RMS vs Dynamic Power handling? Does the "dynamic" power mean anything?

[canuckle]

Not to be nitpicky, but...

RMS power stands for Rate Mean Square.

Fail. RMS stands for root mean square. As in: the square root of the mean of the squares of the values.

Which is a measure of constant output power over a 1 minute interval.

Fail. It's just an average that in electronics is used to express the power magnitude that can be continuously output by a device... 1 minute, 1 hour, 1 year, 1 decade... there is no time period associated with rms power ratings. It's a sad amp that could only output at its rms rating for 1 minute.

Peak power is a rating of power of a 1 millisecond burst of signal and it is the highest power that the amp can put out without square waving in 1 millisecond

Fail. Again, there is no proscribed period that the power is measured in, it's just a rating of the power that the unit is capable of. If peak power were only achievable for 1 millisecond, it would be a pretty useless rating and the amp would have pretty sad capacitors.
