Hi All, I’ve changed my Roon eco-system architecture a few days ago: I have moved the Intel I5Nuc8 with ROCK away from the DAC and I’ve bought a SoTM SMS 200 placed in between ROCK and USB DAC (ADI DAC " by RME); library in on USB 3.0 disk attached to NUC, asd before. The problem is that Processi…

Just to be sure: the files are all analysed by Roon already, there is no background work (analysis or backup) going on?

three set-ups: a) files on nas–>ethernet–>nuc-rock–>dac: 8x b) files on ext USB3.0 disk attached to nuc–>dac: 8X c) files on ext USB3.0 disk attached to nuc -->ethernet–>SoTM-dac: 5X same DAC

Yes, all file analysed and no background work. same library as before (give or take some albums, mostly on Tidal)

Very strange. I have no idea, how the processing could be affected if the signal path in Roon between file and the endpoint is the same. The only difference is that it now needs to be packaged in RAAT, but that should not have such an impact on processing speed (I assume). My limited knowledge ends…

[image] Philipp_Schaefer: now needs to be packaged in RAAT Yes, but RAAT is used internally within the Core and Bridge functions of the Server package, if i’m not mistaken.

If you where going from core to DAC via USB then yes you will get faster speed than over network. Networking has overheads that will come into play as also the different os on the device will equally add some differences. Nothing to really worry about. I am interested in if it sounds any better fr…

If it’s direct attached to the core it’s not using RAAT only USB audio.

You are wrong on this account: [image] Connecting Marantz NA6006 to Roon (Airplay mode vs RAAT) Support Hi Chaps, You are both correct these days RAAT is also used by Roon internally it is now part of the application’s architecture. However, in this case the discussion …

So it’s always RAAT. Thanks for digging this up.

Interesting learn something new, but it’s not using the network translation side which will have an overhead and latency compared to converting to usb audio to the DAC.
