  • Pure silver conductors: Under normal conditions, silver is the best electrical conductor.

Cable capacitance plays a decisive role, especially for audio cable connections between individual devices. As the signal sources are very weak and react sensitively to high cable capacitance, audio cables are virtually predestined for air insulation using air helix technology.

Adding another highlight to this perfect audiophile foundation, we then focused on the conductor material of the cables. Copper in the appropriate purity is already a very good conductor. A superconductor, where electrical resistance is zero, would be perfect, of course. Unfortunately, superconducting materials require temperatures of at least -70 degrees. Under realistic operating conditions, the best conducting material we have is currently silver. At 61.35 S/m (Siemens pro Meter), its conductivity is approximately six percent superior to that of copper. However, this precious metal is about 100 times more expensive.

New XLR 180° plug: It is only possible to insert XLR connectors in one direction. This can be annoying as the position of the XLR sockets in devices varies. In order for the cable to fit, it must sometimes be twisted by force. This puts a strain on cables, plugs and device sockets and sometimes simply looks a mess. The newly developed XLR 180° plugs can each be rotated by +/- 45 degrees, i.e. +/- 90 degrees in total. The finishing touch for perfect cabling.

Thanks to the Air Helix design, the conductors run freely suspended through the length of the cable.

The Air Helix architecture permits signal conductors to be insulated to practically 100% by air. Special clips were developed to provide the supporting framework. Positioned at defined intervals inside the cables, these clips keep the helically-arranged conductors apart. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from each other. This architecture is unique, bringing low capacitance and minimum dielectric losses – a true milestone in the search for open and unadulterated sound.

Our physical approach: Minimize losses for true-to-original playback.

Our Referenz AIR cables transport audio signals between source, amplifier and speaker in an authentic way and with a minimum of loss. You can enjoy music that precisely expresses the emotions of the artists at the time of recording – sensual, subtle, light-hearted or orchestral right through to full-blooded and rocking. Vocals and instruments are delivered in unadulterated form. Everything remains vibrant and full of emotive energy. Favorite tracks and pieces continue to trigger strong feelings even when you’ve heard them a hundred time over.

To the point

AIR Helix

The Air Helix architecture enables the signal conductors to run freely suspended through the length of the cable and permits signal conductors to be insulated to practically 100% by air.

The dielectric

Using air as a dielectric lowers capacitance to a minimum. In comparison with other insulators, using air as a dielectric leads to no increase in capacitance and creates no dielectric losses.

Multicore structure

By cleverly arranging the conductors in the multiply nested multicore structures, overlapping magnetic field areas are created that significantly reduce inductance.

The conductors

The Cross Link Super Speed waveguide avoids so-called skin effects and delivers a balanced sound, even with complex music passages and high volume levels.

XLR 180°

The Referenz XLR 180° connectors developed by us can be rotated by +/- 45 degrees and can therefore be optimally adapted to individual socket alignments. Cables and sockets are less stressed.

Point-to-point Air Helix for end-to-end connections

A new feature in the 5th generation of in-akustik’s Air Helix architecture is the point-to-point connection. Specially designed transitions are available for each type of cable and connector. Across the complete length of the cable – point-to-point AIR Helix. It may sound trivial at first, but the results are impressive. Sound signals are transported with minimized losses, right through to the final centimeters. The sound is more detailed and dynamic than even before.

The conductor structure

The Cross Link Super Speed waveguide avoids skin effects caused by eddy currents in the conductor. Thanks to the braided structure, the waveguide is able to precisely transport even extreme current peaks. A lacquer coating around each wire prevents eddy currents within the conductor and protects against oxidation. All this results in a conductor that delivers a balanced sound consisting of vibrant and never overemphasized timbres, even in complex musical passages and at high volume levels.

Pure silver conductors

Pure silver is regarded as the best conductor, delivering more detail across all frequency ranges. The charismatic sound of pure silver is primarily due to its high drift speed. Pure silver cables shouldn’t be confused with silver-plated cables. Silver-plated cables are said to lend a metallic and aggressive character to the sound, something pure silver cables never do.

The shielding

EMC interference, from sources such as mobile phone and WiFi networks, is constantly increasing. This interference impairs the sensitive audio signal. Interference occurs when signals of different frequencies overlap. This can result in unwanted distortions that have nothing to do with the original signal. Dense shielding is therefore essential to protect the extremely sensitive music signals from this interference so that even the finest details are preserved.

Cable manufacturing unit

The beating heart of in-akustik is our manufactory. This is where our success story is rooted – permeated by a congenial working atmosphere, a love of music and a passion for detail. At in-akustik, we believe musical enjoyment stems from a listening experience that remains as close as possible to the original recording and the artist’s interpretation of the piece. That’s why we boast a committed workforce that combines curiosity with a keen sense of precision. With a fascination for music and things that are really special – like the development of our complex AIR cables.

Handmade

Each cable is handcrafted with the utmost care. Our extensive know-how and the qualifications of our team enable us to manufacture the complex cables in a customized manner. Apart from the finest of materials, our most important resource is the manual dexterity of our cable assemblers. In assembling our outstanding cables, they demonstrate meticulousness, composure and dedication.

Rigorous quality control

We manufacture in accordance with the highest standards. Rigorous quality control is carried out before, during and subsequent to assembly. We verify the tolerances of ever individual component. At every stage of manufacturing, we check the configuration and electrics for short-circuits. We also conduct functional and mechanical testing. No product leaves our manufacturing unit without a final quality check.

Did you know...

