Jtinn: While i do not have a PS unit, i was curious as to how much of a load you were pulling and what model PS was being used when you observed a "lack of dynamics" / "current limiting" ?
I can understand such a thing occuring if one was trying to get at or near rated output from one of these devices on a steady state basis. This would be no different from trying to run a power amp near rated power for extended periods of time. Chances are, it would not sound good for long and / or the flaws of the design would become quite apparent pretty quickly.
Personally, i would figure on the PS 300 being good for about 180 - 200 watts of output, the PS 600 being good for about 350 - 400 watts of output, the 1200 being good for about 700 - 800 watts of output, etc... Following these guidelines, one should not run into a problem with any type of current limiting and / or compression, excessive heat, etc... I say that as these figures would allow any of the units to operate at appr 60 - 70% of rated capacity. This results in AT LEAST 30 - 40% dynamic headroom above and beyond what was being drawn on a steady-state basis. Following these guidelines, these units become even MORE expensive as their "usable" power ratings are effectively reduced in order to maintain the "necessary" ( at least in my mind ) amount of dynamic headroom.
