If you own an AV receiver, you're halfway to a cinematic home experience—but the right accessories finish the job. From cables that carry lifelike sound to power gear that protects your investment, the small things make a huge difference. In this guide I’ll walk you through the must-have audio receiver accessories, explain how to pick them, and point you to trusted US retailers where you can buy them. Ready to tune up your setup?
Your receiver is the brain of a home theater, but like any brain, it needs good connections and protection to perform at its best. Poor cables, weak power protection, or a sloppy speaker setup can choke sound quality and rob you of detail. Think of accessories as the veins, arteries, and safety gear that keep the whole system healthy—because they are. Choosing the right accessories helps you squeeze more performance out of existing speakers and future-proofs your system as you upgrade.
HDMI cables are the lifeline between your streaming box, Blu-ray player, game console, and receiver. For modern 4K/120Hz gaming and high-bandwidth features like VRR and ALLM, aim for HDMI 2.1-rated cables. If you’re only running 4K/60Hz, a high-quality HDMI 2.0 cable can work. Always choose cables long enough for your setup—6 to 10 feet is common for living room runs—but avoid excessive coiling which can cause signal issues.
Speaker wire quality matters less than gauge and termination. Use thicker wire (lower AWG number) for long runs: 12 or 14 gauge for runs over 25 feet, 16 gauge for short runs under 10 feet. Terminate with banana plugs or spade connectors for a clean, corrosion-free connection. Think of speaker wire as the highway for sound—keep it wide and direct to avoid traffic jams.
Subwoofers use an RCA line-level cable to preserve low-frequency detail. A well-shielded, low-loss cable avoids hum and noise, especially when the cable must run near power cables. For typical living rooms, a 10- to 25-foot cable is common; measure before you buy so you’re not stretching or coiling the cord in ways that invite interference.
Many receivers include automatic room calibration, and the included mic is fine for baseline tuning. If you want more precise results, or to run manual tweaks, consider a calibrated measurement microphone and software. These tools help you tame room modes and ensure bass is tight, not boomy—kind of like using a level when hanging art instead of guessing by eye.
Protecting your AV gear from spikes and brownouts is critical. A high-quality surge protector with a high joule rating is basic insurance. For audiophiles, a power conditioner can reduce AC noise and provide cleaner power. If your setup includes expensive amplifiers and preamps, think of power protection as a cheap insurance premium compared to replacement costs.
One remote to rule them all? A programmable universal remote can simplify control, especially with multiple devices. Advanced smart remotes or apps can integrate with voice assistants for hands-free commands. A universal remote turns a clutter of devices into a single intuitive experience—like swapping a messy desk for an organized workspace.
Proper ventilation is important—receivers generate heat. Use an AV rack or a dedicated shelf with airflow to prevent thermal throttling. Racks also keep devices organized and reduce cable strain. When sizing, allow a few inches of clearance above and behind the receiver for ventilation and cable bends.
Best Buy is a convenient retailer with hands-on demo areas for home theater gear and a wide selection of AV accessories. Their stores let you see and compare cables, remotes, and surge protectors in person. Online, Best Buy often bundles accessories with receivers which can be a good way to save on essential items like HDMI cables and speaker wire.
Amazon carries virtually every accessory and price point, from budget cables to audiophile-grade gear. Prime shipping is handy for last-minute purchases, and the user reviews can help you spot reliable brands. Just be cautious with third-party listings—check seller reputation and product specs carefully before you buy.
Crutchfield is a favorite among enthusiasts for its deep AV expertise, excellent customer service, and detailed product pages that explain compatibility. They provide real-world advice on speaker wire lengths, cable types, and calibration tools. Crutchfield also offers expert setup guides and can tailor recommendations to your specific receiver model.
B&H is a go-to for pros and hobbyists alike, especially when you want professional-grade cables, microphones, and power gear. Their catalog includes measurement mics, power conditioners, and premium HDMI interconnects. Fast shipping and a strong returns policy make it a reliable option for high-end accessory purchases.
