David, you really appear to be caught up a bit too much in the power thing. The M80s are slightly above average in sensitivity(91dB for 1 watt)and any of the units in the 100 watt or more area should have more power than would be needed. For example, the difference berween 120 watts and 140 watts is only 0.67dB in maximum sound level, which would mean that an M80 playing a peak at 112dB with 120 watts could play it at 112.67dB with 140 watts. The difference would be insignificant and you'd be highly unlikely to have a peak that high in the first place. A more commonplace occurrence would be playing at a comfortably loud average level of 81dB, which the M80s would need about a tenth of a watt to do.
The fact that you have the money available doesn't mean that it has to all be spent on this item. $500-$1,000 can buy you a whole bunch of CDs and DVDs to enjoy.
