Bluesound Powernode 2i as Music Streamer

I have a Bluesound Powernode 2i  as a music streamer and amp.  I want to upgrade by adding an amp. Can I then use the Bluesound Powernode as a music streamer?  It has only speaker output.  Will I need a Line output converter?  Where would I get one?  On my better system I have the Bluesound Node 2i and Parasound Halo 21+, which works fine.  Thanks.
Looking at the power node you have a 3.5mm headphone out. You should be able to get a 3.5mm to RCA cable. 
WOW!  Thanks, I did not think of that.
Will I get a quality signal from the headphone output to the amplifier line in?
I tried the headphone out, as you suggested.  It sounds fine.  Thanks!
Awesome! Glad to hear it all worked out for you.
