[QUOTE="John Roberts, post: 49935, member: 126"] Re: Power amplifier sensitivity question.... You can generally ignore input stage clipping in power amps as a potential problem since competent amp designs accommodate typical line level signals. Back in the day, there were amps with the attenuator in the very front end before any active electronics, that could literally accept speaker level signals as an input source and pad them down to use without any distortion, but that topology was unbalanced so dropped in favor of modern low cost active electronic balanced inputs. I'm not sure we need even more ways to specify power amplifiers while they literally are voltage amplifiers so specifying output voltage is not that crazy... probably less crazy than input sensitivity, while changing that now would just irritate all the people who worked to figure out how to use the existing specs. :-) JR [/QUOTE]
