[QUOTE="Jason Lavoie, post: 49913, member: 159"] Re: Power amplifier sensitivity question.... it might help to think of it in reverse.. if you put a 10V signal into the amp it will obviously clip.. but then if you start backing off the attenuators on the front of the amp there will be a point where it isn't clipping anymore right? (might be one notch above -inf but there will be a point) at this point, it will sound fine, whereas another amp with a lower max input voltage will still sound distorted even if the amp's output isn't running at full power (because the first chip in the signal chain is clipping) As Langston said, it's to compensate for people who might have terrible gain structure.. it's not enough to say you shouldn't be pushing past +4 so the amp clips at +5 regardless of where the controls are set. so why not err on the side of caution and leave more headroom?
