DEVIALET now Roon Ready.

[awkaplan]

Now it´s working, but just after to disable AIR (Devialet Ethernet).
I noticed a difference in SQ between the two (AIR and Roo Ready), a bit more sharp in Roon Air.
Is it possible, or came from my head and i need a doctor?

You're hearing a difference. Those of us who are saying that RAAT sounds better than AIR are hearing a difference. We are in agreement on that point.

When there are differences, there are preferences. Preferences aren't right or wrong, they're simply a result of the fact that different people like different things. When there is a difference in the sound—and you're reporting that you do hear a difference in the sound—some people will prefer one over the other, just as some people prefer tea over coffee and others prefer coffee over tea. The right thing to do is to choose the one you like most. We're listening for pleasure so choose the one which gives you most pleasure. That's the one which is better for you.

Anyone who assumes that we're all going to come to the same conclusion that RAAT is better than AIR or that AIR is better than RAAT is obviously ignoring the overwhelming amount of indisputable evidence available here and elsewhere on the internet and in audio magazines that when people hear audible differences they don't all agree on which is best and that different people do have different preferences.

Everything happening here is normal. A lot of people report hearing a difference but we've had at least one person report they don't hear a difference. Amongst the people hearing a difference a lot of people prefer RAAT and now we have a couple of people preferring AIR. That's the kind of thing that happens every time a new firmware release comes out. It's not surprising that not everyone agrees. The only surprise here is that you're asking whether there's something wrong with you because you don't agree with all of the earlier statements that RAAT is better. There were always going to be people who disagree about the audible benefits of this update and that's nothing to worry about.

You're wasting time worrying. Spend it listening to music via AIR. I prefer RAAT and I see nothing wrong with you preferring AIR. It's no different to me preferring coffee and quite a few of my friends preferring tea.

Well put.  I’m liking AIR for my system, unfortunately still WiFi on both ends, and have had two dropouts in about four hours of listening requiring a reset of the 5ghz radio to restore connection via AIR.  Actually getting a stronger signal (closer to -60dBm).  Will be receiving all parts to build NUC running ROCK today, hoping that getting one side wired will yield improvements.
