Audirvana 2.2 works well UPnP with DLNA and should work well with the Zen Stream. I'm using it right now in my system but don't use the ZS.
I've heard the Zen Stream is tricky setting up as AIO (All In One) is the best way to get started. But I would give a shot to Audirvana 2.2 as that solution will get you hooked up with Qobuz pronto.
I like Qobuz and use it as the quality is consistently superb.
