I recently bought a Schiit Lyr + Bifrost combo and have been having some trouble with an apparent ground loop in the circuit.
I have purchased a ground loop isolator, and this appears to have resolved that issue, however, I am now getting EM interference from the Lyr into the isolator – when I put the isolator on top of the Lyr, it’s almost painfully loud, and when I move it away it rapidly decreases in volume, but I can only get it so far away due to the interconnect lengths on the isolator (~150mm).
It is only an inexpensive car audio isolator (Stinger SGN20), and it has a couple of auxillary earth wires. I have 2 questions:
1. Is earthing the two other wires likely to resolve the interference issue?
Thanks for any help in advance.
