Whether you're a parent looking for an inexpensive system for your kids or an executive looking to liven up your office with music, you may want to consider a shelf system. (Peachtree Decco system pictured above.)

You don't need to sacrifice a lot of space to get quality sound. Today's shelf systems are smaller and sound better than they did just a few years ago. They offer convenient, all-in-one music solutions for your office, dorm room, or any other location where space is at a premium.

Shelf systems also look much more refined than they used to. Gone are the days when all shelf systems were big boxes with a lot of flashing lights. Today's sleek, contemporary designs blend seamlessly with modern décor, and look right at home on a desk or in an office.

Some shelf systems give you iPod control via an optional dock. (Onkyo DS-A2x dock pictured above.)

Lots of music options

The compact size of these systems doesn't sacrifice music-playing flexibility. Typically, shelf systems include all the components of a full-size stereo system: CD player, AM/FM radio, an amplifier, and stereo speakers. Most give you an auxiliary input for connecting an additional music source, such as an MP3 player. Some shelf systems let you enjoy the diverse offerings of satellite radio — just add a tuner and subscription. And if you're an iPod® fan, you'll appreciate the iPod connection and control capabilities offered by some newer shelf systems.

Quality sound in a small package

Although they may not sound quite as good as separate, full-size components, shelf systems sound remarkably good for their size. Many of them include some of the same technologies found in separate receivers and amplifiers, such as high-current designs that deliver accurate sound reproduction and greater dynamics. Some models even include things like a tube preamplifier for added warmth in middle and high frequencies, or anti-resonant MDF speaker cabinets for smooth midrange sound.

When comparing one shelf system to another, you may want to look at each one's power output. This figure, measured in watts, tells you how much power the system sends to the speakers. Generally, a system with more power will sound better than a lower-powered one. (Check out our discussion of power ratings in our audio/video receiver shopping guide.)

Easy to set up and use

These all-in-one music systems are super-easy to set up; often all you have to do is plug in the included wires leading to the speakers. They're also designed with ease of use in mind. Many models offer one-touch operation: simply press the "Play" button of the CD player and the entire system springs to life.
