@erho You could use an Allo USbridge in which case you connect the USbridge to your network and the Hegel to the USbridge via USB. I use one to connect a Chord Hugo 2 and it works perfectly.
I use dietpi and I have just updated to the latest version with no issues, the update was done using the Terminal program on a Mac and entering the command ssh root@192.168.1.xxx (insert your USbridge ip) then when prompted for a password enter dietpi then at the prompt type dietpi-update and follow the onscreen prompts.
If you want to go the coax route, which might save any possible difficulties with USB drivers / compatibility, you could go for an Allo Digione. Purchase in Europe via their website or the Volumio website.
I got mine from the Allo website if I recall it shipped from France, delivery was quick, regarding the Coax option mentioned above if you have any doubts on usb compatibility I would email Allo and ask.
I haven’t used USB connections before so can only speak from a position of ignorance but, based on all the messages on this forum in which difficulties have arisen, I’m not sure I’d go that route unless there was a specific reason. Since I think that all the inputs on the H190 max at 192Khz and on another thread for the H360 it suggests that DSD drivers may not be available for Linux, Coax seems the easiest option.
@dhusky Hegel H190 do not DSD, only PCM, had a Notebook with Roon connected with Ubuntu installed and there were no problems with USB. USB on Hegel 190 needs no driver as Hegel confirmed.
I also have a Hegel H190 and I’m waiting for the H190 to be Roon Ready, as Hegel say it will be soon enough. I must also add that I am surprised it works so well with Airplay (they apparently have some optimised in-house developed implementation, that might be why it sounds so good).
So that leads to my question: What are your ambitions with a Roon ready network player? Convenience or improvements? I’m fairly confident you will have very little benefit from your first alternative connecting a core directly to the Hegel. Probably you will get similar or worse experience from that. The second alternative might be good, but it’s also adding another thing, doing additional processing, taking up space and costing a small, but not insignificant, amount of money.
If you for example look to play highres formats I completely understand. But I know from my own experience that I sometimes try to make things better with more, often to realise it wasn’t necessary.
I recently updated the dietpi os as described above
It updated successfully
It works with Roon
I have not messed around with it and that is what seems to cause people issues, I have a NUC that runs Rock and functions as an appliance perfectly, with the last Roon update the USbridge was unable to update without moving to the latest dietpi version otherwise I wouldn’t have updated that either.
