Either optical or coax will enable the audio to be passed to the Atoll and quality will be dictated by the DAC in the Atoll. Music will be much better from a stereo integrated rather than the AV amp. I'm not a Sony owner but have had my Pioneer blu ray player connected by both HDMI and analogue at one point.For 5.1 I will go through the AV receiver as usual, but I am looking for an option to play standard cd, stream and USB music through the Atoll integrated amp without using using the receiver.
You could eventually, if desired, get a standalone CD player which in my experience will give a better performance than a blu ray player. I not longer use my blu ray player for stereo music as I have two standalone stereo SACD players.
