Au24 SX
Analog and Digital Audio Cables

Au24 SX audio cables represent the biggest transformation in cable performance ever achieved by Audience. ALL of the SX cables are notably more transparent, dynamic, more resolved and have greater weight and authority, immediately noticeable. Everyone who has tried them thus far has been very impressed with the advancements we have achieved through the use of purer OCC copper (now six nines) and higher quality XLPE dielectric insulation as well as tweaking of geometry as compared to the historic lines of Au24 cables. Audience double cryogenically treats all SX cables in our in-house cryo lab. Each component part of the cable is individually treated, then, after the cables are assembled and tested, we cryo the completed cable. This is process is called CRYO².

Au24 SX are offered in RCA, XLR, S/PDIF, AES/EBU, phono and all configurations of loudspeaker cables. Note that the Au24 SX speaker cables are a heavier gauge than the previous Au24 SE. In comparison to the SE, the SX speaker cables are more relaxed yet more dynamic and have a richer tonal palette. The RCA connectors are a new proprietary solder-free design. And the XLR is a whole new true dedicated differential cable designed from the ground up solely for balanced circuits.

Au24 SX cables, like all previous Au24 cables, are low mass and low eddy current resistance designs with minimal jacketing materials. They retain natural timing and timbre thus recreating original sound fields like no other cables.

Cables FAQ

How Important are Cables in a System?

Audio cables are often referred to as accessories. However, an audio system cannot make sound without cables installed which implies that they are essential components. And much like the other components in the system, cables must be chosen with the same research that one would perform in choosing an amplifier, a speaker or a turntable. Characteristics such as coloration, distortion and other anomalies must be minimized in order for the system to perform at its optimum. Too often, audiophiles and music lovers treat these essential components as after thoughts and end up compromising the performance of their carefully chosen audio gear.

How do I know if Audience cables will work well in my system?

Audience audio cables are widely known and awarded for being natural and non-colored, maintaining a high degree of faithfulness to true musical characteristics in every way. Because of this natural musical window afforded by Audience cables, they are the most widely applicable cables. Quoting from reviewer Doug Blackburn, in his 2003 review in SoundStage.com "The Audience Au24 interconnects and speaker cables are commendably neutral and natural, and they help you forget about chasing the pot o’ gold at the end of the audiophile rainbow".

What are "e" enhanced and "SE" cables?

Proprietary technologies to improve performance of Audience cables has been developed over the years. The "e" enhanced upgrade was introduced in November of 2007 and "SE" special edition as of January of 2013. Generally speaking, these upgrade technologies simply remove veils, thus allowing you to be ever closer to the musical truth. The opportunity to upgrade existing Audience cables is described under the Product Upgrades section.

Why are Audience cables so thin?

Simply put, audio signal is most accurately delivered by conductors of lower mass. Unfortunately, many water hose size cables are marketed today under the "bigger is better" banner and nothing could be further from the truth. To illustrate the detrimental effects of heavy gauge audio cables, Audience has made a short video demonstration of the very pertinent science of an invisible, yet very powerful force, known as eddy current resistance. The written explanation, with references, is also on this website: eddy current.

Is it better to use single wire or bi-wire speaker cables?

This is a very controversial question. Generally speaking, Audience asserts that simpler is almost always better. In the case of single vs. bi-wire speaker cables, we believe that one signal path from the amplifier to speakers is better than two. In many cases we have provided customers with both single speaker wires and bi-wire to make their own comparisons. Almost invariably, those customers found that the single wire approach, in conjunction with equal quality jumpers, was best. Some reoccurring exceptions were specifically from users of Vanderstein and Von Schweikert loudspeakers.

For bi-wired speakers what is the best approach to using jumpers?

On bi-wired loudspeakers, it is important to use a jumper of equal quality as the primary speaker cables, because the characteristic sound of jumpers tends to be imparted back into the full sound spectrum.

Is stranded or solid core wire best for audio cables?

Stranded wire is flexible whereas solid core is not and will tear when flexed. Some people make the point that these tears heal; however, where healing takes place there are still new crystal boundaries formed as scarring build up.

Small diameter strands do not have the same frequency limitation as larger solid core due to skin effect, which reduces the effective diameter and increases the effective resistance of the wire at high frequency. Therefore, typically, small stranded wire has better sonic attributes at the higher frequencies.

Thin wire has lower eddy current resistance, therefore it is more coherent compared to thicker wire, much like the effect of inductance. Think of a magnetic field being introduced into a flat conductive surface. When the magnetic field is in motion, like an audio signal moving through conductive wire, it produces an electrical current in the conductive surface, which in turn produces a counter magnetic field that impedes the motion of the originating magnetic field. If the surface is broken up in smaller pieces, the magnetic field has only a small conductive path and therefore the eddy current resistance is greatly reduced. Skin effect/eddy currents are going to occur either way; however, at smaller diameters they occur at higher frequencies therefore have less affect in the audible band.

Audience Audio Cables

Audio cables are often referred to as accessories. However, an audio system cannot make sound without cables installed which implies that they are essential components. And much like the other components in the system, cables must be chosen with the same research that one would perform in choosing an amplifier, a speaker or a turntable. Characteristics such as coloration, distortion and other anomalies must be minimized in order for the system to perform at its optimum. Too often, audiophiles and music lovers treat these essential components as after thoughts and end up compromising the performance of their carefully chosen audio gear.

The idea of cables as components is a controversial subject. There are many who think that "wire is wire" and don't accept that cables can either optimize or compromise the performance of an audio system. Traditional tests for difference in cable reveal very little if any electrical differences between brands. However, the human ear/brain is a far more sensitive and discriminating test apparatus and deciphers differences in cable brands rather easily. This ability can be developed much like wine tasting. As you become more experienced, differences, shadings and nuance become more readily noticeable.

Audience cable products are the end result of years of research into what matters most in an audio system...true fidelity to the signal without artificial embellishments or unwarranted voicing. Audience cables are not off the shelf items that have been adapted for use in an audio system, they are products that have been designed to actually preserve the audio signal in the least damaging fashion possible. "Neutral" or "natural" are the terms we hear most often when end users describe their performance.

Audience Au24 SX cables are made of 99.9999 pure OCC copper in very high quality XLPE (cross linked polyethylene) dielectric and insulation.  Both the single ended (RCA) and loudspeaker cables are a very unique and innovative design. The geometry is a dual concentric coax, perfect lay ribbon wind with opposing angles of the two conductors.

Audience calls this innovative approach “Perfect Lay Geometry”. Though a flat, non braided, coax design is very difficult to manufacture, Audience adheres to this design for several reasons. The benefits include a more linear signal transfer, improved timing and reduction of group delay artifacts. Second, the angle relation between the two conductors tends to balance the electromagnetic fields surrounding the cable to further improve the sound quality by rejecting noise without relying on shielding, which damps dynamic flow. Audience has painstakingly experimented with these variables to optimize for the very best sonic result.

Low mass/low eddy current design is integral to Au24 SX cables. In a 2010 report, MIT concluded that audio signal is ballistic in nature. Much like a bullet traveling down the barrel of a gun, it is imperative that the barrel and the bullet be properly sized in relation to each other. If the barrel is too large, the bullet will wobble and cannot be controlled. MIT concluded that smaller conductors increase the probability of the signal transport being ballistic in nature due to the reduction in electron scatter. Correspondingly, MIT concluded that the purity of the conductor also significantly impacts electron scattering or the reduction thereof. The reduction of electron scatter works to improve accuracy of group delay, phase and timing issues. The more the signal is ballistic in nature, the less the signal interacts with the conductor, making the cable virtually invisible to the audio signal.

Whereas many manufactures of audio cables took the marketing path of bigger is better, Audience found this approach, like MIT’s findings, to be counterproductive towards optimal sound reproduction. This philosophy is represented in the ultra low mass connectors and wire gauge of all Audience cables. Audience has also long asserted the negative effects of eddy currents in audio cables. Here again, the size of the conductor directly relates to the strength of eddy current resistance. Eddy currents are an opposing, or resistive, magnetic field created from the passing of a primary magnetic field, from the audio signal, through a conductor. This phenomenon is easily demonstrated by dropping a magnet through a non-ferrous copper tube where you can witness the significantly impeded movement of the dropping magnet. By dropping the same magnet through a copper tube of greater mass, the impeded movement is increased; i.e. the magnet moves slower as it passes through greater mass. The following Youtube video is a graphic illustration of this principal.

The proof is in the listening. Over the past twenty years, Audience cable designs have received numerous awards and accolades from all corners of the globe. Audience audio cables are known for providing extreme levels of transparency, low coloration, high resolution, and retaining musicality and warmth, a balancing act that is difficult to achieve. Most importantly, Audience has a 20 year following of customers who are satisfied music lovers, which is the ultimate goal.
