@audiotroy calling BS as I can hear no difference streaming from my Innuos Statement and the Mind2 in my 680D. Crystal freaking clear on matter the streaming source, Using USB, RCA, AES, XLR all sound clear and tone in neutral.
I would use the Mind2 software or Roon and get the Windows Media out of the chain as Mr @lalitk said. Have you done any firm wear updates on your 780 through the Mind2 software?
Sorry peddlers bother me.
