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.

Great quality, hummingbird nectar all in one bottle!

I was so excited to get this hummingbird nectar because you don’t have to add anything to it at all. When I was reading the ingredients, it does have a preservative so that’s good as well. It won’t go bad on the birds. I love it. I saw my birds coming and going to this feeder all day. I highly recommend it.

Birds seem to love it!
Size: 16 Fl Oz (Pack of 2), Style: 16 Fl Oz Concentrate (Pack of 2)
I grew up using homemade hummingbird food dyed a bright red color with koolaid or food dye. But for the first time in my adult life, I'm somewhere that has a lot of hummingbirds and I wanted to provide them with the best juice possible. I decided on this juice because I like that it has hummingbird friendly electrolytes and is in a concentrate so I can make my own preferred dilution. I am in a very hot desert climate so I've been doing a 1-3/3.5 ratio to help keep them extra hydrated and the hummingbirds and bees are loving it. We have four feeders. Two closer to the ground and two on our second floor balcony. The birds and bees have been visiting all four regularly and our cats are loving the show. I swear my youngest cat gets most excited about the bees. I know the bees are seen as problematic for most but the birds don't seem to mind them sharing a few feeding holes and we don't mind feeding the bees too. The bees are probably more important for our ecosystem than the birds anyway. I took away one star because the seals on the bottles aren't very strong and both had leaked during transit, one was very messy and crusted with dried sugar. Since these are technically supposed to be refrigerated after opening I probably should have returned them but upon reading the ingredients, I don't see a reason that they would have gone bad without showing obvious signs of spoilage. It's basically gatorade for birds. I even took a sip to see if I died. I was fine so figured it's fine for the birds too. If the next order is also leaking I'll consider going elsewhere but for now we have happy birds, bees and cats.

They keep coming back for more ..........
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
I've only been using this food for two weeks, but the hummingbirds love it so far. From what I've read, they are attracted to the color of the feeder more so than the smell of the nectar / food itself. With the amount of work that hummingbirds have to go through just to find enough food to survive, I figure it is worth the extra cost of this food compared to making plain sugar water that does not have the added minerals and electrolytes that this feed has to mimic real nectar.

Great product
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
I bought this same product last year for my hummingbirds and it brings them into the feeder. So, as of today I have already seen a steady increase in the hummingbirds. 💕
