I have been using Tidal on Bluesound devices. I tried Qobuz and found that I like the sound better on Tidal. Some are no fans of MQA files but I have found about 80% of the MQA version of albums I have listened to sound fantastic. I have moved my entire ITUNES library over the the hard drive on a Bluesound Vault. The only thing I can say that is a negative about Bluesound is that I found it very unstable and would not connect when I ran the Bluesound Node or Vault wireless. Now that they are connected wired by LAN/Cat5 it works perfect. Maybe Bluesound has improved the wireless connectivity aspect of the devices with the i versions. Also of note, IT help with Bluesound is truly top notch. I have called them on three occasions over the years and they are awesome. Adding metadata for album art can be tricky, but I have done it now and it works.
Looking forward to trying the Radio Paradise app on the BluOS. RP is playing MQA files as well.
