Acuhorn 125 with Leben 15w amp

The Leben is a beautiful sounding piece.  However, I am not sure if it will have the slam you might want for movies?  15 watts runs out quickly on action films.  Acuhorn even states on their web site that their speakers don't have "slam".  
96db/1 watt, 99/2 watts, 102/4, 105/8, 108db/16 watts.  THX ratings are 110 or 112 db.   This set-up will play movies but not do you justice.  The Klipsch may do a tiny bit better but not much.
I use my 10 watt amp for music and my 325 wpc amp for movies.

THX ratings are 110 or 112 db
I probably misrepresented the movie factor - I merely need it to support the occasional movie - not be a cinematic experience and just something better that the TVs built in speakers.
the amp is mainly for headphone use when I am being thoughtful of neighbours - but occasionally it does lighter music duties.

  The Leben is a beautiful sounding piece.

This to me contradicts what I see in bench tests, I wouldn't let an amp out that looked like this on final production tests. 
High frequency accentuation that starts at around 6khz and climbs to 45khz, which is then replicated in the square wave shots as severe ringing. All this points to me like a output transformer that isn't very well designed for stability.
Not that I've heard one but are you sure this amp doesn't sound a little HF accentuated?
