Tips:
  * Use EQ as an almost free upgrade to your speakers
  * Avoid soundbars, you can get active speakers for the same money
  * Avoid newer home theater receivers, changing advanced settings might need a TV
  * Avoid headphones, instead make sure you have physical bass and correct stereo imaging
