I have just started looking at power amps. I have seen various descriptions that describe one particular amp as being good for PA, another for monitors, another for subs, another for bass, etc. I have always thought that a 1,000 watt power amp was a 1,000 watt power amp, and it could be used for whatever application you wanted to use it for. Can anyone explain why certain amps work better for one application and not for another and if there are certain things I should be looking for in a power amp for use with a bass rig? Thanks very much.
