I am in
total agreement what @
David A has just said.
Prior to me installing the etherREGEN, I was in complete turmoil with RAAT.
- Audio file loading slowly
- Constantly being logged out of both Tidal & Qobuz (I subscribe to both)
- Unable to play a track from Qobuz after having just played a track from Tidal
- Often having to reboot Roon Nucleus+ or reload software
It was a complete mess ...
etherREGEN completely cured all the above. It also brought forth an 'unique' change to SQ. The noise floor dropped quite a bit, allowing you to hear into the mix much more accurately. It made hearing your same old music totally refreshed .. and so different that for once, you're sitting in your listening seat and unconsciously tapping away with the flow of the music yet absorbing every tiny little nuance thats popping out primarily b'coz its all bound together is the most natural cohesive manner .. just like how it happens in LIVE music.
Another area for me that I found is that I always loved tube sound but with my speakers they don't work very well and I also loved what solidstate amps did esp. in the area of LF response. Devialet was a great bridge but one could wished more and what I wished for was better midbass-to-mids and mids-to-treble sonics in the most natural way. etherREGEN brought that in for me most surprisingly and I for one couldn't ask for more! Do note that my etherREGEN still runs on its stock PSU & I am yet to get a Linear one for it.
The router with SFP running from it all the way to the etherREGEN carrying Gigabit internet was another eye-opener .. once again noise floor further dropped and brought forth more ease into the reproduced music. Once again, I am running this router on its stock PSU and have plans to put it on a Linear PSU sometime soon. I am quite confident that it will only get better.
Summing up, with net effect with etherREGEN + Router with SFP has allowed SQ to develop much more natural, easy on the ears and the mind, very relaxed feel to it, a jump in dynamics OR lets put it in another way which would be that you are able to track each and every nuance better and easier yet all this info doesn't jam your brain and is very easy and super enjoyable to follow.
Hope my explanation helps ...
From what I noticed, the latest version of Roon Core (1.8 - Build 846) contains optimizations that impact the RAAT and Devialet AIR protocols.
In my system I can no longer monitor the network traffic, which causes the problem "An audio file is loading slowly". However, I noticed that the degree of CPU usage with the RAAT protocol became lower than with the Devialet AIR protocol. This does not happen in previous versions.
So, it is possible that the latest version of Roon Core has improved the problem "An audio file is loading slowly".

I believe v846 is released for Linux implementations of Roon core only. It will be interesting to see if the Roon optimizations applied to this version will extend to other platforms such as Windows or Mac.
The optimisations applied in this latest version were already operating for servers running on Windows or on the Roon OS (the Nucleus and Nucleus+ servers).
The first paragraph of the release notes states "Today, we are releasing an updated version of Roon for Linux, which will now run on Microsoft’s .NET runtime. This replaces the mono runtime Roon has always used on platforms other than Windows and Roon OS." and a couple of paragraphs later they say "Note: No action is needed for Cores running on Roon OS devices, including Nucleus and ROCK. They already use Microsoft’s .NET runtime."
So whatever they are doing in Build 846 was previously in place for people running their Roon Core on Windows or the Roon OS,. In other words, this release is essentially a "catch up" for cores running on other Linux operating systems. I didn't see any mention of the Mac OS apart from that fact that this release does not apply to the Mac OS.
Feedback in the Roon Community using various Linux systems was very positive. Things are a bit snappier now and using less resources / power is advantageous to user experience and sometimes also audio quality.
I’m a long-time Roon user with my D440 Pro CI amps. I’ve always had some dropouts which I put down to some Internet issues in my house (I have fixed wireless access and it suffers from bouts of latency spikes from time to time). However, after some more testing, I don’t think that’s the issue, I think it’s the Devialet/Roon combo which has drops. I don’t get them with Roon on either a Naim Atom or a Muso-QB.
I have Roon running on a ROCK/NUC, wired into a switch which is linked to my Devialets and the same switch supports a Synology NAS with my local files. All the network kit is Unifi. I get dropouts on both local files and Qobuz (which is what’s making me think it’s something other than the Internet link).
Before posting for help on the Roon site, any suggestions on what I could try to understand more about what is going on?
Thanks
@
wiresandmore - I've got the same setup as you. As you'll likely see earlier in this thread, I had dropout issues when running RoonServer on a Win10 PC, but pretty much only with hi-res (24bit) music. It was all ethernet wired. No wifi. I inserted a cheap 100MBPS switch that eliminated the dropouts. But when I switched to running ROCK on a NUC connected directly to my router, it worked perfectly at gigabit speed. Go figure. My NUC is an 8i7 if that makes any difference. I do have all my local music on a USB drive connected to the NUC. But no stuttering or dropouts on local or Qobuz streamed music. I have had times when a Qobuz song just get's skipped and it goes to the next. I just chalk that up to internet/Qobuz vagaries.
The Devialet Expert Pro has always been a bit dodgy using Roon RAAT to stream hi-res on gigabit ethernet. The update they released in the fall of 2020 did improve things but not completely. Many have no issues, but many still do. Do you have dropouts using Roon AIR as well? I suspect that there are a myriad of possible reasons for dropouts and your local home network is only one. You can try posting in the Roon community but I suspect it'll take another OS/firmware update from Devialet to fully resolve it. Not holding my breath on that.
If it happens often and/or just annoys you, try inserting the 100MBPS switch in front of your Expert Pro. I found no impact on sound quality and the dropouts disappeared.

Thanks! I’ll try that. I have a load of switches but they are all Gigabit, I’ll source a 100MB one. I’ll also see if I can change the speed on the port on the Unifi switch too.
Or get an UpTone EtherRegen which in addition improves audio quality too.

"May or may not improve audio quality" is more accurate. It's also a very expensive way to buy a 100 Mbps switch to test a theory. (And further discussion belongs in Tweaker's Corner!)
