Nut, yes all receivers do put out their rated power; this is governed by FTC regulations, and failure to do so would be a violation of the law.

Certainly one who "wishes to listen" at 115dB would need on the order of 1000 watts for that with speakers of typical sensitivity(such as the Axioms). However that listening level would be tantamount to aural suicide.
