 +==== Rant: About HiFi... ====
  
 +"A chain is only as strong as its weakest link" everybody knows, and indeed it applies across many domains, form actual metal chains to security((Both the physical and the digital ones.)). But it doesn't really apply well to HiFi, that is the full //chain// from source to your ears.
 +
 +Pick your favorite song and imagine you have a perfectly decent recording of it on a CD.
 +
 +Now your first setup consists of:
 +
 +  * ''Player'': a semi-broken crappy knock-off, which requires description:
 +
 +So it //works//, technically... you put the CD in and... Well the 50((Or 60, if you're elsewhere.)) Hz buzz is constant, and the player doesn't really start outputting anything below 200 Hz. The mids get through and surprisingly, they do have a nice flat reproduction. And then you get above 5 kHz and stuff gets //very unpleasant//: seemingly random spikes, constant hiss, and during the quiet sections you seem to notice white-noise too. Yes, this is a really crappy player.
 +
 +  * ''Amplifier'': a decent one; reproduces 10 - 20k Hz without any shame
 +  * ''Speakers'': also decent, but this time a set; 50 - 10k Hz, power rated adequately to the ''Amplifier''
 +
 +**So what do you get?** A room full of noise where you don't really want to be. Everything shakes, the high-pitched noise is painful, and your favorite song is just lost in this misery.
 +
 +So is this chain as bad as it's weakest link, the ''Player''? //No//, it's actually **worse** as a whole. And to see that...
 +
 +Now your second setup consists of:
 +
 +  * ''Player'': the same! as crappy as ever
 +  * ''Amplifier'': well it's there built-in into your mediocre boombox; sanely engineered so it has a strong band-pass filter for 500 Hz - 5 Khz
 +  * ''Speakers'': they're built-in too, and matched to the 2x2W of actual((Your mediocre boombox is not crap, it didn't come with "200 W P.M.P.O" sticker on it. Yes, this is from experience.)) output power
 +
 +**So what do you get?** Your song! It's noticeably cut-off at both ends, but what you hear is //listenable//, more even, //enjoyable// if you treat it as background music and get your mind onto other things. It works. The two other components are now objectively //worse// than the ones from the first setup, and yet your overall experience is //much better// now. See?
