what is dynamic headroom?


what is dynamic headroom and do i need to worry about it? i am purchasing a used B&K st-3140 amp and after looking at the specs, it has the lowest dynamic headroom of any B&K amp at 1.0dB. how does this affect sound? same thing with dampening factor? the B&K's is 100. what does this mean?

The dynamic headroom shows the ability of an amp to handle large power output (loud music) that exceeds normal power requirements for short duration of time without distortion. The link below gives good explanation and example:

The dumping factor shows how output signal is proportionally divided between impedances of the speaker and output impedances of the amp - 100 is very good - it means 1% or less of the signal is lost on the output impedance of the amp.
I hope this helps.
