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.

We engineered Foundation SX speaker cables to include core Synergistic Research technologies in the purest expression possible. We intended to make a complete loom of cables affordable for audiophiles who otherwise might not take that plunge. The loom effect acts as a performance multiplier within the Foundation SX line to deliver soundstaging, low noise floor, dynamics, and musicality beyond Foundation's individual price points.
Foundation SX speaker cables start with Air String geometries comprised of pure silver mono-filament conductors in an air dielectric hand-made in our California factory for high levels of detail and natural soundstaging combined with parallel heavy gauge copper matrix conductors, so you experience low frequencies with extension and control. We then apply a UEF Compound first developed for our flagship SRX cable loom for a lower noise floor than was possible with the original Foundation Series for enhanced detail with enhanced musicality. We then apply the same Long Duration High Voltage Conditioning Process that enables SRX cables to lead the industry with realistic sound stage scale plus resolution and musicality in equal measure. Lastly, we included newly developed UEF Carbon Tuning Discs so you can custom voice Foundation SX speaker cables to your system or run them straight. The choice is yours.

Based on our patented UEF technology, each disc gets treated with a unique UEF compound that interacts with EM fields wherever you place them in your system or on cables to improve sound quality. The conductive carbon fiber material of the disc enhances the interaction between the UEF compound and the surrounding EM fields where it is placed. The Gold- Carbon Tuning Discs flesh out rich harmonics combined with a clarifying effect in the sound field for a more lifelike and holograph...

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:

  • Synergistic Research products often include proprietary EM (Electromagnetic) cell technology to actively filter and condition AC power, without limiting current flow.
  • They provide a range of tuning options, such as selectable ULF (Ultra Low Frequency) generators and included tuning discs, to tailor the sound to specific music genres or system preferences.
  • SR power conditioners commonly feature isolated outlet banks designed to separate analog and digital components, reducing cross-contamination and improving overall clarity.
  • Synergistic Research bundles their power conditioners with high-quality power cords and upgraded wall outlets, offering a complete power conditioning solution out of the box.

SR30 AC

  • Positioning: The entry-level power cable in the Synergistic Research lineup.
  • Description: Offers a balance of performance and affordability, featuring 12-gauge OFC copper for high current delivery. It includes UEF Matrix Shielding, similar to higher-end models like the Atmosphere SX, to reduce noise and enhance resolution.

Atmosphere SX Euphoria SX Level 3

  • Positioning: A mid-tier power cable in the Atmosphere SX series.
  • Description: Uses Active Shielding and Swiss-made power supply, offering a sound profile akin to the premium Galileo SX. It combines copper and silver conductors.

Galileo Discovery Power Cables

  • Positioning: A high-end power cable series within the Synergistic Research lineup.
  • Description: Features an Active EM Cell and UEF Matrix Shielding for noise reduction.

SRX AC

  • Positioning: A premium power cable positioned just below the flagship SRX XL in the lineup.
  • Description: Made with pure six-nines silver conductors and advanced UEF shielding.

SRX XL AC

  • Positioning: The flagship power cable in the Synergistic Research lineup.
  • Description: Features additional pure silver geometries and advanced tuning modules.

Our take on the brand

Synergistic Research stands out for their Active Shielding technology, which applies DC voltage bias to cable shielding to reduce noise, and their dual ULF generator system in products like the PowerCell 8 SX that enables switching between different sonic signatures. Their product line includes distinctive electromagnetic cell-based power conditioners and the Tranquility Pod, which uses active EM cells and Graphene to condition the electromagnetic environment within audio components.