Monoprice is an excellent choice for high-value cables and connectors at sensible prices. They’re known for straightforward specs and dependable quality on HDMI cables, speaker wire, and banana plugs. If you want performance without premium branding, Monoprice is often where enthusiasts look first.
For basic accessories—speaker wire, surge protectors, and entry-level HDMI cables—big-box retailers like Walmart and Target offer convenience and low prices. These stores are ideal when you need a budget replacement or a quick emergency cable. For specialty items or audiophile components, you’ll want to shop elsewhere.
Sweetwater and Audio Advice cater to musicians and home theater enthusiasts respectively—both supply higher-end accessories and personalized advice. Sweetwater is great for sound professionals and studio-quality gear, while Audio Advice focuses on home theater integration, speakers, and custom installations.
Measure twice, buy once. For speaker wire, measure the path the wire will follow and add a few extra feet for slack and routing—typically add 2 to 5 feet. For HDMI and RCA runs, keep cable lengths moderate: under 25 feet for HDMI is ideal to avoid signal degradation without active repeaters. For speaker gauge, use 12 AWG for runs over 50 feet to maintain bass control; 14 AWG works well up to about 30 feet, and 16 AWG is fine for short runs under 10 feet.
Spending more doesn’t always translate to audible improvement, but there's a point where upgrades make sense. Start with good, properly sized basics—correct gauge speaker wire, well-shielded HDMI, and solid power protection. If you’re running a high-end speaker set or long cable runs, upgrading to premium cables and a power conditioner can yield clearer detail and tighter bass. If your speakers and receiver are entry-level, invest more in room treatment and calibration than ultra-premium cables.
Ready to install? Here’s a short checklist that makes setup painless: 1) Label each cable before you connect, 2) Route power and signal cables separately to minimize hum, 3) Leave at least 3 to 4 inches of clearance around the receiver for airflow, 4) Dress speaker wire with cable ties and avoid sharp bends, and 5) Run the receiver’s auto-calibration, then fine-tune manually if needed. Simple habits during install pay dividends in reliability and sound quality.
Planning for the future helps avoid frequent upgrades. Buy HDMI 2.1 cables if you think you’ll adopt next-gen consoles or 4K/120Hz sources. Choose a power conditioner with extra outlets and enough wattage headroom for future components. Opt for modular racks that allow extra shelves. These choices cost a bit more now but save hassle and expense later—like building a solid foundation before adding the roof.
There are a few traps I see often: buying cables that are too long or too short, underestimating speaker wire gauge, chasing superficial “audiophile” marketing without matching components, and equating price with compatibility. Also avoid running signal cables parallel and close to power cables—hum follows nearby like static cling. Measure, plan, and match components rather than guessing based on shiny packaging.
Bundles sold at retailers can be convenient if they include the essentials: HDMI, speaker wire, and surge protection. They often save money and time, especially for first-time builds. But bundles can include items you don’t need or cables of subpar length. If you have a unique layout or plan to upgrade parts independently, hand-picking individual components gives you better control over quality and compatibility.
Maintenance is simple: keep vents dust-free, inspect speaker wire terminations for corrosion, and periodically re-run automatic calibration after major furniture moves. If you live in a dusty house or near a construction site, schedule a clean every 6 to 12 months. Treat your AV system like a car—regular small checks prevent big problems later.
Accessories are the unsung heroes of a great listening experience. With smart choices—proper cable lengths, gauge-appropriate speaker wire, decent power protection, and careful retailer selection—you’ll hear the benefits immediately. Whether you shop at mass-market stores like Best Buy and Amazon, specialty retailers like Crutchfield and B&H, or value brands like Monoprice, the right choices will keep your system sounding fresh and reliable for years.
Ready to upgrade? Start by measuring your space, noting your gear list, and picking the essentials: HDMI, speaker wire, and a good surge protector. From there, dial in calibration and consider premium power or measurement tools if you're chasing the last 10% of performance. It’s amazing what a few smart accessories can do for your system.
Conclusion: Great sound isn’t just about the receiver and speakers—it’s about the cables, power, and setup choices that connect them. Invest in the right accessories, buy from reputable US retailers that match your budget and needs, and take a little time with installation. Your ears will thank you.
