    My toroids buzz

    First it was the Creek Evo 100A amplifier. I tried other outlets (with nothing plugged into the device other than AC... no speakers or sources). I tried an iFi gizmo (AC iPurifier and Groundhog +) but it made no difference. I tried an Emotiva line filter (CMX-2) and that made an immediate...

    CXN or Creeky Ruby 2? Streamer/Preamp/DAC for Roon & TV Optical - Please Comment & Suggest

    I would like to hear thoughts or opinions on replacing the Monitor Audio A100 that I have been using as a streamer/preamp/DAC to act as a Roon endpoint and take the TV optical audio signal. The reason for change is the device is not working (I may get it going again, but this is the third one...

    Please explain what I need to make Roon work...

    I am having trouble figuring out what I do not know about Roon… I wish to try Roon because it sounds great and I am tremendously disappointed with the alternatives I have tried for browsing and selecting music. Most of my library has been ripped from my personal CD collection (I rip each CD...
