So unless you plan to listen to music at 120db or something, he's saying that the power on hand in the Pioneer will more then be good up to safe hearing levels
That may very well be so for this particular receiver, and I suppose it depends on what you mean by "good". But in general the fact that an amplifier-speaker combination is sufficient to damage your hearing is not a guarantee that the amp can produce high fidelity sound with the speaker. This stuff about "safe hearing levels" seems irrelevant, to me.
