howie,

While the PC will work as your Roon Core, you'll likely benefit from a dedicated server as your Roon Core machine. Look elsewhere from Lumin/Aurender though, as neither can act as a Roon Core.

Nucleus + worth considering for this purpose? All suggestions welcome!

Hi Everyone. The CH Precision Ethernet_HD card is now available for order from our dealers having been certified by ROON. The Ethernet_HD card will be recognized as a ROON endpoint allowing transfer of music files to occur over ethernet to the C1. The connectivity required is:
1. a computing device such as a music server, Nucleus +, etc able to run ROON Server connected to the network via an ethernet cable
2. CH Precision C1 DAC with Ethernet_HD connected to the same network via an ethernet cable
3. an iOS or Android device connected via wireless running ROON remote to act as the user interface for ROON

Up until now, if a C1 owner wanted to run ROON (and I have for years), the only connectivity option was a computing device running ROON Server connected to the C1 via USB and an iOS or Android device running ROON Remote for user interface. One could stream files to the C1 over ethernet using a computing device that was connected to the same network as the C1 and running UPnP software such as Minimserver. One had to use our free CH Precision Control app to control the selection of files to play. QoBuz and Tidal are available through our control app too and are still available using the ETHERNET_HD card with ROON or our control app.

Pricing: for those C1 owners who do not have an ethernet streaming card and wish to add this option, the Ethernet_HD card is $6,000. For those C1 owners who have an ethernet streaming card and wish to upgrade, the cost is dependent upon the age of your card. If the serial number of your ethernet streaming card begins with T17, T18, or T19, the upgrade is $1,000. If the serial number of your card begins with T16 or anything else, the upgrade costs $3,000. ALL C1s EVER BUILT are able to be upgraded to ETHERNET_HD! Real investment protection. Please note that the DIG_IN HD upgrade that we announced last year is a prerequisite for ETHERNET_HD and costs $2,500. This is an essential upgrade in my opinion because we changed the upsampling and digital filters when we released the DIG_IN card and these have made a significant improvement in sound quality of our C1.

If you are a C1 MONO or I1 owner, the same cards and upgrades (DIG_IN and ETHERNET_HD) are available since the cards are the same in all three units. However, availability for these units will be a while longer since ROON certifies each unit individually and we are not permitted to release cards and appropriate firmware until the certification completes.

Installation is easy and will usually be completed by our dealers in less than 45 minutes. The old ethernet card is removed from the back with two torx screws. The new card is installed and the two screws replaced. A firmware upgrade is required and is provided with the ETHERNET_HD upgrade. If you perform this upgrade yourself, please have the C1 unit completely powered off before starting.

Finally, if your C1 is connected to an X1, the X1 firmware must be at v1.5. This was required when we did the DIG_IN upgrade last year.

ENJOY!

Hi Ralph,
Thanks for the updated information regarding the Ethernet HD card.
Sounds exciting!
Clearly this is especially awesome for Roon users. For non-room users, are there further improvements over the previous ethernet card in other ways? I see a mention in another member post earlier in this thread about faster speed or something. Can you clarify?
Many thanks,
Chris

Chris, thanks for the note. When I was at RMAF last week, Raphael Pasche, CH Precision Electronics Designer (extraordinaire !) handed me my ETHERNET_HD card so that I could get familiar with it in my system and update our US Dealers and CH Precision owners. I just got home tonight from the trip and installed the new Ethernet_HD card in my system. No problem. The firmware update takes several minutes so be patient. I am going to have to speak with our design team tomorrow about your question because I hear sonic improvements using ROON. I’ll try ethernet streaming without ROON tomorrow and report back. Here are a few pictures of what to expect with Ethernet_HD and ROON 450F5EB6-50E3-4136-9AF4-A28CCDF06118.jpeg ED436A7D-B7C3-4443-A0FE-77EF0D1DB606.jpeg

One of the prerequisites to install the new Roon-compatible ethernet card is that it must be a C1.1 or to install a HD digital input card onto a C1.

My frds in HK are getting themselves ready now by installing HD digital input cards :

That is correct. DIG_IN HD input card is a prerequisite. This upgrade improves the upsampling and digital filter that we use. We now fit a polynomial curve between data points in the upsampling algorithm instead of padding with zeros. The improvement in sound quality for digital should be quite easy to hear. ALL C1s EVER BUILT are able to install the DIG_IN HD board and v5.0 of firmware. ALL C1s EVER BUILT are then able to be upgraded to Ethernet_HD.

Hi Ralph, once again thanks for your great advice on my ch precision journey so far.

My current setup does not have roon involved as it goes from lan point to melco to ch precision c1 connected via ethernet cables. Would I still benefit from the ethernet_hd card?

Thanks!

Hi Everyone. I've had the chance to speak with our design team about changes to the Ethernet _HD card. Specifically, if you are running ROON in your setup today via USB to your C1 then this update will likely make sense for you. See post #23 above.

But what about those C1 owners who do not have a ROON license and want to continue to stream files via ethernet to their C1 via UPnP ?

There are a few changes that have been made to the ETHERNET_HD card:
1. The voltage needed for card operation has been reduced. Therefore, you no longer have to plug the C1 ethernet cable into a POE switch for power-on
2. The new card can now handle files larger than 2GB
3. The new card can play compressed DXD files
4. The new card can play OGG files
5. we have improved compatibility and made improvements to the way we handle ALAC (m4a) files

My advice is to DEFINITELY get the upgrade if you are a ROON user. Files played through ROON from a local hard drive or from a streaming service with ETHERNET_HD sound better than the same files played through ROON over USB. If you are not a ROON user than it may not be an urgent item on your upgrade list. Have a look at the above changes, contact one of our dealers to have a listen, and then decide.
