Mavros interconnect (NEW)
Atlas opens the window wider to reveal more of the musical experience
Specialist cable manufacturer, Atlas Cables, has announced the introduction of what is probably the highest performance interconnect cable currently available; a cable researched, designed and developed in Scotland. The new Mavros cable, which has been designed to be technically and sonically superior to ANY other interconnect cable currently available anywhere and at any price!
The Mavros interconnect uses a new microporous PTFE dielectric together with OCC copper conductors which are manufactured using the highest-quality technique for drawing copper. "Ohno Continuous Casting" or OCC has one grain in about 700 feet of conductor, so the audio signal travels through a continuous conductor instead of traversing grain boundaries. The copper itself is of the highest purity; 6N or 99.9999% pure.
The hitherto highest performance insulator, solid PTFE, has dielectric constant of around 2.1 whilst the new Microporous PTFE foam improves this figure to around 1.5, providing for a 30% greater signal velocity and better integrity, particularly in the area of high frequency delivery.
The construction of the Atlas Mavros Interconnect Cable consists of a pair of conductors each made up from 73 strands of two different diameter wire and each bunch of conductors is insulated by a layer of Microporous PTFE and surrounded by a PEF (‘Mylar’) jacket which is covered by a pure copper close-weave shielding braid ensuring the minimal pickup of RF interference. The outer jacket is made of a flexible PVC material covered by a hard wearing layer of black woven cotton. The Mavros interconnect cable is supplied terminated by the exclusive Atlas direct silver plated non-compressing, double screened, self-cleaning, RCA plugs which are formed from OCC copper thus ensuring a consistent signal path.
In listening tests the Mavros interconnect cable has been shown to be an outstanding product allowing the music to display a natural sense of pace and rhythm, whilst revealing more of the true ambience, depth and height contained in the recording. Indeed it reveals so much more of the recording to enhance the listening experience.
This exciting new interconnect is available now and is typically priced at £750.00 for a one metre long pair of cables.

Notes for Editors:
Microporous PTFE has been used recently in some very expensive cables designed for use with radio and television broadcast systems but Atlas is the first company to bring this sophisticated material into use for audio cables.
Microporous PTFE is a unique, low density dielectric material that offers significant performance improvements over solid PTFE dielectric designs. Microporous PTFE contains a higher percentage of air than solid PTFE; achieved by introducing small
voids (less then one-half micron diameter) of air within the material. The result is a lower dielectric constant (typically dropping from 2.1 to 1.3), corresponding to higher velocity of propagation values, typically ranging from 72% to 85%.
Microporous PTFE has less phase stability vs. temperature variation because this is dependent upon the coefficient of thermal expansion of both the cable dielectric and conductors. And since Microporous PTFE has a lower coefficient of thermal expansion thannSolid PTFE, the use of a microporous dielectric results in less dielectric expansion and so an improved phase vs. temperature response.
For the same outer diameter, cables using Microporous PTFE exhibit a lower loss of signal than those using solid PTFE. This is first, because the low dissipation factor of the dielectric itself reduces attenuation, especially at higher frequencies, and second, the low dielectric constant of a microporous dielectric allows the use of a larger diameter conductor.
The thermal expansion of solid PTFE can have detrimental mechanical effects on cable because as the PTFE expands with heat, it can decrease the air gap between the cable dielectric and connector contact, thus degrading termination impedance. But since the microporous dielectric expands minimally with heat, these effects are insignificant.
In some respects the differences outlined above might be considered to be small but the accumulated effects of these small changes can cause a degradation of the audio signal. Removing that degradation peels away another layer of non-harmonic related non-linearities to reveal more of the music recording.
