This is a 1m pair of RCA to RCA Phono cables. It is in excellent condition and comes in original box. The retail price was $699.

Synergistic Research’s Foundation Interconnects and Speaker Cables are the brainchildren of Lead Designer Ted Denney who wanted an affordable IC and SC loom with the performance for which other companies charge much more. To make this a reality, Ted distilled his highest performance cable technologies like pure six nines silver in a handmade Air String geometry with UEF Matrix Shielding taken directly from the Atmosphere X Series cables and a full Blue Fuse treatment to make these cables punch far above their weight class. When paired with our UEF Blue or Black AC Power Cords, you have an affordable loom with sonic performance enough for even six-figure stereo systems. Standard finish is black, also available in white on special order.


Jonathan Valin of The Absolut Sound concluded (TAS Issue April 2020):
"...I could happily live with the Foundations, which give you approximately 35-40% of what the Crystal Cables Ultimate Dreams offer, for sixty-five-times less dough! If that isn’t a bargain, I don’t know what is. One of the highest-fidelity budget wires I’ve heard, Foundation obviously comes enthusiastically recommended..."

Rick Becker of Enjoy The Music wrote (January 2020):
"...Synergistic Research is clearly on the cutting edge with their flagship Galileo line and new SRX power cable. The new Foundation Series cables are ample evidence of trickle down technology designed to capture new customers at price points where a lot of audiophiles call home. Dressing my gear with a complete loom from sources to speakers produced a consistency of sound among the different sources and easily revealed the differences when other components were swapped into the rig. I was skeptical that the Foundation cables would make such an improvement in my system, yet they have replaced cables that cost far more and taken my music far higher. Combined with a handful of their fabulous Orange Fuses, a $2000 to $3000 investment toward Synergistic Research’s Foundation cables has taken my mid-five-figure rig well into six-figure territory. That’s real value and an admirable feat!" CLICK HERE to read the entire review

The Absolute Sound’s Buyer Guide 2020 - 50 Greatest Bargains in High-End Audio:
"...Jonathan Valin wasn’t expecting much- and certainly not this much-from Synergistic Research’s immensely pliable, bargain-basement Foundation Series interconnects and cables, which are far slimmer, lighter, and less sophisticated in design than their rich relatives, the superb Galileo SXes. But, trust him, sonically the Foundations come way closer than shouting distance to the Galileos. Indeed, these two SR lines have a great deal in common-rich vibrant tone color, robust dynamics, spacious staging, lifelike imaging, high resolution. Oh, the more sophisticated Galileos are less bottom-up in balance, more finely detailed, and harder-hitting than foundation: then again, they ought to be-the cost ten-to-twenty times the dough. Put plainly, the Foundation Series is the best budget-priced wire Jonathan Valin has heard-and one of his references..."

"...a component level upgrade over much more expensive interconnects named for Norse gods. Quiet, fast, dynamic, holographic, tonally dense, transparent, detailed, and finely textured. An incredible bargain..."

"...the SR Foundation cables are terrific, thoroughly trouncing Nordost interconnects (at 3x the price) and the Heimdall 1 speaker cables and bi-wire links (at about 1.5x the price).This pretty much completes my transition from an all Nordost loom to all SR. I’m a happy boy..."

" far I have been listening only to the ICs, comparing them to my $1,500 retail Nordost Frey 2s. The Foundation ICs totally smoke the Frey 2s across the board and you’re not getting them back from me..."
