It is possible for an amp to have too much slew rate; such an amp may exhibit high sensitivity to RFI or EMI. Low-pass filtering at around, say, 70 to 100 kHz will help, but it will decrease the slew rate spec. Some amps are sold more on specs than performance, though.The minimum slew rate an amp needs is directly proportional to both its maximum output voltage and its maximum signal frequency. For example, if one amp used for full-range or high-frequency audio has a maximum output voltage of 40 volts and another has a maximum output of 80 volts, the slew rate on the less powerful amp can safely be half of what the minimum safe slew rate of the larger one is.
