Bare in mind both speakers will need exacting setup to get the best from them, the WP7s in particular.
I've heard the WP7s a fair bit driven by Jeff Rowland 301 along with a couple of other amps when we've swaped them into the system. The owner loves them and in that context they work spectacularly well with some material (material he listens to alot), old school jazz for example however I don't find them particularly coherent over the entire freq range. At worst I hear a disjointed treble that all to often draws the ear toward the tweeter intruding on the music.
I've always enjoyed Avalons though not heard them with Levinson. Some of the smaller models can sound a little bass light at times, lacking a bit of drive, I haven't heard Eidolon so not sure if that carries over into them, Time and Isis certainly sound good to these ears.
I thought Levinson 532 worked well with Focal Maestro Utopia so they or Scala may be worth looking at?
All just my opinion of course and in the context of the systems/rooms I've heard the equipment in. Good luck with your search
