thanks Edorr for the guidance. I rarely use the analog outputs so I'll try disconnecting their power. I was also contemplating a next system upgrade to be a system power conditioner which may bring in additional benefits. And I'll start investigating the PS Audio DLNA server.
DLNA is a surprise to me, I was expecting MP3 like performance and instead got playback that was more musically natural than the JK MkIII asynch USB to SPDIF with none of the tweaking and PC resource stripping used. Harmonic colors are much more correct, I'm not being ambushed by random aggressiveness and vocals never have a "sandpaper" edge. No Jplay or Fidelizer needed and because the PC is running in "normal" mode I can use all the remote options with JRiver MC in theater mode.
