Post Subject: I never seen any PurePowerPosted by xandcg on: 12/5/2021
Hello,
Amir, I have never ever seen a PurePower and I'm far from being a electric engineer, but I'm convinced this "reduce dynamics" thing is at least partially related to the fact the power conditioning device isn't sized to the actual total maximum power consumption of the system, including to cover peaks of the system. In this sense, I would ignore the peak capacity of the power conditioning device and base everything on the "normally" available power.
I think I have posted about it in here before, but since the 1940's or 1950's the advertised power consumption is usually based on the "average use" not the actual total power.[1] This is possible to calculate the total power but I don't remember the math of it but the total maximum power consumption of a 'Class A' amplifier is *several* times more than the output power. IIRC a Class A amplifier at maximum power can reach something between 10...30 times the output power in power consumption.
This is not hard to find about it on the internet, including the math.
[1] there are good reasons for that for products in general but not in advanced audio products.
