Designing a home theater system requires choosing the right audio/video (AV) components to power your speakers and display your favorite content. There are several key components to consider including amplifiers, receivers, and processors. In this blog post, we will break down each of these component types, the major features to evaluate, and tips for selecting the best option for your needs and budget.

Amplifiers

Amplifiers are dedicated devices that only focus on amplifying and powering speakers. There are a few main types of amplifiers to be aware of when shopping.

Integrated Amplifiers
Integrated amplifiers combine a preamplifier and power amplifier into a single unit. They handle all of the amplification duties but lack any other inputs or functionality beyond volume control. Integrated amps are a compact option ideal for smaller stereo setups with limited sources. Top brands like Marantz, Yamaha, and Cambridge Audio offer quality integrated amplifiers at various price points.

Multi-Channel Amplifiers
If you have a setup with surround sound speakers, a multi-channel amplifier allows you to power all of your speakers individually. Models range from basic 5-channel amplifiers up to 11-channel versions that can power ATMOS overhead speakers as well. Key specs to check include the power output per channel, supported formats like Dolby Atmos, and number of input channels. Reputable manufacturers for multi-channel amps include Anthem, Emotiva, and Onkyo.

Power Amplifiers
Power amplifiers focus solely on amplification without any tone controls, inputs, or preamplifiers. They require a separate preamp or receiver for sources and volume control. Power amps offer the cleanest amplification but lack versatility as a standalone solution. Brands like Rotel, Bryston, and Parasound make high-quality power amplifiers suitable for audiophile setups.

Choosing an Amplifier
When choosing an amplifier, consider your speaker configuration, room size, and power demands. Integrated amps work well for basic stereo while multi-channel models enable surround capabilities. Power amps provide the purest amplification if paired with an appropriate preamp. Budget will also factor into your selection of features and brand.

Receivers
Receivers are the most versatile type of AV component as they combine amplification, source switching, and surround sound processing into a single unit. Here are the main receiver types:

Basic Receivers
Entry-level receivers offer the basics like 5-channel amplification and a few HDMI ports for streaming devices or gaming consoles. They lack advanced room calibration and higher-end codec support but provide simple home theater functionality on a budget. Popular brands at this level include Yamaha, Onkyo, and Sony.

Mid-Range Receivers
Moving up from basic models, mid-range receivers have more powerful amplification, multi-Dimensional surround formats like Dolby Atmos, advanced setup features, and support for higher resolutions like 4K. Companies like Denon, Marantz, and Pioneer often release some of their best value receivers at this price point.

High-End Receivers
Flagship receivers deliver reference-quality amplification, the latest surround technologies, extensive calibrations tools, and support for codecs like DTS:X. They also offer networking features and integrated smart platforms. Audiophile brands that make high-end receivers include Anthem, Arcam, and Bryston. These receivers provide cinema-grade home theaters but come with cinema-grade pricing as well.

Choosing a Receiver
When selecting a receiver, think about your speaker configuration and sources. Mid-range models offer excellent value while high-end options maximize performance. Consider room for future upgrades too. Stick to reputable brands and check user reviews to get the best receiver for both your current and long-term needs.

Processors
For the most advanced home theater setups, a dedicated processor provides ultimate control and calibration. Here are the main types:

Entry-Level Processors
Entry models provide basic 7.1 or 5.1.2 surround processing for modest home theaters on a budget. They lackEQ tools and advanced formats. Brands like Yamaha and Denon offer decent starting processors.

Mid-Range Processors
Mid-tier processors have more extensive calibration options, support for new immersive audio formats, networking features and app-based control. Pioneer and Anthem make highly regarded mid-range processors.

High-End Processors
Flagship processors deliver reference-quality room calibration and surround virtualization. They offer support for the latest 3D audio technologies, robust EQ options, flexible setup tools and seamless integration into complex home automation systems. Top brands creating high-end processors include Datasat, Trinnov and Bryston.

Choosing a Processor
Processors are best for dedicated home theaters with multiple subwoofers and speakers placed throughout the room. Consider your current and future needs regarding room size, speaker placement and desired audio formats when choosing. Entry models work for basic setups while high-end processors maximize performance in advanced theaters. Stick with reputable brands offering excellent calibration.

Putting it All Together
Hopefully this blog post has helped explain the key differences between amplifiers, receivers and processors while providing tips on choosing the right component for your home theater application and budget. Consider factors like:

Speaker configuration and power needs
Sources and inputs you will be using
Desired surround formats and future-proofing
Room size and acoustics
Calibration and customization importance
Budget limitations
A receiver is a great versatile choice for most setups providing both amplification and centralized control in one box. But for dedicated theaters an external amplifier or processor may be preferable. Do your research on features, reviews and manufacturer reputation to land on the AV component that delivers an exceptional entertainment experience for your needs. With the right selection, you'll be well on your way to building an amazing home theater system.
