Pros & Cons of Buying an Integrated with Built-in DAC?

Hey Guys,

It has been a pleasure reading this specific post and have learned a lot. Thank you very for sharing.

I also have the Hegel 80 bought used on Audiogon and am loving it. I was intrigued by the addition of an outboard DAC to inscrease the SQ. I had no idea that this is possible or even feasible. Now I know! Thank you all 😄😄. 

I like the H80 SQ and was wondering or more like curious as to which D/A would you suggest under 1k that could potentially surpass the performance of the H80 internal DAC? Would I connect the outboard DAC to H80’s an1/an2 or XLR?
I beleive my H80 is V2 due to an additional line out on the left rear panel which is currently hooked up to a sub.

Thanks guys.😀
There were lots of talk about adding a separate DAC. I thought perhaps I could upgrade this way rather than ditching the Hegel. 
The SQ on Hegel 80 is solid. Just curious as to should I ditch it and update to better one up my one box to multiple, which I am planning on it and keep it the Hegel for my small room.
