AV Receiver Buying Tips

Putting together a home theater can seem like a daunting task. So many pieces to think through and connect up! But if you care enough to do your homework and educate yourself, you’ll find it’s not as complicated as it looks. Here’s what goes into your typical viewing room.

Determining amplifier-power requirements for your home theater system.

Power output is often the biggest selling point for receivers and standalone amplifiers. Bells and whistles aside, you can often spend a lot less money for an amplifier or receiver that has a lot less power. While there are several factors that influence an amplifier's sound quality, we're not going to go into many of them in this article. We're going to focus on power. Ideally, an amplifier should be rated with low distortion, measured over the entire audible frequency range and with all channels driven. You should always listen to an amplifier before you purchase it. Whether you should test the 60-watt model or the 150-watt version depends on many factors, including your listening environment, the speakers you'll be using with it, and your listening habits.

It’s easy in this brave new world of Ultra-Uber-HDR-4K HDTV to forget that the sound is still half—yes, half—of the home theater experience. Even if you’re actually smart enough to know that, and you wander into your local big-box electronics store in an effort to improve upon the tiny rear-facing drivers that pass for flat-panel TV speakers, you’re probably in for a knee-deep wade through soundbars and Bluetooth speakers before you stumble onto the audio/video receivers. You remember receivers: Those boxy things? Bunch of buttons and knobs and lights on the front? At one time, people used to called them stereos? “Oh yeah...those,” says the young skeptic festooned with the store logo on his shirt. “I think we still carry a couple of them in that back room over there.”

Oh boy, the times, they are a changin’. With the explosion of integrated soundbar offerings—including some pretentious premium models—it would be easy to dismiss the audio/video receiver, once the great ruler of the home theater world, as an aging relic. Enthusiasts know better...

Selecting audio components is one of the more daunting tasks that any serious home theater enthusiast faces. On the surface, it seems evident that if you just go out and buy the best components you can afford, they’ll sound great with both movies and music. And that’s generally true: A better system will more accurately reproduce the waveforms you feed it, irrespective of whether they come from a movie or music. But it’s often not that simple. While assembling a home theater system that’s equally spectacular with movies and music may be a laudable goal, unless you have unlimited funds, you’ll probably have compromises to make. At that point, you might want to steer the system’s performance strengths one way or the other with the right mix of speakers and electronics. But how do you go about matching these up?
