The stuff costs a lot of money. It can make a mess of a room. Putting it to full use can drive other family members...not to mention neighbors...nuts. The magazines and websites that cater to the trade possess writers who are talented and convincing enough to make you think that your opinions...or shall we say your ears...are less than stellar. In other words, the pursuit isn't exactly guilt-free.
Then again, it ain't like a motorcycle. The worst that can happen to you is a bit of tinnitus, and a hernia from lugging the components around the room in order to find their perfect locales.
