It seems that Output A is PS Audio standard and Output B is JAVS standard as far as the Rose Pin out. Neither are what Gustard uses, but it still might work.

I’m not familiar with the DVI plugs. Strange to see this being implemented. The LRCK pins being reversed may cause an issue. Also I don’t see any DSD support from the hifi Rose so that Pin 15 might be an issue too.
You can try the plug. You are not going to damage anything. You will just have some distortion/clicks/silence if it’s not compatible.

Thanks. Great input. I think my head hurts trying to figure this out. Lol.

I know the feeling.
With I2S not being a standardized output , many companies have gone the route of not making it more compatible so that you have to buy their own DDC.

Ooohh whatcha think so far?

I definitely dig it. Preferring PCM so far but more listening will have to be done.
Fun times!
I will also say that HQPlayer Roon sounds better than Roon's built-in upsampling alone.
It's still early, but I might have to update my signature because I haven't really been using Foobar too much lately.

Which port is being used for FW updates, the normal USB-B or the USB-C? The manual says USB-C but I get nothing on both, installed v5.50 USB driver too but the USBimager doesn't see any devices.

Found it, should be USB-C, had to try a different PC and it worked.

USB-C with the power turned off at the back of the R26, if you still can't get it to recognize the dac try a different usb port or cable or both

The R26 with firmware 1.4 receives its music stream over LAN from a NUC with Audiolinux V3 as the OS. The Roon core also runs on the NUC, as well as HQPlayer embedded. Roon over LAN works great with great sound. Also NAA on the R26 is recognized and works perfectly. I tried installing HQPlayer Desktop there and it also recognizes NAA on the R26.

What I haven't been able to do yet is to connect HQPlayer Desktop on a Windows 11 NUC to the R26 via NAA. HQPlayer Desktop on Windows does not see the R26 with NAA. No device is displayed for selection in the "Device" field. Has anyone had success connecting to R26 NAA and Windows?

Do you think I would see any benefit connecting the hifi rose to the r26 with a i2s cable. On the hifi rose side the i2s is not standard. You can select either RJ45 to HDMI or DVI 24+1 to HDMI. Any benefit over the USB to USB connection I am using now?

I doubt any of these combinations will be better than USB. Personally I would invest in a good USB cable like DH Labs.

Suggesting go to the FMC (Fiber Media Converter) tweak instead.

 

[markkpa]

I'm sure FMC works great. As long as you are aware that connecting the Gustard R26 via Lan is NOT the best sounding solution for this DAC. USB via DDC will always sound better than the LAN connection - I've tested this many times.

A lot of people here myself included will highly disagree with you.
We’ve tested this many times lol
DDC and USB have lost to LAN with FMC many many times over.
In a 200 page thread you are the only one really saying this

@markkpa
I agree, in my system, USB via DDC thru SPDIF gives marginal SQ advantage thru LAN(only) via ROON/UPnP BEFORE the FMC tweak.
With the tweak implaced made a different ballgame. If you have €200 to spare, try it. Add the OCK-1 you have too.

Please bear in mind you have a DDC in between your USB to optimize and w/ LAN still none.

My analogy is simple, w/out any tweaks w/c connection has the best SQ? Go that route...and enhance along the way.

 

[Forgisound]

There are a lot of factors. How good is DDC? Are USB and LAN cables of equal quality? What kind of computer is it and what software is used? And ultimately, how does a particular sound fit into a HiFi system?

My guess is that you have not optimized the USB/DDC setup; i.e. linear power supplies, common grounds, ethernet cables, usb cables, I2S HDMI cable, power cables, external clock, single-ended interconnects, the WIFI connection setup properly to isolate the router from system & more. Get rid of ALL power conditioners except perhaps an isolation transformer to keep Verizon Fios switched power supply from souring the milk on the network/MacBook linear power supplies. I'm way down this road...USB/DDC is the way to go.
