In Reply to: Power Amplifier: Quality of watts vs. Quantity of watts posted by bssk on June 28, 2012 at 14:41:29:
Some folks with class AB amplifiers (or switching amplifiers will sat sometimes the first watt or even 1/4 watt - where the music signal resides a greater portion of the time - with normal sensitivity loudspeaker. An inefficient loudspeaker - like a magnepan or small monitor forces the signal high enough so the bias point is not in the "small signal" range - of course a higher voltage (and power) amplifier is required. The other way - class A Single ended requires high efficiency loudspeakers to take give you the dynamics from their characteristic low power output.
Note High power and lesser Quality (signal fidelity) are not mutually exclusive properties. And Cost is not a direct relationship either.
