Help settle a streaming argument!

This is a SQ argument and is as follows-  I argue if you connect your streamer to an outboard DAC the streamer does not matter it’s just serving the music to the outboard DAC to do the work.  Therefore, buy a basic streamer.  The other is that you need to buy a top quality streamer and DAC to get great SQ. 
 

I liken it to cd players or the more pretentious cd transport argument- if the intent is to connect to outboard DAC the cd player doesn’t matter the outboard DAC DOES!
 

features and functionality aside!  Thoughts…..
