Sorry I do not have any experience.
Besides my Sonos and Matrix audio Mini-I pro 3, I have mostly used Raspberry Pi device’s, both USB and Hifiberry hat’s (digital and analog) up to now, so I have not tried the ultrarendu. Mostly these have been for headphone listening.
I bought it expecting to send it back, but it is staying, and once the Chromecast facility is provided I will be 100% happy with it.
