How important is a preamp for purely digital sources?


I’m currently deciding if I need a pre-amp in my setup.
I’ll be using a Bluesound Node 2i as the source and a McIntosh MC7100 as the power amp.

the question is ... how much sound improvement will I get by adding a pre-amp knowing that all my source material will be digital? Will it be more beneficial if I add a quality external DAC instead?

Thanks!!

I find a system sounds better with a
Preamp if you are going digital 
look into R2R Ladder Dac
