EVO3 Optimum

At the Optimum’s core are three silver plated Ohno Continuous Cast (OCC) copper conductors, with each conductor strand being of a square configuration for tighter bunching. The OCC 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 give internal strength and reduce 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.

Features

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.

TERMINATION: The Optimum cable is terminated using IsoTek’s bespoke audiophile-grade connectors of solid OFC with 24ct gold-plated conductors. These offer the highest quality performance and are less prone to tarnish.

Solid OCC Copper Ag

As one would expect the internal wiring of any IsoTek product is of the highest standard, ultra pure Ohno Continuous Cast copper solid core conductor strands with silver-plating offers low resistance and high amperage. A Fluorinated Ethylene Propylene (FEP) helix is wound around the conductor before an extruded FEP dielectric protects the conductor and creates a Virtual Dielectric of Air (VDA). This construction gives unrivalled performance and gives the ultimate low resistance, high performance internal power delivery system.

IsoTek’s internal wiring synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.

High Grade Components

Every IsoTek product uses the finest grade electrical components, many custom made, using the highest quality metals and materials which are specifically designed for purpose. Quality doesn’t stop at parts but also extends into the PCB designs, which maintain high levels of amperage and extraordinarily low levels of resistance, using up to eight times the general standard of copper prior to pure silver plating.

Internal wiring also uses high purity coppers combined with silver plating, with either Fluorinated Ethylene Propylene (FEP) dielectric or IsoTek’s Virtual Dielectric of Air (VDA), where a FEP tube is wound around the conductor before an extruded FEP dielectric protects this construction giving unrivalled performance and the ultimate low resistance, high performance internal power delivery system.

Sturdy - Easily Adjustable - Works as Advertised
I modified it to fit a small subwoofer under my desk. I flipped the arms, inverted them and screwed it on to the desk. Not the intended use, but it solved my issue perfectly. It's really sturdy, it'll be perfect for mini PC's.

Flexibility and clean desk space!!!
Bought three of these for my home office. Two for Synology NAS drives and one for a Mac Studio. The size ranges make this the perfect product to get everything off my desk. A little difficult to install with the desk upright so I suggest turning it on its side or over completely. In my case, I have these in sit stand desks which is great.

Decent bracket, Non-beveled screw holes cause complications
The screws that secure the mount to the underside of the desk stick out enough to cause the inner dimensions to change. I had to use the next hole down to increase the size of the bracket to accommodate my device, resulting in a less secure mount than desired. If the holes were beveled so that the screws fit more flush with the mount I'd be able to give it 5 stars. But the inner dimensions are not entirely as advertised due to the screws. Quality is up to standard otherwise, installation is relatively straightforward, price point is fine for a bracket of this size.
