Experience660-S speaker cable with tunable geometry


The Experience660-S is a meticulously  handcrafted speaker cable using our unique REDpurl™ Adaptive Geometry employing a true flat-braided construction.

From the start it was capable of such exceptional levels of audio reproduction we haven't seen the need to make any significant changes to its design since.

Its open tunable design means it remains a 'live' configurable hifi component, which can be optimized without the need to launch innumerable new models.

"...Experience660-S would seem to be in the upper tier of performance even before you take the tuning into account." Reviewed by Paul Messenger, HIFi+, January 2020.


" was a real pleasure to evaluate a cable that actually did what it said on the tin it would do. That the increase in image definition and depth was claimed and executed is a real milestone in a reviewer’s experience of cables and makes worrying about "synergy" almost redundant." Review by Dominic Marsh, Hifi Pig, March 2018.


Stuart Dunn of 3SquareAudio uses the Experience660s cable for product development of their speakers. "It creates more silence and blackness; it’s what it’s removing that I like, so I can focus more on what’s left, listening with greater ease to the music."  


Technical overview



  • Unique, hand-built, tunable REDpurl™ Adaptive Geometry.
  • Combining the highest levels of detail and dynamics with musicality.
  • PTFE-insulated, silver-plated copper conductors.
  • Asymmetric, intersecting, non-parallel conductors address challenges of crosstalk, capacitance and harmonic modes. 
  • Three different conductor gauges fully reproduce tonal and dynamic colour across the music spectrum.
  • Larger conductors compared to our RCA interconnects.
  • Tuning, using spacers at individual cable loops, allows matching of audio components creating the music that connects with you.
