I'm looking at a Denafrips Pontus 15 DAC that would be used with an Ultra. Is anyone using a Denafrips Pontus 15 or any or their other DACs successfully with a USB hub. I'd like to take advantage of the Pontus 15's USB-DAC input. So the use of a USB hub would be needed. Thanks in advance for any thoughts on this!
 
Yes, I use this hub to support both media from a usb ssd drive and output to my DAC/amp

Great... thanks! I contacted Denafrips about using a USB hub with the Pontus 15. They replied that there might be stability issues. The results of using a USB hub could be dependent on the DAC used. If it doesn't work out coaxial will be fine.
 
Just wanted to post an update...

After not having success using the USB hub I decided to just try connecting the USB cable direct from the Ultra to the Pontus 15. I played some music from Qobuz and it sounded great.

Then I tried adding the USB hub and the 2TB USB hard drive. Sure enough there was an option in the Audio Output Setting to select USB output / Denafrips USB. Was so happy to see that! In all honesty the issue all along might have been that I hadn't correctly selected the USB Output in the Audio Output setting. Either way it sounds great and I'm very happy to be able to utilize the USB input of the Pontus 15 :).
