Setup iMac 2012 Airport Express 2013 - connected to the reciever with tulip plugs Apple TV 2013 - connected via HDMI Sony DN-550 - no network support Everything is wired via UTP Problem: Whenever i stream music to the reciever it sounds a bit dull and not crisp at all. The quality is the same whenever i use the Airport express or Apple TV. I have tried to use different cables and another reciever but the quality does not improve. Tried to find a setting in iTunes to increase the bitrate but i couldnt find it. One person suggested that i should buy a different reciever with built in airplay, but im sceptic about that. Anyone got a suggestion for me to improve the quality?
