Note that this list's real expert on audio grounding would claim that
the inclusion of the transformers is a design flaw, and the the real
solution is good ground bonding and the use of twisted pair cables.
Ideally these should have balanced drivers and receiver, but, if I
understand him correctly, even unbalanced they help.
