Welcome to the forum.
Paradigm and Axiom share a similar design philosophy and as such have a similar sound. If you like the Paradigms you most likely will like Axiom.
I would recommend the M22 and VP100 or 150 in/on walls to keep to the low profile you wish.
That Denon is a good receiver and many of us here use Denon for or avr's, yu can also look at Onkyo or Yamaha, Harmon Kardon as well. All of these companies have 7.1 capable receivers but it is up to you to buy the extra speakers if you so desire.
There are a few Axiom owners in the vancouver area, I would bet they will be around shortly, but just in case they don't drop in, head over to the Auditions thread in the hearing things forum and see who is listed in Vancouver then send them a PM(private message)
