UPnP mode compatibility

I’m currently feeding a Sonore utraRendu (with Signature power supply) from Audirvana+ (with much delights). I’m considering upgrading to a DCS Network Bridge. The DCS website states that the NB supports UPnP in asynchronous mode. →

  • Is it the mode used by Audirvana+?

  • Has anyone already tested this gear with Audirvana+?

  • Are any compatibility problems to be expected?

Thanks very much in advance.
