Putting together a great home theater system can be simple — you just need to team up a few key components, some of which you probably already own. As you think about which pieces you need, keep in mind that along with buying new products, you might end up replacing some existing gear as well. For example, if you want to watch high-definition TV programming, you may decide the time is ripe to replace your 10-year-old TV with a new high-def model.

A TV
A gorgeous picture is the focal point of many home theater systems. Most of today's TVs are digital TVs — they offer a stunning picture, and many sets can show the high-resolution picture you get from HDTV.

A DVD player, Blu-ray Disc™ player, & other home theater sources
Home theater relies on sharp, colorful video and Dolby® Digital-encoded audio. A DVD player is by far the most common source of home theater audio and video, because most DVDs offer high-quality images and digital surround sound. If you are replacing an older DVD player, be sure your new model can send a progressive video signal — it really makes a difference on today's digital TVs.
If you have an HDTV, you may want to consider a Blu-ray Disc™ player. This high-definition disc format lets you take full advantage of your high-def television's display capabilities. For more information, check out our article about Blu-ray players.
Other top-notch home theater sources include HDTV programming, which delivers high-resolution video and digital audio, and video game consoles, which offer impressively crisp images and high-impact surround sound.

A home theater receiver
In order to enjoy surround sound, you'll need a home theater receiver. A receiver acts as the control center for audio; it processes audio signals, amplifies them, and sends them to your speakers. All home theater receivers can process and amplify multichannel surround sound as well as stereo audio, because they have built-in surround sound decoding. Most of today's home theater receivers can also transform a stereo signal into a surround sound signal — that means you can hear VHS, TV, and CDs in surround sound too.
Some people use their home theater receiver to manage video as well as audio — by running all their video signals to their receiver, they can make a single video connection from their receiver to their TV and simplify everyday use. It's a great option if you want to connect multiple sources, like a cable box, a DVD player, and a video game console or two, to your home theater system. Then whenever you want to watch a DVD or play a video game, you just have to press a button on your receiver's remote to switch to the right inputs, without having to switch inputs on your TV.

Speakers and a subwoofer
To faithfully re-create the larger-than-life, wraparound excitement of movie theater sound, you need at least five voice-matched speakers and a subwoofer. Some people opt for six or seven speakers and a subwoofer, so they can hear even more channels of surround sound. If you buy a pre-assembled system, you won't have to worry about voice-matching. But if you put together your own system, then make sure you buy from the same family of speakers.

Cables, power protection, and A/V furniture
Often, people forget about essential accessories. They end up rushing out to the store in the middle of setup, or making do with a cable that isn't really suited to the purpose. The result? Extra hassle, and a real risk of missing out on the system performance they paid for. You can avoid that by planning out your system before you buy, accessories and all.

Cables
You'll need speaker cables, audio cables, and video cables. You may already have some cables you can use. Just don't forget that very old or very cheap speaker cable can degrade your sound quality, the same way very old or very cheap speakers just don't sound good. Also, "freebie" audio and video cables that come in the box with a component can also result in lower-quality sound or picture; reduced picture quality is especially noticeable with today's high-end TVs, which aren't kind to static or picture flaws.

Power protection
It makes sense to use a power protection unit to safeguard your investment from lightning strikes and power surges. Some home theater fans choose a power protector with built-in line conditioning to ensure cleaner power, a better picture, and more accurate audio.

A/V furniture, speaker stands, and speaker brackets
Depending on your room's size and shape, and the equipment you choose, you may need some stands to place your gear on. Be thinking about whether you'll need anything like this ahead of time, so you can avoid putting your TV on a couple of old crates, or having small surround speakers on the floor behind your sofa where you can't really hear them.
