As far as I know sensitivity is the input level for which the power amp maxs out its power. it would also be usefull to know max power/input level @ 1% THD

Stefanoo, is it so hard for you and go to Nelson's web page and see all the spec yourself?
If you are not good at google, I can do it for you:
https://passlabs.com/products/amplifiers/x.5/x250.5
scroll down and click with your mouse on full spec...all the information is there.

it takes 2.24 volts on input to reach 250 watts into 8 ohms at 1% distortion with 64 volts on output which is gain of 26 dB

Nice of you to provide a link, but you linked to the X250.5, not the X250.

Probably not a lot of difference

Adason you are a genius I could have never found the X250.5....wooww!!

Actually if you would read the thread better before firing your brain's cells you might even have a chance to give the right answer!!!!! Hard to believe uhm?

The X250.5 has a different gain thus a slighly different higher sensitivity.
