Why get a separate DAC


I just put together another system in my house. Hegel h120, LRS speakers and BluOS streamer. I had never been exposed to DACs before because my main system is 20 years old. Question is whether a separate DAC is recommended. Obviously the Hegel has a good DAC as does the streamer. What do folks think and why? Thanks

@novatt,

The DAC in your Hegel H120 should sound better than the internal DAC in BluOS streamer. You may prefer the BluOS app interface better / versatile compare to Hegel. If you want to keep things simple, use Spotify Connect with Hegel and call it a day.

My advise would be to enjoy Hegel H120 for now, get your feet wet with streaming. Down the road you can step up to better streamer / DAC separates.
... because of better sound coming from a better dac... or at least the prospect of it!
I use excellent power and interconnect cables on my node 2 and I haven't bothered thinking about trying a separate DAC because it sounds so good.

But my cables are extremely good and cost more than the Node 2,
