I just realized that the K2 is a clock synthesizer, that is, programmable clock. Pity because given the same build quality, dedicated clocks will always have lower jitter / phase noise figures.
For me a reason to look away from this gear unless it can follow I2S input as a master clock without doing any PLL or reclocking itself.

A beauty is to pair it w/ Gustard's DDC-U18. Both DDC and DAC connected to Gustard C18 master clock.

Principally I agree but unfortunately the U18 is not really state of the art either:

Don’t know if there is a better DDC or external reclocker that also takes 10 MHz? Usual suspects Denafrips, Singxer and Audio GD don’t have it I think.

Using.an SU-6 and it has no clock input. Audio-gd DI-10 yes. Denafrips yes but not 10Mhz standard input.

But if I use only ethernet with Roon?
yes as roon endpoint, but I can't see the new R26 on the roon ready certified device.... Interesting... https://roonlabs.com/partners
It's not Roon Ready or certified, it's only an endpoint like rpi4 with Ropieee
Can you elaborate on how this is used or the benefits of the feature? Is it just so you don't have to connect via USB/AES etc. and just need ethernet?

Yes, it's a Streamer DAC.
For example using its UPnP function, I could use my Android tablet as player/controller and using Bubbleupnp App n sending audio files from my NAS directly to R26 via ethernet. Cool yes? Same principle applies to Roon and Airplay.
Doing this with my present setup (UPnP).

So, this would eliminate the U18 in the chain?
What would I lose by going to ethernet and limitations?

Could not confirm what bit depth/rate the ethernet supports. Some parts in the publication say "in the future". One part say same as USB and I2S.
SQ wise (on my experience w/ my DAC) better than USB. Since you have less power/jitter interferences w/c USB brings. More or less comparable using DDC but not necessarily superior (w/ my SU-6 experience).
Talking about my experience here w/ my DAC stack having similar features.
Don't know what this feature on the R26 will bring on SQ and convenience. Don't know how well done its network interface is. But it's there.
We need to wait some brave souls who took the plunge and test this part.

Ethernet is just an interface, it does not define audio bitrate (rather, whether it’s 100 or 1000 Mbps). The endpoint like AirPlay or Roon is what determines the maximum bitrate.
Ethernet will exhibit much the same as USB. It too is susceptible to EMI interference and can couple it into the DAC, and it too is buffered by the receiver. So depending on your RF environment and noise of your source it may benefit from galvanic isolation. In my experience less so than with USB but be wary of those big noisy PC PSU’s.
