Gustard R26 R2R DAC with roon
- Thread starter Snoopy
- Start date
Can you share that new testing firmware please? Some users on R26 HeadFi thread posted modification needed to get i2s to work, one pin needs to be modified on cable, if I can recall me correctly.
here you are:

It's your Rpi2.. not the Gustard ? Light system on Rpi2 but i'm curious about R26 ?
I've returned my R26. Sound was not as good as X26pro.
now I have G3 too:
root@RPi2-renderer(ro):/home/migo# cat /proc/asound/timers
G0: system timer : 10000.000us (10000000 ticks)
G3: HR timer : 0.001us (1000000000 ticks)
P0-0-0: PCM playback 0-0-0 : SLAVE
root@RPi2-renderer(ro):/home/migo#
This change something (SQ) ?
I read about the supposed network problems related to the lack of memory on the R26 streamer.
After thinking about it, I'm starting to slide towards an A26 solution for DSD use via HQPlayer.
The problem is, in my opinion, also related to the choice of a streamer with a 100mb input. This may be sufficient if it is well managed.
With a modern debian, it should be possible to use ethtool (and also zRAM).
On my ZenStream with all unnecessary services removed and in NAA mode : 51m used.
25mMbit on ethernet ipv6 (DSD256).. x2 for DSD512.

I've not tested it so far, but I think that not much will change in SQ. Is A26 equipped with more RAM? I'm at 62M used RAM with UPnP, NAA and Tidal Connect services running. Roon bridge memory consumption is R26 problem...This change something (SQ) ?

However, the Roon tests seem to be correct.

I can't find the link to the motherboard chosen by Gustard
Gustard DAC-R26 Discreet R2R Streamer/Renderer
It is true that the streamer is underpowered for the price and only has 128MB of ram, but it still works fine with Roon up to its maximum PCM768/DSD512 without stuttering. (The image is R26’s internal streamer utilization while playing 24/48 MQA.)

Yes tests are correct, but more services need more RAM. My experience with UPnP playback (stock firmware) was stuttering playbackHowever, the Roon tests seem to be correct.

so I started digging into it... Swaping RAM on SD-card is not really good. I've found

I have purchased node 2i, smsl su-10 and gustard R26.
to my ears, the gustard NOS mode with my equipment sounds better than smsl, which sounds better than the 2i using a few dsd files via usb drive for testing.
The only redeeming aspect of the node is directly logging into tidal for masters.
I am frustrated that I cannot use either dac for directly logging into my tidal masters or qobuz accounts.
I refuse to get roped into roon and having to pay them for the rest of my life to play my own music.
might be different if roon was a hidef source and I could stop the tidal and qobuz subscriptions..
passing over stream via bluetooth or node 2i toslink isn’t satisfying either. (Bt 5.0 ldac)
Anyone have a suggestion for an inexpensive streamer that will allow me to login to my subscriptions and just pass the stream to a dac over ethernet?
thanks.

You can use any UPNP app that can login to Tidal to stream music to R26 or other UPnP endpoint. For example Mconnect or BubbleUPnP for Android.
Still 128M RAM it seems.I've found

If you have the money to spend on a overpriced streamer and DAC I'm sure you could afford roon.
The dsp features you get there will improve Soundquality far more than you could ever Archive with different DACs.
A raspberry pi 4 and a 400-500$ DAC would have been just as good if you would utilize DSP features. (Roon does upsampling, equilizer, convolution filters etc).
If tidal and qobuz are both necessary (mqa is a scam and tidal hifi still uses some mqa files) you could have created a tidal subscription in Argentina for less than 1 USD a month.
Best solution (for me at least) is roon with a lifetime subscription and you purchase your favourite music.. qobuz sublime is worth. if you purchase lots of music you have that money back in no time

They should have just popped a raspberry pi4 in there with 2gb ram. And give people to install roopiee XL or another software.

It isn’t I cannot afford roon..
it is getting locked into it. And not being able to use if there is no internet connection to check your license.
i get internet outages fairly frequently. Not going to go there.
looking at maybe setting up a daphile server (has tidal, qobuz and others) though I imagine there may be a little “learning curve”….
Has anyone else ever tried this? I do see many good reviews on it. Only thing “lost” is a little time..
The reason for both tidal and qobuz is to listen to each, compare availability of music I like. Eventually one of them will “go away”.. I know mqa is actually lossy, but so far convenient and masters do sound pretty good. Good enough for “auditioning” what I may want to purchase at least.