...that our NF-1205 AIR (2 x 1.5 m) is made up of 254 individual components? The pure silver wire used is 855 m long, and the PE monofilament is 334 m long. Containing 208 drill holes, the Air Helix design of this cable type demands great dexterity on the part of the assemblers when they’re threading through the conductors.

XLR 180° connector

Conventional XLR connectors are designed for fixed positioning, which often forces the cable to twist. This load causes increased mechanical stress. In contrast, our proprietary XLR 180° connector offers a unique and adjustable alignment that allows the connector to be rotated within a range of +/- 90 degrees. This flexibility not only reduces the mechanical stress on the cable, it also enables optimum alignment of the cable in relation to the device sockets, which are often arranged differently from device to device.

Rhodium-coated

The best cable requires optimum connection technology. We use tellurium copper, a harder metal alloy that maintains the high conductivity value. Much superior to that of brass connectors. The rhodium coating ensures long-lasting contact and corrosion resistance. The stable conductivity is even maintained with frequent conversions. This is better than gold contacts, which wear out quicker.


PE network jacket

Most cables have a PVC sheath surrounded by a textile or plastic braid. This sheath is meant to protect the cable from mechanical damage. At in-akustik, we deliberately don’t use a PVC sheath in order to avoid capacitance and any consequent dielectric losses. The sheaths for AIR cables are made of polyethylene monofilaments. These hold the conductors tightly together, reduce microvibrations and allow extreme dynamic peaks to be processed in an unadulterated fashion.

Timely and insightful
Format: Hardcover
As Clay Risen thoughtfully makes clear, the Red Scare of this era had roots in earlier decades, and its effects continue to be felt today. The parallels between those years, which included the HUAC and the Hollywood blacklist, and today provide an important examination of 20th century American history. As he writes in the Preface, "Self-described patriotic organizations proliferated, intent on ridding their communities of Communism; one, the Minute Women, had some four hundred chapters nationwide. Parent-teacher organizations, school boards, civic clubs, and Boy Scout troops all came under scrutiny. Hundreds of books were purged from public and school libraries." Reading about the people and stories of that time, you will recognize them again today. I also very much enjoyed his description of how the idea for this book first came to him--as moments from childhood memories which inspired years of research and analysis, and finally this engaging, thoughtful book!

A well-lively account of a recent and unsavory period of American history, roughly 1946-1955.
Format: Hardcover
Red Scare is a well researched and a very readable account of a significant moment in post-World War II American politics. The author situates the rise of the Red Scare in a right-wing reaction to the New Deal, the labor unions, and any forward progress towards civil rights for black and other non-white Americans. The Red Scare gathers force in the Republican Party following a long frustrating period in which the Democratic Party coalition led by FDR remained in power and reshaped the federal government to counter the Great Depression and then mobilize the nation for total war on multiple fronts in Europe and the Pacific. At the beginning of the Cold War, politicians like the young ambitious Richard Nixon find Red-baiting the Democratic Party opposition leads to electoral success in post-war Congressional races. The Republican Party secures a majority in the Senate and the House following the midterm election of 1950. Risen shows a reactionary movement gathering momentum from the Cold War geopolitics that shattered expectations for the peace and security that Americans had hoped for when the war ended in victory. In the wake of the defeat of the Axis powers, Americans felt threatened by the spread of Communist-backed and Communist-inspired regimes, first in Eastern Europe and then in China, then the Korean peninsula. Although the US and Russia were ideologically distinct, they cooperated during the War to defeat their common enemy, namely Hitler and Nazi Germany. But the conclusion of the war brought a decisive end to that cooperation. Instead, there was a series of confrontations in Greece, a divided Germany, and the Eastern European bloc of nations that the Red Army occupied and kept tightly controlled. Roosevelt’s coalition had embraced progressive and socialist proposals like Social Security and the Wagner Act that protected workers’s right to organize and collective bargaining. The Red Scare marked the beginning of a reactionary response to roll back those policies. Meanwhile, the elaborate security apparatus of the Federal government that was empowered during World War II was re-directed against left-wing groups that FBI Director Hoover targeted as “unAmerican.” There was also justifiable alarm that people like Klaus Fuchs spied for the Soviets and passed them much of the secret sauce in the technology developed at considerable expense around the atomic bomb. Risen’s book plays all the hits from that ignominious period: the House Committee on UnAmerican Activities (HUAC), the Hollywood 10, the Alger Hiss affair, the China Lobby, the Smith Act prosecutions against the American Communist Party leaders, the trial and execution of the Rosenbergs, loyalty oaths and blacklists, the persecution of J. Robert Oppenheimer. They are all here. The book chronicles the rise and fall of Senator Joseph McCarthy, and the colorful personalities around his political career including the attorney Joseph Welch that the Army hired to confront him, the TV personality Edward R. Murrow, and his ruthless and feckless henchman Roy Cohn. He sees McCarthy more as a symptom than a cause. Risen shows how Eisenhower, elected President in 1952 on the Republican ticket, co-opted and ultimately blunted the anti-Communist crusade in favor of a less confrontational, more moderate approach. Eisenhower also had a visceral reaction to personal attacks carried out on the integrity of George Marshall for “losing China,” having served under Marshall during the height of his military career. The book also highlights the Supreme Court’s decisive change of heart, under newly appointed Chief Justice Earl Warren, that reasserted 1st Amendment and 4th Amendment rights against guilty by association prosecutions. In many places of the book, the author empathizes the many continuities between the rabid anti-Communist rhetoric and tactics of the early 50s with the right wing politics of the present day, particularly in the area of Public Education.
