Adampeter, while all that Al mentions is true, negative feedback has a negative consequence- it increases odd-ordered harmonics in the range that the human ear uses as loudness cues. This is actually more important than frequency response- if you think about it, imagine you and a tiger in the forest- you would be far more interested in how loud the growl of the tiger is rather than getting all the bandwidth of that growl :)
So the enhancement of the loudness cues leads to brightness. Some loudspeaker designers recognize this and design their speakers for amps that have little or no feedback. Usually the amount of feedback is listed in the specs of the amp.
