SQ of ROON running on NAS via Devialet AIR?

[Supra]

The original AIR was very good so I wouldn't be surprised if SQ is on par with Melco. Different, but as good. Roon AIR is also very good! The power stage of the D400 might be its strongest point so you need to think thoroughly on that... does your speakers have a SAM profile?
Maybe a reclocker (DDC) with AES/EBU output in front of the D400 would be a better option? Remember that your D400 will benefit from a good audio-clock in the streamer as it will "lock on to" the embedded clock in the stream (standard for SPDIF/AES) and improve its own clocking.

Thanks, sounds positive on ROON AIR, will give it a try. My speaker is Elac 507 VX-Jet and have SAM profile.

I don't have experience with reclocker/DDC, if I use NAS+ROON AIR, can this be added in between? I want to keep my system simple so don't really want to add another device if I keep the Melco. If not, and ROON AIR is not as good, I may just sell the Melco and look for another one-box upgrade option.
