[QUOTE="thch, post: 2585501, member: 562032"] the maximum voltage gain the amp can support without artifacts is based upon supply regulation and output impendace of the amplifier. if the supply can be reduced, then to garuntee no clipping (if such is the goal), the gain must be set based upon these low line conditions, giving a slightly lower gain setting. if the output impedance is high, then at full scale output, the load will pull down the signal a bit, reducing the gain a bit. the penelty for such a small amount of clipping is generally low. the DMM method does match input sensitivity indirectly. the input is assumed to be "the desired input", and the output is adjusted (by gains) to give "the desired output". if done, this means full-scale on the input gives full scale on the output. which is not to say there are not other uses for gains. level matching can be accomplished. a user might even get an SPL meter and adjust it such that a certain volume setting gives 110dB, thus setting the volume's range based upon what they want to listen to, and not the capabilities of the equipment.
