What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- High-end fit and finish with a thick, rolled aluminum chassis provides a streamlined look, and the component feels extremely solid
- Improved power stability to audio equipment may result in better audio performance, depending on the type of power supply used in components
- Allows more precision and inner detail to shine through
- Reduces noise floor
- Excellent build quality for its price
Product Considerations
- Limited in terms of power demand and system complexity, with its 300-watt maximum continuous output capacity and six power outlets
- Those with Class A or larger Class AB amplifiers will need to plug their amps directly into the wall outlet, or switch the two optional high-current outlets to the "filter high current" mode—and thereby forego the benefits of power regeneration
- Use of LED indicators rather than a touchscreen provides less information visually, and the unit cannot be connected to the internet to view historical data
- The remote control is required to activate the MultiWave and CleanWave functions
- An additional mains distribution lead to increase the number of outlets ups the effective output impedance and can result in overloading the regenerator
Comparisons (according to reviewers)
- Vs PS Audio PerfectWave PowerPlant 5: The Stellar PowerPlant 3 has less power output capacity, but one-third the impedance, and the reviewer could not detect a definite audible difference between the two models
- Vs Shunyata Research Hydra Delta D6 power conditioner, Audioquest Niagara 3000, and IsoTek V5 Aquarius power conditioner: The choice comes down to either power regeneration from PS Audio, or power conditioning from one of these competitors
Takeaway: The Stellar PowerPlant 3 AC regenerator provides a solid, stable power foundation that can improve audio performance. If seeking clean power for a system, this product might be the right choice.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- PS Audio stands apart by employing a hybrid amplifier design, often combining a vacuum tube input stage with a solid-state output stage, seeking to blend the sonic characteristics of both technologies.
- PS Audio products, particularly power regenerators, are designed to actively regenerate AC power, aiming to provide a clean and stable power source that is independent of the quality of the incoming electricity.
- They emphasize a holistic system design and often tune their components by ear, with active involvement from founder Paul McGowan and engineers who focus on achieving a musically engaging sound rather than strictly adhering to measurements.
- A key focus for PS Audio is making high-end audio accessible, often incorporating generous features, a small form factor and technology trickled down from their top tier offerings into value-oriented "gateway drug" products.

DC Block 6
499
/
Released
2022
The DC Block 6 has been designed to improve the quality of AC electricity that feeds our audio and AV systems. Mains electricity has a fundamental influence on the audio signal as it passes through a system, from source to amplifiers to speakers. The mains supply in a typical home is subject to interference induced by a range of issues, causing the AC waveform to distort before it reaches each component. This creates noise in the audio signal, which degrades sound quality – a situation that continues to worsen with more and more electrical devices being added to the home mains supply.
Audiolab is a hifi brand known for its unique streaming platform from Pixel Magic, which enables over-the-air updates and wide audio format compatibility including DSD. Their amplifiers and components feature distinctive capabilities like HDMI ARC inputs, user-selectable digital filters for sound customization, and advanced filtering technology in their pre/power amps.
Expand Details
Our Summary
Product Strengths
- Eliminates DC offset, reducing transformer hum
- Reduces RFI and EMI contaminants from the main supply
- Improves spatial awareness, enhances dynamic contrast, and provides blacker backgrounds
- Has universal voltage compatibility (100-240V)
Product Considerations
- The standard DC block is not suitable for amplifiers with high power output—over 300 watts total
- The included cables are of cheap quality
- The DC Block 6 has a substantial size—444mm width
- The DC Block 6 might not allow the use of existing power cords due to the connector type
Takeaway: The Audiolab DC products are effective in removing DC humming problems. If there is a noticeable hum from an amp, the DC products are recommended to help improve sound quality.
