Switch-on/off click?

[thumb5]

Hello @ada -- thanks for asking, but sorry to say I didn't find a solution and eventually just decided to live with it.  To put it into context, in my system the "click" is much quieter than one often hears when turning a traditional amp on or off - it's just that in the old days my D400 used to be completely silent during on/off transitions.  I have a feeling that this might be a "feature" of the D440 Pro that I simply didn't notice initially.  It's still there, no better or worse, since the CI upgrade.  There's nothing like your "static" noise in my system, though.
