LYRA KLEOS SL “Single Layer” low-impedance, low-output model<\/strong><\/p>\n\n\n\n

This is a special, built-to-order, version of Kleos for expert users with very high-gain, extra low noise phono stages, or alternatively a step-up transformer designed for phono cartridges of 2 – 3 ohms or less.
Most users (and phono stages) will benefit from the regular Kleos with much higher output and considerably more energy; resulting in a much better signal-to-noise ratio. If you are in doubt about which version of Kleos that will work best in your system, please go with the regular Kleos.
The Kleos SL may provide extra pure and pristine sound from an audio system that is optimized for a low-impedance, low-output cartridge. However, this may be accompanied with a lesser level of energy and power.
Lyra nevertheless has decided to offer SL models, as built-to-order at a 10% surcharge, for those who are confident that they can extract the benefits from such a low-output MC phono cartridge.<\/p>\n\n\n\n

Continuit\u00e9 d\u2019un succ\u00e8s annonc\u00e9<\/strong><\/p>\n\n\n\n

Lanc\u00e9e d\u00e9but 2010, la Delos a fix\u00e9 de nouvelles normes de qualit\u00e9 \u00e0 un niveau de prix tr\u00e8s comp\u00e9titif. C\u2019est un succ\u00e8s retentissant et nous tenons \u00e0 remercier tous nos Revendeurs et leurs clients qui sont \u00e0 l\u2019origine de cette r\u00e9ussite. La nouvelle orientation des bobines mobiles inaugur\u00e9e par LYRA  sur la Delos, surnomm\u00e9e \u00ables vinyles sous un autre angle<\/em><\/strong>\u00bb, a un impact significatif sur le suivi du sillon par la cellule, produisant un son plein, avec beaucoup de mati\u00e8re, extr\u00eamement naturel. Lyra  a \u00e9t\u00e9 fier d\u2019introduire cette innovation sur sa cellule d\u2019entr\u00e9e de gamme mais nous avions aussi h\u00e2te d\u2019entendre les effets de cette innovation technologique sur des mod\u00e8les plus \u00e9volu\u00e9s !<\/p>\n\n\n\n

Le Roi est mort, vive le Roi<\/strong><\/p>\n\n\n\n

\u2026 et la nouvelle Kleos est arriv\u00e9e. Sa lign\u00e9e est de bon augure: l\u2019originale Tsurugi (1976), Clavis (1991), Clavis DC (1995), Helikon (1999), et maintenant la Kleos. Comme pour l\u2019Helikon, en production depuis plus de 10 ans, nous sommes convaincus que la Kleos fera partie  des cellules les plus appr\u00e9ci\u00e9es pendant de tr\u00e8s longues ann\u00e9es.<\/p>\n\n\n\n

La masse de la Kleos a \u00e9t\u00e9 augment\u00e9e par rapport \u00e0 l\u2019Helikon. En effet, le corps principal de la Kleos est plus massif que ceux de ses pr\u00e9d\u00e9cesseurs. Il est usin\u00e9 en duralumin et re\u00e7oit un traitement de surface satin\u00e9 argent  du type utilis\u00e9 pour certains appareils photo haut de gamme.<\/p>\n\n\n\n

Outre la nouvelle disposition des bobines, Jonathan Carr, a dot\u00e9 la Kleos d\u2019un diamant \u00e0 courbure variable (taille propri\u00e9taire LYRA) pour combiner temps de propagation de groupe id\u00e9al et facilit\u00e9 d\u2019installation. Comme sur les mod\u00e8les haut de gamme Lyra, un cantilever Ogura (en bore) est utilis\u00e9.<\/p>\n\n\n\n

Aucun aspect important (mais souvent \u00ab oubli\u00e9 \u00bb), pour le son final, n\u2019a \u00e9t\u00e9 n\u00e9glig\u00e9. Ainsi le transfert d\u2019\u00e9nergie entre la cellule et le porte cellule a fait l\u2019objet d\u2019une \u00e9tude approfondie et des solutions innovantes ont \u00e9t\u00e9 retenues.<\/p>\n\n\n\n

La surface de contact autour des trous de fixation est profil\u00e9e pour concentrer la force de contact de la cellule sur la coquille de mani\u00e8re \u00e0 am\u00e9liorer le transfert d\u2019\u00e9nergie. De m\u00eame les cosses de raccordement sur la cellule sont sp\u00e9cialement \u00e9tudi\u00e9es pour supprimer toute r\u00e9sonnance et elles sont introduites en force dans le corps de la cellule pour diminuer l\u2019\u00e9nergie des ondes stationnaires qui pourraient interf\u00e9rer avec le signal. Ces cosses sont plaqu\u00e9es en PLATINE.<\/p>\n\n\n\n

