[QUOTE="The_Quiet_One, post: 8425976, member: 614562"] Slew rate has to do with how quickly an amp can adjust voltage, voltage doesn't change instantaneously. IMHO it's going to have to be a pretty terrible amp to be discernible and then really only easily noticed at the highest frequencies where the slew rate imposes limits on the amps ability to handle the transient response. We are talking about typical voltage swingtimes on the order of a few microseconds (10^-6) with most decent amplifiers. It's worth noting that the effect of an amp's slew rate scales with the amount of power you're talking about. Less powerful amps could feasibly get away with a lower slew rate to maintain a similar transient response of a larger amp with a higher slew rate. A higher damping factor is exactly what it sounds like. It is one of the sources for a loudspeaker's damping which controls it's movement. As far as damping factor you have to look at the entire system, amp and speaker(s). You can easily double your damping factor by doubling the impedance of the speakers you hook up. It's more useful in my opinion to try and look at output impedance of the amp. Bottom Line - Higher numbers can't hurt, but at what point will the gains become negligible to your ears. [/QUOTE]
