AR Sound Lunar Interconnect Cable 4-Pin DIN 1.0m

Here we have a high quality Lunar interconnect cable from AR Sound. Being fitted with 4-pin DIN connectors at both ends makes them a perfect alternative to Naims own cables and there are numerous testimonials on their website from satisfied Naim customers. Our example is in fully working condition and will be suitably packaged.

Features:
A Select aerospace grade cable with silvered copper alloy and extruded PTFE dielectric insulation.
Triple multi layered braided shielding with 99.5% coverage ensure full protection from RFI & EMI.
Pseudo balanced configuration – A floating double screen for extremely low noise floor and superb dynamics.
Anti vibration mechanism – An Anti-Resonant polymer treatment for the DIN plug for controlling vibrations conduction and damping plug resonances.
Following years of extensive listening tests to top quality cables used in the aerospace industries, The cable used to compose this exceptional interconnect, has been expertly selected in order to achieve the highest possible standards employed by the Lunar interconnect.
The Lunar interconnect contains four 21 AWG main copper alloy conductors.
The main conductor’s insulation is made of Teflon (PTFE) and fully screened in two layers:
* Two primary silver plated copper braids which protect the internal signal hot and return wires from RFI.
* A secondary 14 AWG Copper shield which is overlapped over the two internal screened cables (three braided screens in total). A special arrangement was done in order to lower the stray capacitance of the complex shielded cable.
Pseudo balanced configuration: The screens on the Lunar cable serve as a genuine shield which directs the picked up
noise to a single point, thus avoiding the noise build up over the return path conductor a usual occurrence in unbalanced Interconnects.
The Lunar employs two balanced cable construction, allowing the use of first main conductors for hot, and the second main conductors for return, while screen serves as a protective shield.
Triple RFI & EMI protection:
Two main conductors used in each internal cable, twisted to further enhance RF rejection of the cable.
An internal screen withholding RF noises from penetrating the twisted pairs cables.
A secondary screen withholding RF noises from penetrating the whole cable complex.
A 99.5% coverage which ensures full protection from RFI & EMI.
The main pair of twisted conductors in each of the internal cables constructing the Lunar, is made of a special, aerospace grade copper alloy carefully selected after extensive listening tests for its superb sonic qualities and durability. Unlike regular copper wires which tend to deteriorate to some degree after bending, the special alloy maintains its metal structure.
This unique copper alloy has a supreme resistance to oxidation, which ensures the cable’s longevity and long term performance quality. In addition, the copper alloy wire comprises a silver content which allows for better bonding to the WBT 4% silver solder used to make this superb interconnect.
The interconnect insulation is made of Teflon (PTFE). PTFE is the best insulation material used in the cables industry which has the lowest dielectric absorption.
Using Teflon (PTFE) as insulation is a prime consideration in Hi-End interconnects. Teflon maintains an extremely low capacitance and high resistance between the internal leads respectively, which keeps the interaction between channels to a minimum.
The low dielectric absorption of Teflon allows locating the main conductors in the Lunar cable in a very tight configuration which renders the Lunar a very high bandwidth cable while maintaining a low capacitance. Yet another benefit is that Teflon also bonds very tightly to the metal conductors and prevents the oxidation of the metal over the years. It is only the high cost of Teflon (PTFE) cables which leads manufactures to choose inferior plastics, such as PVC, for insulation.
Teflon is also highly durable and can withstand extreme temperatures variations and mechanical pressure conditions without any risk of deterioration.
The PTFE chosen for the Lunar is the extruded rather than the foamed type, since the former is much more robust and maintains the cable structure through cable bending and other mechanical pressures. All these benefits mean that (baring severe abuse) the Lunar will not suffer any wear or depletion in sound quality over many years of usage.
The PREH DIN connectors are filled with a special anti-resonant polymer, selected carefully after listening tests to many damping polymers. The anti-resonant polymer acts as a barrier to reduce the airborne conduction noise from the cable to the connected equipment. The polymer also helps with dampening the plug’s resonances and ringing reduction.
