Interesting that it didn’t sound good with Roon. Some of the reviews out there said that it was excellent as a Roon Endpoint.

I would call it a dac with a renderer.  I've used mine with Audivarna and it sounded great.  I also tried Roon and I was less impressed. 

I ended up buying an Innuos streamer, so I'm using it solely as a dac. 

Sound quality with Audivarna was very good.  Probably true of other similar programs.

As a dac, I'm very happy with the sound quality. 

Well it contains a renderer, operates as an endpoint, and therefore is a network player, but can it be called a streamer if you cannot house your Roon core in it? I believe the term streamer contains both server and player parts. ASAIK this is where we are with the streaming language, someone correct me if I am wrong. 

There are plenty of converters that have built-in renderers, and operate as Roon-ready, such as my Weiss 501, it is still called a DAC with a network renderer, Weiss does not call it a "streamer", but yes you can "stream" with it as it has UPnP- No other streamer or server is required if one doesn’t require Roon.
