Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: Dennis Fraker

"Perfect" audio involves instantaneous transitions between the high and low levels in the signal. The times taken for the signal to rise from the low level to the high level and back again are called the rise time and the fall time respectively.

If the system is overdamped, then the waveform may never actually reach the theoretical high and low levels, and if the system is underdamped, it will oscillate about the high and low levels before settling down. In these cases, the rise and fall times are measured between specified intermediate levels, such as 5% and 95%, or 10% and 90%. Formulas exist that can determine the approximate bandwidth of a system given the rise and fall times of the waveform.

So, yes, an amplifier that is optimized for damping with fast rise and fall times will subjectively perform audio replication better with one watt than an amp that is not as well optimized. It will not be more "powerful" in terms of average sound pressure level.
