Does my amp have enough juice to power my speakers?

My modified Klipsch Lascalas do not need much power, but when I listen to certain music, at certain levels ( 100db peaks and above ), my ears do appreciate a larger, higher wattage amp. My ears check out fine, btw. Of course I am talking about good clean watts. The playback of cannon shots and explosions ( an example would be from Roger Waters " Amused To Death ", etc., definitely satisfies me more with larger output amps, and needless to say, my system handles it beautifully. Chamber music and some Jazz trios do great with any smaller amp I have, but there is still a " heft " and a " meat on the bones " thing going on with a larger amp. FYI, I drive all of my amps passively. Enjoy ! MrD. 

Schubert, at almost 65, I am experiencing some age and time related issues. Fortunately for me, my ears are still going strong. I traveled the NYC subway system for years; was in a band; a choir; was in the audio business; been listening since 7 years old; and more. At peaks of 100db, although loud, does not compare to a large number of musical performances I have attended during my years. If you look at decibel charts and see what noises are at what levels ( vacuums, lawn mowers, power drills, typewriters ) of a common household, you will see that 100 db can be considered just above the norm, as I am not exposing myself to these levels 8 hours a day. P.S. It is just not ear docs. Living in Florida, with many retirees, I know this first hand. Enjoy ! MrD.
