How useful is a music streamer if you already own a high-quality DAC and a headphone amp?

The streamer lets you access a hard drive with all your music. I haven't seen a DAC-HPamp that can do that.

If you mean a streamer that has a headphone output...try driving a K70x or something with a streamer then hook up an Asgard to drive the K70x.

Let me rephrase my question:

If you owned a high-quality headphone amp and DAC, used with your computer and with no issues, would you want/or need a music streamer?

In my case, the quest for better SQ leads to separate Roon core and endpoint.
