I still see people getting way too hung up on more Watts. There is far more to amplifier design than just the power supply. They tend to read the latest edition of GoldenEar Review and get turning these ideas over in their minds without fully understand the context or the math behind Watts. Worse now, audiophiles believe that an amplifier cannot (under any circumstance) sound listenable UNLESS it doubles its power down to 0.5 Ohms, or whatever flavor-of-the-month DC resistance value they come up with. Not all amplifiers have linear power output into each load impedance, especially regulated designs. I'm not alluding to the non-linear exponential curve across different impedance values, I am writing about a single steady load. Regulated amps double up to the limit of the regulator. Now here is something to think about: How many speakers drop to 1 Ohm? I mean lets be perfectly honest, the Apogee Scintillas, but they have been out of production for a long time, and ever fewer of them still work. How many voice coils in production speakers can handle that current flow? Zilch. By the way RMS is VAC x .707. It's the DC equivalent electromotive magnitude. I don't even need Google to do the math to calculate the net impedance of a driver where, R and phase in degrees or Xc or Xl are known. From that I can also calculate current flow for a given signal magnitude, line drop, on and on... I love trigonometry and three space.
