BlueSound Node 2i to Niam NAP 100

Get your gear from Music Direct...30 to 60 day trial and easy return!  That way you know for sure if it will work for you.

I have had good experience with Music Direct.  Also with Crutchfield who offer 60 day return (-5%).

Bluesound staff have posted on their forum that the Powernode 2 series are 120W into 4 ohm. However, I still find it odd that they don't include that in their published specs. 

It is a good sounding unit, but as you point out, it has limited inputs and outputs and limits your upgrade options in the future.
