Synergistic Research
PowerCell 8 SX
Huge Feb. 2026 promotion!

The Pulse of Pure Power
Non-current limiting. No compromises. Just your music, free from noise.

The Synergistic Research PowerCell 8 SX reimagines power conditioning by incorporating every available technology from their portfolio into a compact, ultra-performance unit. Engineered from a clean slate, it brings together an array of advanced features within a sleek, solid chassis crafted from machined aircraft aluminum and carbon fiber to control resonance; it’s form dictated by its role as one of the world’s highest-performance non-current limiting line conditioners. SR doesn’t compete with others, only with themselves. Their relentless pursuit of perfection will never end.

The PowerCell 8 SX introduces significant advancements, including a reformulated Ultra Low-Frequency RF bias and the same power supply technology found in the latest Galileo SX PowerCell line conditioner, engineered to ensure the cleanest power delivery and the lowest possible noise floor for your audio system. With the addition of a redesigned Ground Plane Technology, the PowerCell 8 SX achieves one of the blackest backgrounds of any PowerCell to date, allowing the essence of your music to come through.

A highlight of the PowerCell 8 SX is its comprehensive redesign of the patented electromagnetic cell, which, in turn, was taken directly from work on the flagship 20-outlet SRX power conditioner, which retails for over €70.000. The PowerCell 8 SX gets the first major EM Cell redesign in over a decade, where the patented Electromagnetic Cell is enhanced to have twice the surface area for greater conditioning power compared to previous folded EM Cells. This upgrade is complemented by significant improvements in the internal materials and assembly processes, setting the standard for efficiency and performance.

The PowerCell 8 SX stands out as a testament to the commitment of SR to pushing the boundaries of performance, packing their latest technology into a compact form factor, and is ideal for audiophiles seeking the best possible power conditioner without compromising space or design.

 

Galileo and SRX Technologies
What’s Inside

The PowerCell 8 SX exemplifies Synergistic Research’s approach of cascading innovations from flagship models down to more accessibly priced products, ensuring cutting-edge technology reaches a wider audience. It incorporates the sophisticated EM Cell power supply from the esteemed Galileo SX PowerCell, and leverages the advancements in Electromagnetic cell design from the SRX PowerCell. This approach ensures that the PowerCell 8 SX delivers exceptional performance and value, making premium technologies available at a competitive price point.

 

Galileo SX Dual Frequency ULF Generator

The PowerCell 8 SX now utilizes a multi-frequency ULF Schumann Frequency Generator to complement both large and smaller-scale performances. To make accurate small and large scale soundstaging reality, SR uses technology first developed for their Atmosphere Acoustic Field Generators. Ultimately, the two new frequency combinations were engineered to perfectly complement large and small scale acoustic environments after first creating multiple combinations that proved unncecessary in the final stages of development. The multi frequency bias of the internal EM Cell is similar to what you hear when comparing the original FEQ field generator to an Atmosphere Acoustic Field Generator, which presents music on a grander scale with improved dynamics and musicality. To optimize the Galileo PowerCell SX to your system and personal tastes, press a button to switch between Red and Blue settings selecting the option that makes music in your stereo when playing your favority recordings.

 

Two frequency bias, one perfect sound

Blue Frequency: voiced for acoustic instruments, vocals, and smaller-scale performances.
Red Frequency: convincingly portrays large-scale performances and electronic music.

Synergistic Research PowerCell 8 SX & SRX XL AC door Marcin Olszewski and Jacek Pazio @ soundrebels.com
Mening 1: “Om niet te muggenziften, geef ik tot slot toe dat het moeilijk is om een ​​aspect te vinden, misschien afgezien van het financiële aspect, dat niet alleen zou kunnen verslechteren, maar ook zou kunnen verbeteren na gebruik van de Synergistic Research PowerCell 8 SX in vrijwel elk systeem. En als je naast de conditioner (het woord “filter” dekt de complexiteit en verfijning van de PC 8 SX zelf, noch het gunstige effect ervan op het geluid van de aangesloten apparaten, volledig niet) ook de SRX XL AC-kabel aanschaft, ben je helemaal tevreden.”
Mening 2: “Naar mijn mening kan ik hem zonder enig bezwaar aan iedereen aanbevelen, want het geluid van de Synergistic Research Power Cell 8 SX is zo evenwichtig qua gewicht en helderheid dat zelfs systemen met een uitzonderlijk goede geluidskwaliteit moeite zullen hebben om het volledige potentieel van dit Amerikaanse ontwerp te benutten. Ondanks zijn kleine formaat presteerde hij bij mij erg goed, zelfs met de aanzienlijk grotere elektronica. Dus als je overweegt een stroomfilter voor je geliefde audiosysteem aan te schaffen, moet je deze zeker overwegen. Het is het absoluut waard.”

Synergystic Research Powercell 8 SX  “The Best Under $5k?”  by Anton @ hifichicken.com
“We compared the new PowerCell 8 SX, the first PowerCell to come out of the SRX PowerCell development program, replete with the first fundamentally re-engineered electromagnetic cell – the heart of the powercell, in its 15-year history. After comparing it to the most expensive line conditioners from AudioQuest and Shunyata Research, I’ll just say, this is one of the best line conditioners on the planet regardless of price. I encourage all to compare the new PowerCell 8 SX to anything else on the market regardless of price.”

SR PowerCell 8 SX  “Pushing your sound system to the next level with innovative technology.”  by Rick Becker @ EnjoytheMusic.com
“The jump in technology and the accompanying improvement in sound quality have catapulted my system into Best Rooms territory at a price that would embarrass many manufacturers.”

 

 

 

Synergistic Research Power Cell 8 SX  “Give your system a well-deserved boost!”  by John Bugailiskis @ BestOfHighend.com
“I noticed an immediate increase in detail and resolution, with individual instruments becoming more apparent. Vocals also gained clarity and the overall soundstage expanded. But most impressive was how the PowerCell 8 SX created the blackest/quietest background (reduction of the background noise floor) I have heard in a power conditioner, and did so without losing any details in the music.”
“For those seeking to unlock the full potential of their systems, the PowerCell 8 SX stands out as one of the best power conditioners on the market, especially given its price. It made such a dramatic difference in my listening tests that I have added one to our reference system.”
