The end of the Roon ARC audio chain is Android Auto, not the Kenwood hi res car audio amp. Not reproducing bit perfect like USB Audio Pro or Muzecast. When will this issue be resolved. It does reproduce bit perfect music with Dragonfly Black USB DAC when connected, but not my car audio amp. Android Auto will reproduce bit perfect output now, but only with USB Audio Pro or Muzecast for me.
Can we be honest here, are you really going to hear the difference in a car, hardly the best listening room to start with to even resolve cd quality fully. Any benefits of hires if there really are any will be lost to the environment and background noise.
