onkyo 605 vs yamaha v663

[Erman_94]

i've narrowed it down to the two...can someone please point out any noticable differences between the two? (mainly what the onkyo has that the yamaha doesn't)

im asking because i want the 605, but since i live in canada it is very difficult to get a manufacturer warranty on it, whereas i can purchase the yamaha for the same price and get a warranty

so what would i be missing out on if i get the v663?

thanks
