I think the idea that you have been batting around that the LCD meters are accurate and that the number of watts being drawn is between 0 and 3 is accurate. when you have an A/AB class amp and the AB comes in after say 8 to 10 watts, it it very rare that the AB will be used at all except for brief moments when there is a particularly high draw on the power. In reality most of the time, particularly with efficient or highly efficient speakers the amp is coasting along with 1-3 watts.
