 Which one of you voted 5 times!!
I haven't (yet).

But, since we do vote 4x/year here rather than 1x/4 years, perhaps I
SHOULD!

 If you are looking for a minimal power drain amplifier, get a Class-D
 amplifier.  They are essentially switch-mode power supplies with the
 input signal as a reference and the output connected to a speaker. 
 Efficiencies run as high as 90%.  These are relatively new and not many
 are available
I don't know if they are many available or not for general home use,
but they are often used in high power car systems, and the fist
comercially available one I saw actually being used was back in 1980
(27 years ago), so they are not all that new.  But yes, they are
extremely efficient.  I always wanted to make one with a digital input
directly controlling the PWM, thus elimination the need for a
conventional D/A converter, but so far have been too lazy to do so.
