Speaker match for Powernode 2

I’m looking for suggestions for bookshelf speakers in the US$500 range that match up well with the Bluesound Powernode 2. I am currently using a pair of Elac B5s in a second system in my basement. The Elac UB5 would seem to be a natural upgrade, but I am concerned about the ability of the Powernode 2 to drive them adequately.

Is anyone using a Powernode 2 to drive the Elac UB5? Any other suggestions in the $500 range? The Monitor Audio Bronze 2 looks interesting because of its high efficiency. Bluesound likes to promote their sister company PSB, so the PSB Imagine XB could be another option.


That thing looks sweet! It's small enough to bring with you when you demo speakers.
