cable break in

Bob, I think what you're forgetting is that the voltage output of a given amp is a constant just like the voltage in a wall socket. The exact amount of voltage is is a function of the gain multiplier the amp is designed for, which for most amps (regardless of output capacity in watts) is about 25dB +/_ which translates into about 60V +.

Amp output in watts is determined by the strength of the input signal as you turn the volume on the preamp up or down. And the current (which varies with the amount of watts the amp is putting out at different volume levels) is a function of the impedance of the load being driven.

So what I'm trying to say is it's the watts that an amp puts out that changes with the volume. And since the load (usually) and the voltage are constant, the only other variable is the current. That's why little amps run out of gas (clip) when trying to drive current-hungry speakers (like big multiple driver boxes or stats with low impedance) because they can't get the watts/current they need to produce decent sound pressure levels.

So thinking of an amp as a great big "equal sign" with ohms laws on each side in a balanced equation is not how things actually work, plus there's also the additional issue of amplifier inefficiency to take into account.

Nsgarch, a speaker's volume output varies with voltage and the power consumed is a function of the current and the voltage at the speaker for that voltage.
The amplifier takes in a signal of a certain voltage and increases the voltage to a level which the speaker can respond to. Of course the voltage at the output of the amplifier varies and isn't constant (otherwise the speaker would not get louder if the voltage did not increase) and the speaker draws what ever amps it needs at that specific impedence to produce sound at the given level. So a speaker that has 2.83 V/8ohm/90db sensitivity figure will need 28.3 V for a 100db output and 10 watts consumption. The amp will be suppling about 0.35 amps to the speaker and itself pulling 0.12 amps from the wall, still lower than the speakers.
Your figure of 40V is if the amp at full power at what ever wattage it is capable of supplying (or current) into the speakers at the speakers' impedence. If that power is 400 watts then the current is equal to 10 amps. The current drawn from the wall at 400 watts is, of course, slightly higher than 3.33 amps, still lower than the current going to the speakers.

With respect, Bob P.

Break in takes about 2 weeks average playtime. Biggest differences occur around 48hrs. By the way, I've found MIT shotgun or better level have always outperformed other cables...I've owned alot..I mean ALOT!!

>>Break in takes about 2 weeks average playtime<<

NO NO NO. There is no "average" time for cable break in. It depends on the conductor, conductor geometry, and dilectric. It's different for all cables. Same thing with "biggest differences"; some are linear, others are not. Ask any cable designer.
Your opinion is erroneous and misleading. Readers should take it as your opinion as it is not based on any empirical data.

Stanhifi, you can also say that any break in time is entirely an opinion and not based on any emprical data, as you put it.
Dave B's opinion of 2 weeks average time is no more erroneous than your opinion that there is no "average" time, and no more misleading than yours.
Salut, Bob P.
