What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
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.

DC Block 6

/
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.
