Does my amp have enough juice to power my speakers?

Well, that was fun.  Kind of all over the map.  I'm confused.  So you are running these speakers with the Line Magnetics.  And they sound heavenly, except when they don't.

How about the room dynamics?  Is the room over damped?  Line Magnetics makes a fine product and the 22 watts is surprisingly strong.  How far away are you sitting?  Do you need ear bleed levels?  What time of the day/night does it sound heavenly?

Inclined to agree power quality is better at times and worse at times.

At 100 db you ears will check out bad one of these days .
The greatest jump in doc numbers is ear guys which have increased
10X since the 60's . Young docs know that's the sure road to wealth
for doing little or nothing .

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. 

love drawing a conclusion based on a sample of one....

from my experience in managing manufacturing operations across the globe for thirty years, the injured are often convinved of the exceptionality of themselves, PRIOR to the injury....
