Charles Hansen said safety ground is a noise antenna.
Indeed he did but my recollection is that he suggested disconnecting or isolating signal ground from safety ground (earth) on the basis that the hazard posed by doing so was typically negligible in modern devices. Correct me if I'm wrong but I don't recall him ever suggesting that safety earth be disconnected from e.g. metal casework.
I agree with the basic idea - no signal ground in my audio system is connected to safety earth. The only way metal cases can rise to mains voltage is if isolating transformers fail by shorting secondary to primary. That's a very remote possibility but, should they do so, I'd expect the ECLBs to trip.
IMHO Blackdog is correct.
