I should post in this thread since I keep losing it within my bookmarks and I always want to refer back to this. XD
I find myself digging for it a lot, too lol

Are you sure about K271/272 sensitivity? Going by Tyll's results, they ought to be at 107-110-ish dB/V. Spec is 104.

Some have raised concerns with 110 dB SPL being too loud. Well, that is just the absolute highest SPL you can reach with a full-scale 500 Hz tone and the volume set to max.
If you don't mind me asking, how was the gain calculated? It seems to be 104 - S@1V.
The gain calculation assumes a source output voltage of 2 Vrms. For lower voltage (portable) sources, obviously more gain is needed.
His old calculations were completely wrong. It's best to ignore them.
Is there any way to know your db without a measurement device?
Add to the sensitivity specified as x dB SPL/1 Vrms the following: 20*log10(V)
