Headphones! I've recently learned that headphones are the most cost effective way to enjoy the audiophile experience. They even make headphone specific amplifiers. You could probably spend around 300 dollars on a good headphone set up that would cost you in the 1000's speakers-wise.
And honestly I'm surprised it took me this long to realize just how awesome musoc sounds in them, all while not pissing off wife with speakers blaring in the basement.
