If RAAT makes a difference, and I believe it does, proving that with measurements may not be all that easy.

If it makes an audible difference it will show up in a controlled listening test, and we can go from belief in a difference to knowledge of a difference.  Then it gets really interesting.  Did you say somewhere you are in an audio club, if so getting their help on the double blind part will make things a lot easier.

Putting myself through blind testing was one of the most interesting things I done in audio, and I encourage everyone to have a try at something like flac vs mp3 using a software tool.  I found it a fascinating process being presented with no other input than my ears, and having to trust them alone.

How about performing a null test to compare Roon AIR with RAAT?
