Isotek EVO3 Optimum Power Cable


EVO3 Optimum Power Cable

Isotek Power cables are now available on the Gold Coast, call Terry at GC HiFi on 0419448452 to discuss what length and Isotek model cable you may require. We use the Isotek Optimum in our high end HiFi systems with excellent results.

Three silver plated Ohno Continuous Cast (OCC) copper conductors form the core of the EVO3 Optimum, with each strand being of a square configuration for tighter bunching.

The OCC process offers a vastly superior level of purity with outstanding electrical conductivity, improved flexibility, resistance to fatigue and corrosion. A high quality FEP provides 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 confers internal strength and reduces microphony.

The whole construction is enclosed in a Mylar wrap to provide an additional dielectric buffer, before applying an active OFC shield for maximum rejection of high frequency interference. A durable PVC outer jacket gives a high degree of flexibility and mechanical strength.


  1. Pure silver plated Ohno continuous cast copper for exceptional conductivity
  2. 3.0sqmm conductors give higher amperage aiding power delivery
  3. Thick square conductor strands group closer and improve performance
  4. Fluorinated Ethylene Propylene (FEP/ Teflon) allows increased performance
  5. Multi-strand cotton filler mains dielectric constance
  6. Mylar wrap improves Common Mode noise rejection and maintains cable structure
  7. Oxygen free copper braid increases Common Mode (RFI) noise rejection
  8. Flexible PVC jacket


“EVO3 Optimum turns in an extremely impressive performance. The improvement it makes is profound and should leave no one in any doubt about the importance of mains power.”
