Will a Chord Hugo 2 make a music streamer addition obsolete?

I agree, buy a good dedicated streamer.     

If you add a 2Go to your Hugo 2, it will add a functional streamer that serves as a roon end-point, accepts external storage, etc...  That said, you can add any streamer to the Hugo 2 but the 2Go is an elegant and portable solution.  

Full disclosure, I am a Chord dealer.  

Ok, thanks all.

I was hoping your answers would read that the DAC is so good, a streamer wouldn’t make a noticeable difference. 

I have the Hugo2 and run it off Qobuz on my phone into Noble Viking Ragnars and it sounds so good I sometimes can't even take it, it makes the music so emotional.  

On my home system, I run Audirvana with no streamer and have insane sounding audio.  I'm not sure what a streamer brings?

The Chord Hugo 2 is a DAC/Preamp/Headphone amp. By itself it has no ability to receive a streaming signal.  While, as others have noted, you can use a PC to send a streaming signal to the DAC, this does not give a good quality signal. PCs tend to be very noisy because of all the other computing functions under way. That's why everyone is recommending a stand-alone streamer to pair with your Hugo.
