Adrian, although a slightly better deal on the X4000 might be available in the U.S., that looks like a very good Canadian price. The key factor differentiating receivers these days is the Room EQ provision, and as CW comments, the X4000 has the top XT32 version of Audyssey MultEQ. I'd have a similar view of a similarly equipped Onkyo model if you could still find for example the 818 or 929 at a good price.
