UPnP Sound Quality

[Alve]

Is that Devialet's AIR or Roon/AIR?

I have the same experience air vs upnp, tried both through audirvana on Mac mini. So no air for me.



We did all the tests in Audirvana + AIR / uPNP but as you asked I have just created a Roon trial account and did the same comparison (this one is not a perfect testing as we change the player, I think there is no uPNP support on Roon) but still the sound is superior on Audirvana + uPNP than Roon + AIR. (I played the same song in Tidal via Audirvana and Roon)

For the ones that are interested with a quick test: A Celebration For the Death of Man is the song from Agalloch as there is a guitar intro in the song, you can feel the difference in the sound stage and the bass definition quite easily. Even the guitar sounds more bold and realistic with uPNP.

Of course all the factors should be considered for these kind of comparisons and personal taste is very important criteria but I can definitely say that for me the result is not one sounds different than other. There is a obvious quality difference. If I had the difference that I have between USB and uPNP, I am OK to say it is related with my setup but my current feeling is more like there is something wrong with AIR. (Doesn't matter if it is Roon or Devialet)

Is there any technical document about AIR? Do we know how the async streaming works in the protocol? Is there any jitter solution or any clock fixes between the player and the streamer?
