Looking for a streamer/DAC

Just get a separate streamer and DAC (without volume control) and don’t mess with having to bypass a volume control you don’t need anyway since you have an integrated amp.  Combo DAC/streamers are a gamble as both technologies are evolving rapidly and you may very well want to upgrade one and not the other in the future.  FWIW, and best of luck. 

BRYSTON …. stand-alone streamer/ digital player AND paired with its stand-alone stablemate DAC

- read the reviews .

- audition if you can 

=  you won’t be disappointed,

I'd suggest listening to the BlueSound Node as it's a great entry point.  If you are looking for a higher end unit - I'd explore Moon 280D streamer/DAC...

I prefer a streamer/DAC versus separates due to convenience and space. 

Thanks so much for all the helpful responses. I have looked at the Moon, but will check Bryson and others based on your suggestions. 
and I may just start with the Node to begin my streaming experience and upgrade later. 

Just get one with a volume control to bypass a preamp.

But a good transparent preamp will not affect tubey amp sound
