comercial Class A

Not all watts hit that hard, i have the impression that tube and class A watt is more efficient than class D. I still remember the day that on a reggae festival (Reggae Geel in Belgium) a 3kW tube system with oldskool wardrobe speakers (Valv-A-Tron hifi from the UK) overpowered a 40kW line array system with class D (powersoft) amplifiers...

Yeah man, power is just a social construct 🙂
