Filtering and cables are two ingredients which when combined instantly set off alarms within the audiophile community. That's a silly reaction if you ask us because any cable in fact is a filter already. That’s why all cables have a sonic influence. The real trick is to match the best cable-induced filtering to the rest of the audio chain. [MIT, Transparent, DNM and HSM would agree as all their cable products include filters, some even user-adjustable – Ed.]
Audiomica Laboratory exploit four different filtering methods in their now extensive line of cables. For power cables they use TFCT or Two Filters Current Tension. By applying this filter method to a well-shielded power cable the result is an inline power conditioner. The filter itself is built on a PCB with capacitors and chokes. Protective earth or ground is filtered by the capacitors, the paralleled chokes augment the impedance of the hot and return lines. Interconnects rely on a Double Filtering Signal System. This DFSS filter method uses a duo of custom-made ferromagnets precisely spaced with aluminum, PVC and Teflon. The exact location of the filter element in relation to the interconnect’s plugs is crucial to the final outcome. According to the manufacturer this filter "reduces a variable component in a voltage circuit to move an input voltage closer to a fixed circuit".
Another filter Audiomica Laboratory uses can be found in their loudspeaker cables where it is called the Powder Filtering Signal System or PFSS. Here the main technology is based on air-gapped chokes. They use iron-powder cores for their higher saturation flux density over alloy-powder cores. Together with an exact placement of the filter element on the cable, their filter technology enables Audiomica Laboratory to adjust a cable’s inductivity to the optimal value.
As a fourth filter option in addition to any of the above, the Polish manufacturer uses a Double Screening System. As the name implies there is an extra shield added to a multi-conductor cable where each individual line is already screened. All screening is meant to minimize RF and EMI interferences from both external and internal origins. For review we received a one-meter pair of Pearl Consequence interconnects. Audiomica Laboratory uses the first part of a cable’s name to denote the specific cable whilst the second part indicates the series which the cable belongs to. So the Pearl is a member of the Consequence range which is the current their top of the range.
