How loud in DB, Is "cranking it"


Gents;

i just just got a new amp and was Playing my 87 db efficient speakers( Thiel)

My speakers 8 ft apart and I sit 9ft back

I was just playing my amp at "30 watts class A" and I heard 97 db at listening seat.
I normally listen at 70-75 db

I was told the Xa30.5 might not have enough power! In my questions to Audiogon

To me it's WAY more than I need......no issues here. If my amp is considered underpowered, You guys must be nuts!!
lol

So; the question:. 

How loud is " crankin it" for you guys
and
How loud do you normally listen?

100db is cranking at my house and definatley ringing ears,which isnt good for an ole fart like me there already beat of from being a musician ..120 db is painful and very damaging like ac/dc front row next to the pa lol usually 60-80 ish  ...

I think I recall in an article that Eddie Kramer would leave the control room if a band needed to listen to playback above 90 dB. 
czarivey:

The Pass amplifier was reviewed/measured by Stereophile and having just looked up the info it output 332 watts into 2 ohms @ 1% distortion and close to 200 watts @ 4 ohms.

I do not understand what Nelson did with the new design, but it’s a major departure (headroom wise) from the Aleph series.
