wattage

I have seen prior threads on this, but none recently that can answer how many watts from an amp are truly necessary.
Take an inefficient speaker, say 86 w/db. at 98 db (which will harm hearing when sustained) 16 watts would be required. Even doubling this to account for transients would be available at 32 watts. Strickly
from an engineering standpoint, are more than 40 watts really necessary? No audiophile terms like bloom, and slam needed.

As I read your post Tennisdoc40, I was thinking about the SPL drop-off with each doubling of distance from the plane of the speaker...
I scrolled down & saw that Almarg had already addressed this point. :-)
I'm thinking exactly along Almarg's lines.....
To make the music flow effortlessly - meaning playback of all the peaks without feeling the music is contained - you will need a lot of watts. 1000X the spec'd wattage at 8 Ohms, just like Almarg wrote.

While I agree that all electronics causes some phase shift of the music signal, I believe that the most flagrant violator of phase distortion is the speaker. Once the listener has corrected this then I would venture to fix the phase shift from the electronics.
