We listen to so much audio sitting at our computers, whether it be a Youtube video, your music library, or watching something on Netflix, we may as well have some nice speakers to listen on. Sure you can buy bookshelf speakers and hook up an amp and then you need to find room on your desk to fit everything. Or you can buy some speakers designed for the desktop with an amp built in. They range from junk to really good. Read that as cheap to expensive.
