You may be onto something there. The arm was rewired with Cardas wire, but unlike every other source in my system, which are dead quiet, there is low level 50 cycles hum (our 50 cycles in Australia is your 60 cycles) with the table. Grounding the earth wire has zero effect. Now I find out that Rega have a system where everything is grounded via the right channel wire.
Seems counterintuitive that an earthing inadequacy would produce sibilance but you're probably right. I might be able to solve two issues with one fix, although not sure how yet.
