Have been using Roon now for about one month. Successfully integrates my personal library with Qobuz.
I use a Google Nest wifi mesh network with excellent network speed.
I stream to a Chromecast audio device, optical output to McIntosh D100 DAC/preamp, to McIntosh 452, and then finally B&W 803 D3 speakers.
The core is a Windows 10 ethernet connected desktop with SSHD in a separate room. I use a surface pro as the controller (or Android phone at times)
I consistently get bit perfect output (unless the audio source is 192/24 which is down sampled due to Chromecast being limited to 96/24.
Great interface, sound quality, reliability.

I would love to see the ability to change Roon playlist order by batch moving multiple songs. That is the only significant suggestion for improvement I have thus far.
