One of the reasons I dislike the term "input sensitivity."

Another reason is that it's a relatively useless parameter compared to gain, for example.

Indeed.  I got caught in the input sensitivity trap once early on.  

It's all about gain baby.

Whether it is a PL6.0PFC or PL6.0II is relevant as the ratings are different.  The PL6.0 has a high input sensitivity, one reason you can run a hotter signal into it without clipping.


That's backwards.  Higher sensitivity means you need less input to drive the amp to Full Tilt Boogie.

Of course I think you mean that the sensitivity, as given by that voltage needed to drive the amp to Full Tilt Boogie, is a higher number on whichever amp you say you can run hotter.
I think that in this case we're both right as your second sentence (input voltage for full output) is correct for the general case and my statement was also correct using the terminology in the related product data.

Personally, I'd like to see the gain and maximum voltage/current outputs for amps and a maximum voltage input and impedance for speakers instead of power ratings.  It is really about the voltage and current an amp can deliver (both maximum and for a specific input) and the voltage and current a speaker can handle.
