Amplifiers...they make the music...loud. Clean. Crisp. Without amplifiers we'd all be listening to live acoustic music like all the poor suckers that lived through all of history until 1907 (the first amplifier was invented then). Just think of all the people with huge horns stuck in their ears, trying to hear the 22 minute flute solo in Beethoven's little known piece, Das Freebirden.
We've had it good for the last 60 years. Amplifiers have improved by leaps and bounds, contributing to hearing loss the world over. The gradual deafening of humanity has been great for the research and development departments of amplifer manufacturers, as well, as increasingly loud music is necessary in order to be heard over the constant ringing in mankind's ears.
If you want your clubbers or wedding guests to know they've had a great night, make sure you pile up the amplifiers in your system. Let tinnitis be your guide!
