Re: Let's compare numbers and see why mine are different from yours

I'm still trying to fathom what difference it makes if a wire or circuit does not respond at 50 khz when the signal is inherently bandwidth limited to 20 or 25 khz and has practically no energy near those extremes even so. I am also trying to understand what difference it makes if both channels are attenuated by a decibel or 20 decibels at 50khz or 200 khz if they still arrive at both ears at the same relative times as they would if they were not attenuated at all. But above all else, I am trying to find out how a circuit which is slew rate limited at the phono preamp output gain stage to 1V/microsecond would affect the sound of a phonograph record when the most pathological case I can invent for a signal would limit it to 0.1V/microsecond and would usually be far, far, less that that. I don't understand why 1Volt/microsecond is not good enough but 5 Volts/microsecond is fine. Where is the measured data? Where are the calculations? Where is any evidence one way or the other? I do not take anyone's "word for it" without at least some quantitative explanation. And I don't accept unclear analogies or comparisons of circuits where there are many simultaneous variables operative where someone picks out a single one to make a case for a predetermined conclusion. So I ask again, where are my assumed data or calculations wrong?
