   There are actually sensible people involved in audio, and good quality   
   amplifiers and loud speakers are worth paying for.   
      
   Audiofools pay absurd money for essentially bizarre speakers and   
   amplifiers that don't perform any better than regular good quality   
   stuff, and sometimese perform quite a bit worse.   
      
   I once gave my father some qood quality headphones - Sennheiser 480's -   
   and they performed a whole lot better than the equally expensive   
   headphones that his audio shop in Melbourne had sold him. He was   
   surprised. I snaffled them back after he died - my mother wasn't into   
   headphones.
