Advantages of a tunable hifi audio cable design using REDpurlGeometry

 

 "REDpurl Adaptive Geometry from the very start was always about combining the highest levels of detail and dynamics with musicality but that it was also able to tune to better match audio components far exceeded our expectations." Chris Bell, Designer. 

 

  Wire on Wire’s unique REDpurl™ tunable audio cable geometry uses a triple gauge construction providing a full range of dynamics

 

Different gauge conductors provide a full range of dynamics and tonal colour across the music spectrum.

Once braided, our triple gauge construction creates space between conductors resulting in a specific geometry.

 

Asymmetric, intersecting, non-parallel conductors provide unique benefits with our tunable audio cables, interconnects and speaker cables

 

There are certain benefits to this arrangement.

 

Tunable audio cable geometry reduces crosstalk, capacitance, harmonic modes and allows fine-tuning between hifi components

 

Tuning 

You can't have a 'perfect' cable. The physics in a single cable, however well designed, will sound different depending on who is listening to it and the equipment it is plugged into. 

REDpurl Geometry allows the user to alter the physics in a cable by tuning the relationship between conductors allowing its electrical properties to be optimized

 

Tunable audio cables, interconnects and speaker cables allow a cable’s physics to be modified to suit a hifi system

 

 Each loop within a tunable cable produces a specific change to the hifi audio presentation

 

Spacers alter the geometry of our cables altering their capacitance and tuning their musical presentation.

 

Wire on Wire's audio interconnects and speaker cables are tuned using spacers to alter the loop width

 

Tuning our audio cables is simple and can be explored at home using only a handful of configurations (our speaker cables can also be tuned) and we can also Ultra-Tune our interconnects and speaker cables for you in our workshop.

 

Summary of REDpurl™ properties

 

REDpurl™ tunable geometry is flexible enough to allow tuning whilst retaining a stable core structure

 

Wire on Wire's tunable cables, interconnects and speaker cables have a stable core geometry

   

Intersect not parallel

Conductors intersect at angles, rather than lying parallel with each other so reducing interference or crosstalk.

Low capacitance

The result is more space between conductors creating a low-capacitance cable with good mechanical flexibility, without the need for fillers or sheaths.

Phase differences

REDpurl™ geometry gives smaller-diameter conducting filaments a longer length-per unit-distance than the larger diameter wires. This addresses possible phase differences.

Harmonic modes

The organic asymmetric structure of the REDpurl™ geometry prevents identical relationships between conductors becoming established so inhibiting harmonic modes across the music spectrum and improving dynamic control.

Conductor diameter

We believe in order to deliver a full range of dynamics, weight and tonal colour across the frequency spectrum, an audio cable requires different diameter conductors. However, when combined using conventional techniques, their proximity to each other can effect the natural flow and musicality of the sound. We find the extra space we create between wires sounds a lot better.

 

HiFi audio cables-choosing the right conductors

 

The Experience range of tunable audio cables use the best wire conductors and insulation

 

 Multi-stranded

For us, multiple strands of silver-plated copper convey the timbre of instruments and voice more realistically than single conductors.

Silver-plated copper

When silver-plated copper is used with the correct cable geometry, it produces a sense of delicate clarity that is unmatched by any form of pure copper or pure silver that we have tried.

Insulation

 PTFE is a very stable, high-performing insulator with a low dielectric constant. It provides excellent mechanical properties and a consistent level of detail and clarity above other insulators that we have tested.

Shielding and directionality

We have carried out extensive tests on cable shielding. Whether floating or grounded it always adds a slight artificiality to the sound, removing some of the natural exuberance of the instruments so we don’t use shielding.

Our Experience680 RCA interconnects are directional even without tuning. Once tuned all our cables are directional. 

Termination

Our RCA interconnects are terminated using the push-on KLE copper harmony termination, which we have found are well designed and produce the highest levels of musical reproduction.

Burn-in

A cable sounds more balanced musically for a burn-in over the course of a week. It is, therefore, best to listen to the cable during this period to appreciate what it delivers before tuning it, but there is no reason to extend a burn-in period each time the wire positions are varied.
