What am I missing? Pre/power gain and input sensitivity.

I’ve read a few posts about power amps with lower gain needing a pre with additional gain, but no one seems to mention input sensitivity in those conversations. If my source outputs 2V and my power amp input sensitivity is only 1.2V then whether the power amp gain is 16dB or 26dB my pre amp is attenuating the signal and the amount of gain on the pre doesn’t matter at all. With a given set of speakers, to get the same SPL with 2 different amps they should just need to output the same voltage, regardless of how they get there.

Am I missing something?

See, here's the thing about the internet: zero editorial standards.  Anyone can post anything. On this site your odds of being read are actually higher the greater the BS. Our #1 has 21k posts and when you ask if someone can find even one of value the question is removed and the 21k grows to 22k. 

So yes you are missing something: the necessity of DYODD. And no, you are not missing something. They are.
