Snell E 3

So i just got a an onkyo 805 which is very highly regarded, to drive my HT and stereo. I have snell e3 as the title states, but i am wondering, i can still turn the onkyo up to -0 volume and it still sounds not that loud in my small bedroom. Its rated 130 watts. i had a marantz sr7400 and that seemed louder at -0 rated at 105 watts. However the onkyo seems to push these speakers much more efficiently. Sounds much much cleaner at this level than the marantz. Should i not be worried about this, or are the snells not as efficient as i thought? any insihgt on any of this would be cool to discuss.
