It's odd that so much attention is being devoted to Roon by SOtM but I guess there's some kind of revenue involved.

 

 

Perhaps it's just so easy that Roon writes the RAAT protocol that SOtM uses for it's Roon Ready and free of bugs as it's tested by Roon.

Main system
TAD D1000mk2, TAD M2500mk2, TAD CE-1, Ansuz Mainz 8 C2, Ansuz Darkz D-TC, 
Qobuz Studio -> Roon ROCK on NUC -> Uptone etherREGEN -> dCS Network Bridge -> AES/EBU -> DAC
HD Plex 200W PSU (4 rail for ISP fiber, router, etherREGEN and NUC)
 
Second system
Qobuz Studio -> Devialet Silver Phantom, Devialet Tree

How are you finding the SQ with 0.4.56?

That depends what you are asking.  I have not noticed any differences between any of the 0.4.5X versions, but I do find that the 0.4.5X versions are a clear step up from any of the previous firmware versions.  So 0.4.56 sounds much the same as 0.4.55, but that's ok, because 0.4.55 was sounding splendid anyway.

Windows 10 PC, Roon, HQPlayer, SOtM sMS-200Ultra, tX-USBultra, Paul Hynes SR4 (x2), Mutec REF10, Mutec MC3+USB, Devialet 1000Pro, KEF Blade.  Plus Pro-Ject Signature 12 TT for playing my 'legacy' vinyl collection.

I just meant in comparison to 4.55.  Thank you for the response.

You do know that I have a fear of Daleks? :S

I agree : I noticed a somewhat better SQ from my SOTM200 going from 4.22 to 4.50. Since that update no more increase in SQ

Check my profile for my audiosystem.

I downloaded the latest version of the firmware (V4.5.6) and installed it onto a new microSD card.

Now when I use MPD or Squeezelite I get glitching and breakup.  I also cannot play DSD (via DoP) without serious glitching.

 

Somehow I don't think the firmware problems are solved.  In the meantime I'm putting the V4.2.2 card back in so I can enjoy the music.

I'm pretty sure the problems with this firmware upgrade have nothing to do with bugs in Squeezelite or Logitech Media Server.

That was not what I meant. Clearly SOtM have some problems in the code running Squeezelite or LMS in their products and Roon supplys the code for Roon RAAT and hence it is tested to work as it should with a Roon endpoint before it is sent out.

Interesting thougt that ROON RAAT does the job for SOtM updates.

 

I dont know what you mean with this as Roon RAAT is the protocol Roon uses between "Core" and "Endpoint" to communicate. SOtM uses Roon code to implement the RAAT protocol to act as a Roon Endpoint and Roon have worked as it should in every update since 4.22 so clearly there are some work being done by Roon to have this protocol working as it should. Perhaps I missunderstand your thoughts :)

Also with roon and dlna

 

Have you tried to change the buffer settings under Roon in Eunhasu?

@Paoz open Eunhasu webpage, open Roon settings page (it is where you activate Roon) . Change buffer settings to higher value it might be 0.1s when you open the page I think I have 0.2s now.

For roon - you need to change the settings. 

Weird - for mpd/dlna its working well for me without the need to change any setting. 

Any chance of a screen shot of your mpd buffer settings ? I'd like to check against mine .

Boot up is slow on 4.56 to my previous 4.21 .. but sound is a really good improvement.

Has anybody noticed: in version 0.4.56 (if not earlier) it is possible to play dsd 64 files that have been compressed by wavpack, at least via MPD and DOP.  I haven't tried dsd 128 files yet. I use a Lyngdorf TDAI 2170, which apparently does not accept native dsd (maybe the other Lyngdorf user afrancois can confirm this) with an SOtM sMS 200 Ultra Neo.  (I do use Room Perfect, as my listening room has various deficiencies, which the system compensates for very nicely.) Wavpack compression seems to more than halve the size of the files I've tried.

 

After successfully updating to version 0.4.40 a while ago, I had various problems starting at 0.4.50 which I mentioned to May, together with the suggestion to look into compressed dsd files.  Fortunatley 0.4.56 works again for me.  I do have the blinking light, though, but will try what happens when I close the eunhasu tab in the notebooks's browser.    

 

I used the following page to play with the MPD settings: https://linux.die.net/man/5/mpd.conf

Initially I had used Squeezelite (coming from Daphile), but I always found the interface rather clumsy.  While at first I had occasional stutter on compressed dsd files, now this seems to have stopped, but I still need to play with the parameters some more.

 

Would somebode else be interested in a button for flipping the polarity (NOT shifting the phase!)  in MPD?  Several record labels are known for consistently inverting the polarity of their recordings (e.g. Chesky), others are hit and miss.  Moreover, wrong polarity seems to be advantageous when using headphones, to prevent unpleasant localization of voices or instruments in your head, as it adds diffusion.  Some amps have hardare buttons to switch the polarity (e.g. the Tact Millenium).  Certain speakers, in particular 3-way systems, seem mask the effect as they  intentionally flip the polarity of one of the frequency ranges.   On "straight" systems, however, the effect is quite obvious.  Consider one stroke of a bass drum.  The membrane of your speaker should first move outward, rather than inward.  Daphile eventually got such an option upon my request, however burried deep in the menus.  I've also asked the Moode developer; he claims that is can be done quite easily by means of alsa in MPD, but has other priorities at the moment.  (The Raspberry Pi with Moode is intended for a differernt room anyway, but for the time being has been hooked up in parallel with the sMS 200.)  I have no experience with Roon, is this option available there?
