Expanding a bit on a point I mentioned earlier, the most important factor that determines how much power is required is the dynamic range of the music being listened to. Meaning the difference in volume between the loudest notes and the softest notes. Or perhaps more relevantly for some music, the difference in volume between the loudest notes and the average note.
It seems clear, based on several comments that have been made and on my calculations, that the amp should have no problem playing highly compressed, narrow dynamic range material, such as most rock recordings, at levels approaching 95db at the listening position. I doubt that any of us would want to listen that loud.
However, a symphonic work having wide dynamic range, if well recorded and minimally compressed, and if played with an average volume of say 70 to 75db, can be expected to at least occasionally have brief musical peaks that exceed the 100db maximum spl at the listening position that the amp/speaker combination is capable of.
