Synergistic Research HD SX Ground Cables

By cleaning up your system’s ground connection you hear a noticeable improvement in soundstage height, depth and width thanks to a lower noise floor. Soundstage scale is improved with richer tonal density especially at the edges of your sound field. Image outlines are brought into clearer focus while musicality and overall system refinement are greatly improved.

Even more so with the new HD SX (High Definition) Ground Cables!

Since engineering the original HD Ground Cables almost 10 years ago, SR's understanding of building the world’s best-sounding cables has advanced exponentially. In areas such as metallurgy, UEF compounds, and high voltage and high current conditioning processes have collectively gone well beyond anything we could have imagined in 2015. So it was time SR applied all they’ve learned to build the next generation HD Ground Cable. They started with the same hand-made AirString Geometry. SR added a new single crystal pure six-nines silver conductor in an air dielectric for cleaner highs and a noticeable increase in resolution combined with a more relaxed presentation. SR then add a new UEF Compound to a new Matrix Shield for an even lower noise floor in a more holographic soundscape. SR then added the brand new Three Stage High Voltage conditioning process initially developed for the flagship SRX cables for a dramatic lowering of the noise floor. All told, these improvements create a whole new level of performance, resolution, and musicality. In short, adding the new HDSX Ground Cables to your system with any of SR's Ground Block technologies will improve all aspects of sound, and not in a subtle way. Try risk-free in your system and rediscover the art of being well-grounded.

Mike Girardi, The StereoTimes, Dec.2015:
"...I wouldn’t hesitate to recommend the High Definition Grounding cables.  The expense is justified by that delivered performance. The addition of the SR GB and HDG cables exceed my expectations and was similar to the level of improvement the SR Powercell 10 SE MKII I reviewed back in 2013 brought to my system.  The more I listened to my system with the HDG cables and Grounding Block, the more I was convinced that the addition of these products are on the critical path in assembling a truly high performance audio system..."

Dr. David W. Robinson, Editor-in-Chief, PFO, November 2015:
"...this component provides a common grounding point for a system, via grounding cables that connect to the central block via pins. The effect on our system was immediately obvious:  A thin layer of hash that had been below my notice (Ain't it always the way?) was removed, clarifying a system that I already thought was exceptional. And this is the constant challenge of fine audio...you learn about the presence of "layers" in playback by subtraction. As Joni Mitchell sang in her song, "Big Yellow Taxi," "You don't know what you got ‘til it's gone." Well, yeah. And that's how it is with noise floors and transparency in audio. Certainly the Grounding Block knocked down some haze, no doubt about it..."

Steven Plaskin, AudioStream.com, May 2015:
 "...transient quickness and impact of the bass was greatly improved with the Grounding Block"
 
"...louder musical passages were definitely clearer with better resolution of transient detail using the Grounding Block..."
 
"...the Grounding Block not only increased the soundstage, but enhanced the clarity of Krall’s voice. The enhancement in focus and definition of her voice was significant..."

"...for those that have the financial resources to add the High Definition Ground Cables to the Grounding Block, the money will be well spent given the level of improvement provided by the combination of these innovative products..."

"...when I decided to write about the Synergistic Research Ground Block and High Definition Ground Cables, I thought that this would be a short review of products that delivered subtle improvement to the sound of my system. I was not prepared for the major sonic enhancement that these products delivered. The extent of the positive enhancements goes far beyond merely those of a system tweak!"
