GutWire Cables have recently upgraded their first level of interconnects and speaker cables. The principal change is a replacement of the insulation from polyethylene to Teflon, known for its superior effect on sound. A slightly purer copper used for the conductors adds further sonic benefits. The uplift in sound quality is significant and the models are now called Synchrony Cube and Congruence Cube.

Whilst recognisable still as the Synchrony or Congruence sound, there is an audible gain from these previous popular models, in increased transparency and improved holography. These are very much part of the GutWire Cables characteristics, but the Cube Series takes these to a higher level. An extremely linear and wide bandwidth with no emphasis to any particular frequencies. The renowned natural tonal balance is further enhanced with 100% Mylar shielding and damping using their unique natural minerals. Dynamics and rhythmic speed portrayed realistically but without exaggeration.

GutWire cables are known for creating wide and deep sound pictures. These upgrades take this Cube Series models to a higher sound level at realistic prices, offering more attractive options to an already impressive range of interconnects and speaker cables.

Alan Sircom has reviewed the Synchrony Cube cables in HiFi + Issue 207 May 2022.

"They just tell you what your music and your system can sound like with a surprisingly large sonic impediment removed.... Honesty without the courtroom drama. What more do you need?
