Power conditioners are devices designed to protect audio equipment from power grid events such as voltage spikes, blackouts, and brownouts. They also improve sound quality by filtering out noise and unwanted radio frequencies. Some people believe that power conditioners improve the sound quality of their audio systems, while others argue that they do not make a significant difference and can even restrict dynamics and kill the music. The Furman Elite 15i and Belkin Pure AV PF60 are examples of power conditioners that some users have found to improve their system's sound quality.

What You'll Learn
Power conditioners can protect audio equipment from power grid events
The primary purpose of a power conditioner is to protect audio equipment from power grid events. Power conditioners filter, improve, and stabilise incoming AC power, especially during voltage spikes. They are designed to protect audio gear such as mixers and power amplifiers from voltage spikes, blackouts, or brownouts.
Power conditioners can also improve sound quality by reducing unwanted noise and interference. For example, a high-rejection RF interference filter can keep high frequencies and AM radio signals from contaminating audio signals. This can be particularly useful in a studio setting, where unexpected noises can blast through speakers, ruining audio mixes.
Some users have reported improved sound quality after using power conditioners. One user noticed a "very appreciable difference" in sound quality when using a Panamax conditioner with their Paradigm Studio 60s and pioneer elite receiver setup. Another user reported that a Furman Elite 15i power conditioner significantly improved the sound of their system, reducing buzzing from large toroidal transformers.
However, other users have found that power conditioners can negatively impact sound quality. One user found that power conditioners and filters "ended up subtly killing the music via transient edges and restricted dynamics". Another user reported that a PowerPlant Regenerator constricted their soundstage.
Overall, while power conditioners can protect audio equipment from power grid events and reduce unwanted noise and interference, their impact on sound quality may vary depending on the specific equipment and setup.

They can filter out unwanted noise and radio signals
The primary purpose of a power conditioner is to filter, improve and stabilize incoming AC power, especially during an AC power voltage spike. Power conditioners can protect audio equipment from damage resulting from power grid events such as voltage spikes, blackouts, or brownouts.
Power conditioners can filter out unwanted noise and radio signals, preventing them from contaminating audio signals. This is particularly important for audio professionals who may be mixing audio and want to avoid the sudden blast of an AM radio signal through their speakers. A high-rejection RF interference filter is used to keep unwanted noise, such as high frequencies and AM radio signals, out of the power line.
One user reported that a power conditioner cut out random radio stations that would otherwise come through when they turned off their source and turned up the volume. Another user, however, reported that power conditioners ended up "killing the music" by restricting dynamics and transient edges.
Power conditioners can also provide robust surge protection, which can be important in protecting expensive audio equipment. While some power conditioners may improve sound quality, others may not, and some users report no noticeable difference when using a power conditioner.

They can improve sound quality, but this is not guaranteed
While power conditioners are primarily designed to protect audio equipment from power surges and voltage spikes, some users have reported an improvement in sound quality after installing one. One user noticed a "very appreciable difference" after using a Panamax conditioner on their Paradigm Studio 60s and pioneer elite receiver setup, with the improvement being particularly noticeable on Korn's "Shoots and Ladders". Another user reported a "big improvement" in sound quality after purchasing a Furman Elite 15i power conditioner.
However, it's important to note that not all users experience the same sound quality enhancements. One individual who tried the PowerPlant Regenerator conditioner found that it "slightly constricted" their soundstage. Similarly, another user shared that every power conditioner they had used had ended up "subtly killing the music via transient edges and restricted dynamics".
The impact of power conditioners on sound quality may depend on various factors, such as the specific equipment used, the setup, and the unique characteristics of the power source. In some cases, the perceived improvement in sound quality could be attributed to factors other than the power conditioner itself, such as better connections or the elimination of radio frequency interference.
Overall, while power conditioners have the potential to enhance sound quality in certain situations, this outcome is not guaranteed and can vary depending on the specific circumstances.

They can be used to protect against power surges
Power conditioners can be used in conjunction with surge protectors to protect against power surges and improve sound quality. While power conditioners do not provide EMI/RFI shielding like surge protectors, they can be useful in filtering out "noise" transmitted through electrical lines, which can cause static or buzzing in speakers and electronics.
Power surges can be costly and damaging to devices, slowly destroying internal circuitry over several months. To protect against power surges, it is recommended to have multiple layers of protection, such as whole-house surge protection and point-of-use surge protectors with power conditioners. Whole-house surge protection can be installed between the street power lines and your home, or between your meter and breaker box, safeguarding your appliances from spikes and surges.
Point-of-use surge protectors with power conditioners are installed at individual outlets and shed excess voltage through the ground in the event of a power surge. These devices also have noise-filtering capabilities, ensuring that your electronics run at peak performance. There are two types of point-of-use devices: less expensive models that will be destroyed internally during a surge but will preserve your gear, and more expensive models that can handle all but the most extreme surges without being destroyed.
By combining whole-house surge protection with point-of-use surge protectors and power conditioners, you can effectively protect your audio and electronic equipment from power surges and potentially improve sound quality by reducing static and buzzing caused by electrical "noise".

They can be used to power multiple items
Power conditioners are designed to protect audio equipment from damage caused by power surges, voltage spikes, blackouts, and brownouts. They can also improve sound quality by reducing electrical noise and radio frequency interference (RFI).
While some people believe that power conditioners can enhance sound quality, others argue that they can subtly kill the music by restricting its dynamics and transient edges. However, a power conditioner can be beneficial if you need to power multiple items.
For example, the Belkin Pure AV PF60 is a rack-mountable option that can power numerous devices. It also has the advantage of being switchable, allowing for convenient control over the connected equipment. This feature can be particularly useful if you want to leave certain equipment on or off without affecting the entire setup.
Another consideration is the increasing use of mobile devices in audio setups. For instance, a musician in a studio might want to play an audio clip from their phone, but the phone battery is dead. In such cases, having a power conditioner with front-facing USB ports can be incredibly useful. It allows for easy connection and charging of mobile devices like phones and tablets, ensuring that audio clips or other content can be accessed and shared efficiently.
Additionally, some power conditioners offer multiple outlets, enabling you to power and protect multiple items simultaneously. This feature can be advantageous if you have a setup with various components, such as a mixer, power amplifier, or other audio gear. By plugging these components into the power conditioner, you can ensure they receive stable and filtered power while also protecting them from potential power-related damage.
