Check headfi, "Watts up" thread.Really? Is there evidence of that? RF is inaudible, so unless you are talking high energy fields modulated with audio frequency signals, I'd be interested in how that is happening. Also in how it is polluting a gound plane, which by definition is low impedance and grounded.
Search on the issue and see what Rob Watts has said about the issue.
It is a known issue, it affects Hugo2 as well.
Yes, Really!
