This may not be the best place to post this, but we appear to have some intelligent people in here, so I'll give it a shot. This gets a little involved, but interesting (at least to me).
OK, so we know more watts is usually better, but not necessarily all the time. From the other post I've got going on amps, we know that more amps is better also. We know how power (watts) is measured, by multiplying the voltage by the current (amps): P = V*A right????
We also know that 'not all watts are created equal', and that more amps is better on a receiver. This leads me to 2 questions:
1. Assuming that we're all living in the U.S., the standard for voltage is something like 120V right? Which means that every receiver is running with a voltage of 120 right? So the only thing that should be the determining factor in power (watts) is current, right??? (We'll leave ohms out of the equation becuase they're a constant in this little experiment) So how can two receivers be rated at the same wattage if they're running the same voltage but different current??? Say I've got a POS Aiwa rated at 200WPC and my H/K rated at 100WPC. If they're running at the same voltage, which I assume they are, how can the H/K with twice the amps be rated at only half the volts (and have 100 times the sound by they way)??? What am I missing here??? Isn't the method for calculating power ratings standardized at this point by the FCC??? Maybe Not??? Is it really in just in how they word their ratings???
2. I've heard that you have to double the power (watts) to get an audible increase in sound - that's from this website. While I don't deny that, I am currently operating under the assumption that that more watts is better (assuming the same 'quality' of watts). For example, if you had two amps, let's say two Adcoms, one rated at 100 WPC and one rated at 150 WPC, the second would produce a better sound right (assuming all other factors constant)? While it may not be louder, I would think that it would just be a little better overall, maybe with imaging and sounstage??? I've not been able to test this theory, just curious about feedback from anyone.
OK, this has gone on long enough, that is all...
