Entreq Olympus High-Current UK Mains Power Cable with QSA Silver Fuse

Entreq Olympus High-Current UK Mains Power Cable with QSA Silver Fuse

Entreq's Olympus line of cables is a testiment to what is possible with Entreq's design philosophy and construction. The Olympus is an impressive product that is likened to a component upgrade as opposed to an additional accessory. Typical feedback for the Olympus cables compares the improvements made on listeners systems to equipment 2x (or more) expensive. Unlike the Argo and triton, the Olympus does come with an external ground connection as an added bonus and it is recommended to pair Olympus cables with the Olympus Ten Ten ground box.

QSA Fuse Upgrade - Available on all Entreq Mains Cables is the option for an upgraded QSA fuse to replace the existing standard fuse. These QSA fuses have been tried, tested and approved by Per-Olof as an immediate improvement to Entreq's power cables, offering performance that compares to alternative cables at twice the price! Entreq recommends the QSA Silver fuse for the Olympus mains power cable as the best price/performance improvement.

10 Unique Characteristics of Entreq Cable Design

1. Separate cable for positive and negative signals to handle magnectic fields in the best way
   This allow Entreq to optimize positive and negative conductors for best performance. Positive and negative conductors have different demands. Many means that they should have same construction for best phase stability, but the benefits with optimize them separately for their job are in our opinion far bigger.
2. Asymmetrical design
   With Entreq's construction, they can choose different metals as well as the dielectric material for positive and negative conductors. The fact Entreq can use different dielectrics mean that they can optimize the polarization effect, so it has so little impact on the signal as possible. Also, Entreq can use different length on the conductors for positive and negative conductors and that allow them to minimize the impact on the signal from the magnetic fields.
3. Positive and negative cables are spun clockwise and anticlockwise respectively
   This together with different length and material on positive and negative conductors/cables give the magnetic fields around the positive and negative cable different shape. This way Entreq can reduce the cross talking betwen the cables and fields.
4. Adapted lengths to minimise the antenna effect
   All cables act as antennas. They both send out and pick up. Some length act as “better” antennas then other lengths. In Entreq's opinion the optimal length for a cable is 4,40 m. Entreq think that length is the worst antenna that pick up less radiation. However, that is not a practical solution to have all cables in that length and also there will be many other negative influences with long cables. Entreq's cables are in step of 0,55 cm lengths, 1.1m, 1.65m, 2.2m and so on.
5. DIC - Dedicated Integrated Contacts
   Entreq make sure that the area and the mass of the contacts area correspond to the cables area. In Entreq's opinion it's very important to keep the signal path as straight and clear as possible. We should avoid bottlenecks and big squares for the signal because it will cause time delays for the signal and the result will be muddy sound. Entreq have also found that it gives big benefits if they use silver for the positive signal and copper for the negative. There are also big differences between solid pins or tubes in the connector. A tube gives better flow for the signal compared with a solid pin. Think of the cable as a Highway. If the access and slip roads are well constructed and in good condition the traffic will flow easy. If it's the opposite, you will get traffic jam and accidents, no matter how good and well-constructed the rest of the road is.
6. Wood in the contact frameworki. Non-magnetic and non-conductive
   All metals are magnetic in one way or another. Even metals/plastic that say they are non-magnetic are “paramagnetic” and have influence on the signal. Wood has no impact on the signal and lets the metal in the connectors signal path work the way you would expect.
7. Only pure copper or/and silver in the signal paths
   No alloys and no metal just for looking good! You never see any metal on a Entreq cable if the metal does not carry signal. Many other brands use big shiny metalparts on the cables for the good looks. But this will be a part of the dielectric and affect the sound quality.
8. Drain wire instead of shielding in order to connet to a pure earth point (External Earth Drains System)
   A common shield of aluminium or copper will also be a part of the dielectric and give undesired results. Instead, Entreq use Infinity treated drain wire of Copper or Silver wich has less affect on the signal, but still protect against radiation. The high pressure treated drainwires (Infinity system) are superior compared with all other kind of wires or shields that Entreq have tested. The Infinity treatment makes the drain work in much higher frequences.
9. EEDS - External Earth Drain System
   This entails the shielding / drain wire not being connected to the device’s negative pole that is the common way. When you do it that way you mix the signal and the pollution just before it enters the device. The result will be that you get it all in the signal/device. With Entreq's EEDS system you keep pollutions and signal separated all the way, from source to receiver. Since the drain wire with the pollutions are connected to another external earth point, (One of Entreq's ground boxes is suggested) the pollutions go to groundbox and the signal go separated and clean to the device. This way, Entreq can drain off the interference/noise that the shielding absorbs to the groundbox outside of the signal paths. A big improvment when kept separated instead of mixed together just before the process in the recieving device.
10. Cotton covering instead of synthetic materials
    The sleeve automatically becomes a part of the dielectric. If using plastic sleeve, you add characteristic to the cables. Some manufacturers want this, but Entreq prefers to add so little features as possible.

QSA Silver Extreme Level Mains Fuse

With more than 22 years of research into what they call 'Bottle Neck Distortion', QSA products can enhance your enjoyment of your system in a way that is remarkable for such a small component, until recently considered irrelevant by many in the industry. Since all current that enters a power cable or component in your system must pass through the fuse before it proceeds, the quality- or lack thereof- of the fuse can make a drastic difference to your system's performance. QSA fuses aim to reduce the negative effects of what QSA describe as 'bottlenecking', which can help your system perform to its full potential.

Much of this may sound outrageous, but only to those who have not had the chance to hear it for themselves. Having conducted our own listening tests, and based on external feedback, we are convinced that these fuses- all the way through the range- offer an upgrade to a system that can match components many times the price.

The Silver fuse is the pinnacle of our current offering from QSA. At the very top of the range, we believe that it can deliver upgrades to your sonic experience that can match far more expensive cables and equipment.
