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

I believe DAC technology will continue to improve for years to come. That stated, having a separate DAC makes the most sense to me.

Just my opinion 
Well you have 2 DACs now. What is you want to improve over the sonics of them? Which do you like most? 
I own a Hegel h160, and have found my Denafrips Pontus II DAC to be superior to the internal one in the amp. It also provides more flexibility (e.g. OS/NOS, more digital input options).

This is not to disparage the HEGEL DAC at all, as it does a good job for an all-in-one integrated.
