The assymetric2 (self-shielded technology)

Based on our assymetric1 but in a heavier version, assymetric2 is a cable that takes the two mains characteristics of a modern cable (very good sonic performance at a moderate price) a step forward. Music sounds more clear and neutral with a smooth and extended frequency response.
The assymetric2 is a very light flexible non-shielded (unshielded) twin-core interconnect cable in bright-green or warm-yellow color.
These types of cables are much less reactive to the signal than conventional fully shielded cables. In this way they have generally been perceived to sound faster, less coloured and more open than their fully shielded counterparts. On the other hand, nowadays all kind of uninvited and undesirable noises such EMI, RFI, vibrations etc. produced by our home devices -including mobile phones- enter these "nude" cables, causing audible signal distortion.

Assymetric2 consists of unique configuration characteristics to minimize this problem using our self-shielded technology.
The use of assymetric2 further increases the balance and transparency in any reproduction system in its category. Providing excellent digital signal transmission quality the assymetric2 is also recommended for use as a very good digital interconnect.
The two signal conductors are specially made of 99.999% (5N) extra soft temper pure fine silver, which has the best conductivity of all metals. The manufacturing process eliminates the surface mechanical anomalies improving the electrical signal transmission properties, giving extremely low distortion especially in high frequencies.
Each one of them is perfectly cleaned using a specific cleaning procedure which eliminates corrosion, and polishes the surface in order to increase conductivity and prepare the conductor surface treatment.
To eliminate the problem of silver corrosion in the course of time, a thick liquid treatment oil is being used, specially designed for this purpose. The same oil is standardly applied to all our extra soft temper pure fine silver conductors. The result is a time-lasting stable product capable of avoiding chemical attacks, protected from atmospheric pollutants. This liquid treatment also works:

  • As a metal to dielectric suspension, reducing the vibrations coming from the current running through the audio cables and the loudspeakers themselves, rendering any microphonic effects insignificant.
  • As a lubricant, reducing dramatically the friction between the silver conductor and the dielectric tube avoiding the static electricity (conveyance of electrons) distortion.

By using a specific process, each end of our silver conductors is perfectly polished, thus becoming elliptical to avoid electric evacuations.
The insulation tubing of the two conductors is made of PTFE, which is the original TeflonŽ formulation and has the lowest dielectric constant of all plastics. The conductors have the least possible contact with the insulation material according to the first principle of our sToa 8 technology increasing velocity of propagation.
Total cable capacitance is a very low 28pF/m adding the clearest sound you could ever imagine to this unusual cable.
We use single signal and signal return conductors providing similar field geometry per length unit.
Likewise, the use of a single conductor for signal and signal return eliminates chaotic electron migration through the usual conductor strands and their imperfect barriers.
By twisting the two silver conductors together and keeping cross-sections small we reduce magnetic hum and skin effect. The small twisting lengths minimize the exterior interjections, causing the signal transmission to travel at faster speeds.
Using a unique anthropocentric mathematical algorithm we manage to make different lengths in the twisting process providing a significant diminution at the internal interjection between the conductors. This assymetrical "
self-shielded technology" dramatically facilitates distortion rejection produced by the electromagnetic interface (EMI) and the radiofrequency interface (RFI), rendering the use of an external shield practically insignificant providing a good balance between shielded and unshielded "nude" interconnect cables and thus negating the otherwise notorious dilemma.
The sonic result is so clear and relaxing, that you are treated with an unforgettable experience.
Our patented Natural Flow Cooling System keeps the conductors temperature stable and quite low, increasing conductivity and eliminating farther corrosion as any chemical activity. Moreover this cable is airproofed by carefully isolating the sensitive silver conductors out of the atmosphere and the penetration of humidity keeping the capacitance stable and low.

An arrow printed in the outer label indicates the direction as the signal flows from the source.
Finally, a thin double layer halogen free jacket of 3.8mm external diameter provides excellent flexibility, electric insulation, and durability to this "musical transporter". This layer is independently hanging to the connectors using our patented Elastic hanging mechanism, offering significant advantages thus rendering assymetric2 practically uninfluenced by any alteration in the wires metal structure.
Total cable weight remains remarkably low (21gram/m) in order to protect your delicate equipment sockets.

The assymetric2 interconnect cable is available with our minimal metal content, gold plated RCA high quality connectors. These superb conductivity connectors are designed to present significant low capacitance.
Before lead-free and halogen-free soldering, using high purity, 4% silver solder, we apply pressure to stabilize the conductors and ensure a suitable low resistance contact. The process of melting and solidifying takes place within narrow temperature ranges so that the surface of the solder joint remains smooth and corrosion-protected. This connecting method seems to provide the best signal transfer results.
A thick liquid treatment oil is applied on the solder surface as well as on all our RCA connectors to eliminate corrosion increasing contact electrical stability. In addition, each connector is protected from dust and corrosion by a red soft plastic heavy duty cover cup. After unpacked we recommend not disposing the plastic cover cups. Use them in order to protect the unused RCA sockets to your amplifier from moisture, dust, corrosion and any accidental insert.
Before packing we use our cables demagnetizing method neutralizing all metal and non-metal parts on them in a three-stage procedure.
Finally, as with all our cables, assymetric2 interconnect cable is carefully checked and separately tested in our laboratory by a highly skilled master technician to ensure a reliable product and a blissful owner, offering a significant upgrade to your valuable audio system.

Assymetric2 is carefully packed in a luxury real wooden box specially designed to protect this cable and prevent any damage. Each of our wooden boxes has a unique serial number same as the cable. Inside you will find all documents and instructions manual required plus a bottle of our pastra advanced antistatic cleaner as a gift.
