Engelska filter och nätkabel tillverkaren Isotek, fortsätter att förbättra och imponera på både oss, våra kunder och kritikerna.
Att uppgradera nätfilter och nätkablar är lika viktigt som att ha bra kablage i övrigt.
Att köpa dessa kablar utan att ha upplevt magin kanske är svårt för de flesta. Men om Du litar på alla de rekommendationer som finns ute bland kunder och kritiker, runt om i världen, så kanske just bytet från "lakritssnöret" till nätkabel, och till en Isotek kabel och filter, blir det största musikaliska uppgradering Du någonsin har gjort...

Optimum Link Kabel med Neutrik till C19 kontakt. |
Numera har merparten av Isoteks filter en Neutrik Link utgång. Denna utgång är en ofiltrerad 230V utgång som kan användas för att mata ett andra filter. Ett smidigt sätt att slippa dra ytterligare en kabel bort till vägguttaget om man har mer än ett filter.
Numera finns kablar med Neutrik kontakt istället för Schuko för inkoppling i Link uttaget. |
Overview - EVO3 OptimumThe Optimum is the fourth of IsoTek’s high-performance power cables to be upgraded to the new advanced EVO3 (Evolution 3) version, and is clearly positioned at the top of the range.
The new EVO3 Optimum delivers radical advances over its predecessor, the earlier GII version. Cutting-edge thinking in terms of conductor geometries has been combined with excellent materials to develop a cable of superlative quality.
At the Optimum’s core are three silver plated copper conductors made from Ohno Continuous Cast (OCC) copper. The OCC process for refining copper, developed and patented by Professor Ohno of Japan’s Chiba Institute of Technology, gives a vastly superior level of purity compared with traditional OFC copper. The benefits for audio and AV applications include outstanding electrical conductivity along with improved flexibility and resistance to fatigue and corrosion.
Each of the three 3.0sqmm conductors features a new and innovative square-shaped configuration of 40 strands, each strand also being of square cross-section. This unique design provides an enlarged inter-strand contact surface, further enhancing electrical conductivity.
A high quality Teflon FEP dielectric (insulation) is extruded over each conductor, providing a very low dielectric constant over a wide frequency range. The three conductors are given a slight rotational twist to aid RFI and EMI rejection, and are then surrounded by a cotton filler which, as well is adding internal strength and reducing microphony, also possesses superb dielectric properties – similar to FEP. The whole construction is then double shielded by first enclosing it in a Mylar wrap to provide an additional dielectric buffer, before applying an active OFC copper shield for maximum rejection of high frequency interference. A durable, heat-resistant PVC outer jacket gives a high degree of flexibility and mechanical strength.
Design:CONSTRUCTION: The conductors are in a parallel configuration with a slight rotational twist. This established technique remains the first line of defence against RFI and EMI rejection.
A) Conductors: 3.0sqmm silver-plated Ohno Continuous Cast copper conductors offer a vastly superior level of purity compared with traditional OFC. Each conductor strand is of an innovative square-shaped configuration. The geometry and metallurgy used in this construction offers superb performance with extremely impressive electrical conductivity.
B) Dielectric: Teflon FEP dielectric (insulation) is chemically inert and has a very low dielectric constant over a wide frequency range. FEP possesses a very high degree of stress crack resistance and a low coefficient of friction making it an exceptional dielectric. FEP is the first choice for safety in both temperature and electrical insulation.
C) Filler: Cotton filler has been used to give the cable internal strength and reduce microphony. Cotton also possesses excellent dielectric properties, the best of any solid material.
D) Wrap: A Mylar wrap is used to secure the construction and offer a barrier shield prior to the application of a flexible PVC jacket. The addition of the Mylar and cotton form a buffer with the PVC so as to maintain exceptional dielectric properties.
E) Shield: An earthed OFC shield insures maximum RFI rejection, thus preventing common mode noise affecting the live and neutral conductors.
F) Jacket: PVC is used as an outer jacket to give a high degree of flexibility and mechanical strength.
