Really depends on a couple of things. You _can_ make a streamer so bad that the DAC’s own jitter reduction system just can’t keep up, and is forced to pass the jitter on.
A half decent streamer with 10 seconds of buffer and a galvanically isolated USB asynchronous connection can be all you need.
One other issue to consider is the noise put back into the line by wall wart adapters, so getting a nice iFi supply is something I recommend.
Personally I like to keep my streamer and DAC separately, so I can choose the DAC and also to ensure the streamer keeps up to date with the latest software services and formats.
