buzz to go away....
