Folks - been trying a different speaker in my system.... it claims 94dbW sensitivty, a lot more than the 86dbW claimed by my usual ATC SCM12.

Now, I thought this would mean turning the volume down a little bit on my amplifier, but quite the reverse, I am having to turn it up a little bit (normally 68-69 on the digital dial when I listen to the ATCs, now listening at 72.5 to achieve same subjective volume level).  I find this surprising.  Does it mean the claimed sensitivity is nonsense?  The speakers are Living Voice Auditorium II.  thanks.
