Slew rate and rise time

Hi, I just wanna ask if slew rate is the same as rise time. Which of the parameters is used to describe how fast an amp responses to input signal? Is there a minimal slew rate or rise time value which is still compatible with good sonics, or are sonics not depending on these values?

Thx for explanation Herman.

Thank you Sean for your descriptive analogy. I'll keep it also. You know, another issue for discussion is also what the relationship is between gain, volume and amount of power that an amp delivers. Let's say an amp is capable of delivering 200wpc into 8 Ohms. Is this with the volume knob wide open or doesn't it relate to the position of the volume knob? But this is as I say another issue to discuss. I'll start a thread about this.

Sean, I think Herman is right: http://www.amplifier.cd/Tutorial/Slew_Rate/SlewRate.htm.
But I also understand your analogy, Sean. Is slew rate analogous to a car's acceleration speed and rise time to the time a car needs to go from 0 to 90 mph? The slew rate and rise time are a bit related to each other, but if plotted a device with a certain rise time can have another slew rate if compared to another device with the same rise time.
