Bluesound icon vs Nad c700

I currently have a McIntosh 352 which I plan to use with either of these setups. I am looking for a streamer for my digital playback that I can use tidal/ roon ect.   The new icon seems to fit what I am looking for but I found a Nad c 700 in my local area for sale for a great price.  It has preouts so I believe I could feed it into my McIntosh and use it in the same way.   At this time I wouldn’t be utilizing its power side but it’s nice to know it has it.   Any reason not to get the nad (especially since I can get it for a lot less ) ? 
 

Powering a set of b&w 703s if it matters
