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!!

@pinemountainclub: there are plenty of excellent preamps available on the used marketplace - ranging in price from $150 to $10K + !
Improvement? Depends on how much your willing to spend. The Node works just fine as a preamp. The question of volume control was addressed on the Bluesound Forum a couple of years ago with the previous generation (Node 2):

"We attenuate and do not alter"

Here's a link to that short thread if you care to read it:
