We are continuing the story of AIR technology with the new REFERENCE MICRO AIR series: As with the already legendary AIR Helix cables, air is a central component of the insulation concept in the new REFERENCE MICRO AIR technology. However, due to the low loudspeaker impedances low line resistances and low inductance are also very important for loudspeaker cables. For this reason, a total of 6 concentric copper conductors are used in the REFERENCE LS-204 XL MICRO AIR in addition to the air dielectric. Thanks to this multicore architecture, the magnetic fields of the positive and negative conductors overlap and neutralise each other.
This reduces the inductance of the cable considerably, thereby guaranteeing unadulterated transmission of the audio signal over a broad frequency range. The LS-204 XL follows this approach and has a well-balanced sound character with precise timing with a well-controlled foundation. This cable is therefore primarily designed for fully-sized floor-standing loudspeakers. Of course, sound always is evaluated subjectively and ultimately depends on the overall constellation of the hi-fi system. In the end the decisive factor is your very personal auditory impression.
MICRO AIR TECHNOLOGY
The laws of nature cannot be switched off. They need to be used skilfully. Every cable has so-called parasitic effects due to these laws of nature. Among other things, this includes the capacitance – i.e. the fact that a cable, like a battery, stores energy temporarily and releases it again with a delay. This effect strongly influences the transmission of audio signals and is undesirable. Cable capacitance is a physical phenomenon and its size depends on various factors. One essential factor is the insulation material, the so-called dielectric, which can increase the capacity many times over. Air on the other hand does not do this and is therefore the ideal insulator. Part of the insulation of the MICRO AIR technology is its complex, diamond-shaped structure. The chambers created by this design increase the distance between the conductors and increase the air content in the insulation. In this way, irritating capacities are reduced and the transmission characteristics for the sensitive audio signals are optimised.
By contrast to conventional conductor structures, in which the arrangement of the individual wires in a cable is chaotic, the wires in the concentric copper wires are arranged in accordance with an exactly defined scheme in which they are precisely ordered in several layers. This design reduces irregular contact points between the wires, which harmonises the signal flow and minimises transit time differences. Impulses can be played back exactly while retaining the spatial information of the music. A thin layer of polyethylene protects the highly pure copper from oxygen and therefore against oxidation.
A loudspeaker cable must transport energy and information in equal measure. Loudspeakers can also be moody little beasts, with a very dynamic electrical life of their own. They behave differently for every tone and volume and have to be constantly kept in check by the amplifier. This means the signal on a loudspeaker cable is a jumble of tiny to huge levels, alternating current and voltage of different frequencies and phase lengths. To faithfully transmit the extremely fine details that define sound and space and lend emotion to the music, the cable has to metaphorically keep the speaker on as tight a leash as possible to the amplifier. These beasts can be tamed by applying physical laws, using the right materials, and an appropriate cable architecture.
The REFERENCE LS-204 XL MICRO AIR is available with BFA Bananas or with cable lugs or as Easy- Plug version. The surfaces of the BFA Bananas and the cable lugs are finished with a rhodium coating and are therefore extremely durable. The contact surfaces and the screw connection of the cable lugs are manufactured from a single piece, thereby avoiding contact resistance. The contact surface, which has slits on the side, changes to a concave shape when the device terminal connections are tightened, thus preventing the cable lugs from sliding out.
OUR CABLE MANUFACTURE
Just like our AIR HELIX cables, the REFERENCE MICRO AIR cable technology is manufactured in our own factory in Germany. In addition to the complex manual assembly of the cables, we have paid strict attention to corresponding quality control. After production each cable is put through its paces. Functional tests as well as mechanical tests are performed and of course we also monitor live performance as part of product development for the greatest possible precision and low-loss signal transmission.

If you have any questions about this policy, please contact us at firstname.lastname@example.org or 02 9427 6755
We require a receipt or proof of purchase.
- Please do not send your purchase back to the original manufacturer.
- There are certain situations where only partial refunds are granted (if applicable). For example:
- Any item not in its original condition, is damaged or missing parts for reasons not due to our error

Goods Damaged in Transit.
If any goods arrive damaged, please contact us as soon as possible. Len Wallis Audio will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund the price to you. Damaged goods must be returned in the condition received by you with all original packaging, accessories and/or manuals.
Refunds will be normally be processed within five (5) days.
Where Len Wallis Audio considers the goods to have breached a consumer guarantee, any shipping costs to return the goods to Len Wallis Audio will be at our cost.
Returns and Repairs.
You may visit Len Wallis Audio and a staff member will assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be repaired, or providing you with a replacement.
Goods must be returned within a reasonable time.
If any goods cannot be easily returned to us due to their size, the fault or because they have been affixed or installed in your premises, please contact us and we will arrange an inspection to assess the goods.
Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be provided with an indicative repair time, which time may vary due to reasons beyond ours or the repairer’s reasonable control, such as part availability and incorrect fault description.
You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident, or where your rights under the Australian Consumer Law or any manufacturer’s warranty do not apply. We may provide you with an indicative fee, which may vary due to reasons beyond our control.
If any goods that you return are capable of retaining user generated data such as files stored on a hard drive, and songs stored on a portable media player, the replacement or repair of the goods may result in loss of the data. In these circumstances, we recommend you back up data to prevent data loss, and remove sensitive or confidential data, as a party assessing and/or repairing your goods may be required to view data in the course of carrying out the assessment. We will not be responsible for any data loss.
In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
Where you have any questions or concerns relating to your Order, please immediately contact us
We understand that sometimes you may simply change your mind about a purchase or have made a wrong selection. In these situations, you have 14 days in which to return your item for a refund, exchange or store credit. If more than 14 days has passed since your purchase we can’t offer you a refund, exchange or store credit.
To be eligible for a return, refund or store credit your item must be in the same condition that you received it. Which is to say, it must be in the original unopened packaging, and in ‘brand new’ saleable condition.
Please note that current Australian Consumer Law does not require us to offer a ‘Change of Mind’ refund. Rather Len Wallis Audio offers 14 day ‘Change of Mind Policy’ in good faith.
