Advantages of REDpurl™ adaptive audio cable geometry 

 

 

Conventional cable construction methods with their symmetrical geometries create repeating patterns of interference between fixed, closely bonded wires. Our unique REDpurl adaptive asymmetric geometry was developed to overcome this by allowing variations in wire spacing and alignment creating an asymmetric geometry with the following advantages:

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

To deliver a full range of dynamics and weight across the frequency spectrum, an audio cable requires different diameter conductors. Smaller gauge wire can deliver excellent detail and dynamics in the upper frequencies, but their accompanying lack of bass leads to a shift in the tonal balance. To eliminate this problem, the conductors in our Experience cables are of several carefully chosen diameters. Our unique geometry allows us to combine these different conductors without losing the natural flow and musicality of recorded music that can occur in conventional cable designs.    

Tuning 

The notion that all you need is the 'perfect' cable to successfully connect a myriad of different audio equipment designs seems fanciful. How can the physics in a single cable, however well designed, always match the requirements of different components?   

 

 

But there will be a 'best' interconnect that matches the requirements of audio equipment chosen by a HiFi enthusiast, and by allowing us to bend the physics in our cables we can more easily achieve this goal.

Choosing the right conductors

 

 

 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.

Dielectric

 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 dielectrics 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, preferring to rely on our REDpurl™ geometry to keep RFI at bay.  

Our Experience680 RCA interconnects only are directional. 

Termination

Our RCA interconnects can now be terminated using WBT-0114 phono plug with clamping sleeve or the push-on KLE copper harmony termination.

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.

 

 

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

 

 

Tuning is simple and can be explored using only a handful of configurations as shown below but we can also ultra-tune our cables for you in our workshop: More about tuning
