Best Home Theater Power Conditioners

1. Furman Power Conditioner SS6B

There is no question about the reliability of the Furman power conditioner. The SS6B comes in both the standard and vertical strip designs. It plugs into the wall via the 15-foot power cord, which is longer than many other surge protectors.

You even have the option to turn the Furman SS6B on or off with the illuminated power switch. Not only that, but the SS6B also possesses a circuit breaker and six outlets — enough for most households.

The well-built power conditioner is outfitted with EMI/RFI noise-canceling effects for home theaters to eliminate any static or background noises.



2. Accell Powersquid

The Accell Powersquid power conditioner is a great option to match equipment. It also takes up less space. 

The smaller profile is due to the lower number of outlets it provides. It also has a shorter power cord of only 6 feet, which makes it a suitable choice for smaller spaces.

The outlets have a special flexible cord design that allows them to bend to suit your setup. For a smaller power conditioner, it still protects against 600 joules, which is not bad at all.

The product was tested and certified for safety by ETL. One of the best parts of the power conditioner is the equipment warranty of 5 years.



3. CyberPower CSP600WSURC2

Available in black and white, the CSP600WSURC2 is a heavy-duty power conditioner that has 2 USB ports. There are also more USB port options but they provide less joule protection. 

The design is still a great choice for those who are short on space. The swivel design of the outlets also gives more access in tighter slots.

EMI/RFI filters are present to prevent electromagnetic interference and pop in your high end home theater speakers. The surge protection is all the way up to 1200 joules in the 125-volt version.

CyberPower offers an amazing lifetime warranty for the equipment.



Home Theater Power Conditioner Buyer’s Guide

What does it take to be the best home theater power conditioner? Aside from being a reliable surge protector, the best power conditioners have to offer an additional layer of convenience. Follow our expert team’s guide below to find the right power conditioner.

Power Conditioner Build

For something that is supposed to protect your home theater systems and home theater equipment, your power conditioner should be able to handle high current flows. The Furman ssB6 and the Furman M-8X2 have excellent power factor technology to be sure you not only get noise filtration, but also clean power surging through the outlet banks.

The power strips can be standard, which is a more rectangular design but also linear, or vertical, which is a longer design that places the outlet banks side by side. Either build will have protection against anything weather-related such as lightning strikes. 

Power conditioners do more than we give them credit for. They are often subjected to scrapes, impact and falls. To be sure they can withstand any damages, look for ones made of heavy-duty materials.

A strong power conditioner should also have spike protection to ensure the safety and security of your electrical equipment. The one thing most people look for is the stability of power fluctuation. In your search of the best power protector, understand that it’s not only overloads that can damage your system, but also low currents as well.

Find the right voltage the power conditioner is capable of for the right power management. Power monitoring of the incoming line voltage will also help with surge suppression.

The right design and built will also give the best surge protector the ability to suppress electrical interference, which is also referred to as noise filtration. Some even have filtering of noise from the AC line for your home equipment such as vacuum cleaners. 

Make sure your new surge protection equipment also comes with AC power filtration. The AC power filtration will keep electrical spikes and power flows from entering your power strip enclosure. This will guarantee your audio-video quality is not affected.

A 15 amp [1] capacity electrical conditioner is common on the market. 15 amp conditioners will protect against most power surges and offer enough safeguarding for regular setups. If you want to go higher than a 15 amp, there are also 20 amp models available.

Then there is the color and appearance. While neither will have an effect on the efficiency or build of the product, it’s advantageous to have your pick of two different colors to blend everything together nicely. It won’t call attention to your setup and won’t be an eyesore. 

Outlet Number

The number of outlets the outlet banks need to be high current outlets to prevent dirty power. Dirty power is something irregular in the currents delivered to your home theater equipment such as voltage variations. 

However, many outlets you opt for depends on what equipment you need to connect. For this reason, it’s important to count the number of outlets you need. The Furman M-8X2, the Panamax, and other high-end to mid-range products should offer at least 5 to 6 outlets. If you need more, there are plenty of models from these brands that can offer up to 8!

Cord Length

With details to consider such as the power quality, voltage, power supply and the amp capacity from the power strips, many people forget to consider the cord length. To decide on the appropriate length, you have to think about where you intend to plug it in, the size of the room and how far you need it to be from the power outlet. 

The power cord should not be wrapped around any furniture and shouldn’t be pulled. There are options anywhere from 3 to 15 feet or more to accommodate any room size. The Furman models offer longer cables, with our experts’ first suggestion going up to 15 feet!


The setup of power conditioners is simple. Just plug in the cord and the cables for your home theater equipment and you’re good to go. But the best power conditioners offer more than extra outlets. The term surge protector isn’t for nothing so you need to take a closer look at the power conditioning abilities that may impact the setup.

Your equipment should be for both audio and visual uses, which means you should place the power conditioning tool close to your TV and soundbar. Before you plug everything in, double check the voltage regulation. While some power surge protectors come with extreme voltage shutdown, our team advises against testing its limits.

Extreme voltage shutdown is a feature that will turn off the power conditioner when the power supply is too great. The amount for the power supply should be labeled on your product. If your power conditioner requires an amplifier, then there is a greater chance of a voltage surge, so be extra careful when plugging in an amp.

Three-in-One Approach

What is a three-in-one approach? It is a feature that you need to have. A power conditioner that has a three-in-one approach will not only give protection to all of your devices but also enhance the quality of their performance. The three-in-one refers to three abilities: protect your devices, cancel noise, and correct the voltage. 

For example, Furman is well-known for making power conditioners. The Furman brand is known to have the most advanced technologies for power conditioning such as linear filtering technology, protection against extreme surges, different amp power supply conditioner, a battery backup, and noise filtering.


You don’t need to spend a fortune, most mid-range products will give you the right amp power conditioner. Your expensive equipment deserves the right protection, so don’t shy away from spending more for high-end voltage monitoring capabilities to ensure superior performance.

Advanced features can affect the price of the home power conditioners. High-quality surge protection, a higher amp power supply conditioner, noise filtering, automatic voltage monitoring, are all features the best power conditioner will offer for all your home theaters and home studios. 

For example, Furman surge protectors are sought after because of their affordable price and impeccable quality.

Home Theater Power Conditioner Advantages

We’re sure there are times when you have blown out your audio devices or computer equipment without a power conditioner, but your sensitive equipment will not only be protected, but also enhanced.

Is a power conditioner the same as a surge protector?

No, a power conditioner is not the same as a surge protector. A power conditioner cleans up the power to ensure you get even currents while a surge protector controls the amount of fluctuations and prevents irregular ones from coming in to protect all your equipment.

Do power conditioners improve sound quality?

Yes, power conditioners improve sound quality in your equipment. Power conditioning means the device cleans and stabilizes the current so there are no sudden pops or in audible sections of the audio emitted from your gear.

Do power conditioners reduce noise?

Yes, power conditioners reduce noise, but they don’t eliminate it completely. The components in the best power conditioners can have noise attenuation, which reduces the interference from the equipment you have plugged in. This includes tools from the AC power lines.

When should you use a power conditioner?

You should always use a power conditioner to protect all your equipment from an AC power line electrical surge and all the other irregularities that may come to affect your gear. Having a power conditioner will also give your home theaters and home studios a longer lifespan.