Ecoute<\/strong><\/p>\n\n\n\n

Le son de la Kleos plaira \u00e0 la fois aux fans qui retrouveront les qualit\u00e9s qu\u2019ils appr\u00e9cient \u2026  et aux d\u00e9tracteurs de l\u2019Helikon. La rapidit\u00e9 et la dynamique sont naturellement pr\u00e9serv\u00e9es, et la capacit\u00e9 \u00e0 cr\u00e9er une image pr\u00e9cise, large et profonde, qui a fait sa r\u00e9putation est sensiblement am\u00e9lior\u00e9e.<\/p>\n\n\n\n

Les am\u00e9liorations apport\u00e9es \u00e0 cette nouvelle cellule sont importantes et elles r\u00e9pondent aux demandes des utilisateurs de l\u2019Helikon : la capacit\u00e9 de suivi (en raison du nouvel alignement des bobines) et l\u2019\u00e9quilibre spectral sont en grand progr\u00e8s. Le meilleur suivi procure une pr\u00e9sentation plus douce du medium et de l\u2019aigu. La Kleos est extr\u00eamement silencieuse. L\u2019abaissement du bruit de fonds permet d\u2019acc\u00e9der \u00e0 un niveau de r\u00e9solution tout simplement extraordinaire. Le r\u00e9sultat global est un nouvel \u00e9quilibre spectral, l\u00e9g\u00e8rement plus chaud. Pas rond et\/ou \u00e9touff\u00e9, plus chaud. Moins de bruit, plus de vinyle.<\/p>\n\n\n\n

Poursuivant notre \u00e9valuation de la  Kleos (s\/n 001), nous avons recherch\u00e9 la force d\u2019appui optimum. A 1,77 gramme, nous avons trouv\u00e9 le \u00ab sweet spot \u00bb d\u2019une mani\u00e8re totalement \u00e9vidente. Reproduction plus silencieuse et plus dynamique au point de para\u00eetre plus forte \u2013 instantan\u00e9ment. \u00c9tonnamment facile !  A partir de l\u00e0, le r\u00e9glage de la VTA est une partie de plaisir.<\/p>\n\n\n\n

LYRA KLEOS “New Angle” stereo<\/strong><\/p>\n\n\n\n

The New Angle on LP Reproduction:
The Lyra Kleos MC Phono Cartridge<\/p>\n\n\n\n

Although many MC cartridges have good performance, their sound is held back by how they are designed. The problem is, the signal coils should have the same angle as the magnetic circuit during playback, but MC cartridges are typically designed so that the opposite happens – applying normal tracking force pushes the coils out of alignment. This impairs coil sensitivity and linearity, and reduces sound quality.<\/p>\n\n\n\n

Lyra’s “New Angle” technology solves this fundamental problem by compensating for how the signal coils are affected by vertical tracking forces, and optimally aligning the coils when it matters most – during playback. Introduced on our entry-level Delos, the New Angle technology enables the Delos to perform well above its pricepoint.<\/p>\n\n\n\n

But being audiophiles, we wanted to achieve the next higher level – which is the new Kleos. Building on New Angle technology, the Kleos innovates with a stronger chassis machined from aircraft-grade alloys, narrowed mounting area to improve energy transfer, and pre-stressed construction combining multiple materials with non-parallel surfaces to inhibit internal body resonances. The fully hand-made Kleos also has a Lyra-designed line contact stylus and platinum-plated output pins, achieving an exceptionally quiet noise-floor with superior immediacy, resolution and tracking, wide dynamic range and explosive transients, plus a warmer and natural tonal balance. The Kleos is a high-value cartridge that surpasses the sound quality of substantially more expensive cartridges.<\/p>\n\n\n\n

Let the Lyra Kleos show you how good a New Angle on LP reproduction can sound.<\/p>\n\n\n\n

A bit more detailed information: KLEOS<\/strong><\/p>\n\n\n\n

The Kleos is the lowest cost Lyra cartridge to feature the full fledged Ogura manufactured boron cantilever and coil system with Lyra original line-contact (3 x 70\u03bcm) stylus. This is similar to what is employed on even the most expensive Lyra models.<\/p>\n\n\n\n

Nevertheless, the most important element of the new Kleos is it’s sound. We firmly believe that the Kleos is capable of extracting more information from the vinyl grooves than it’s predecessors, and that the reproduction of music is both more dynamic, more detailed, and more natural than the models preceding it. We also are of the opinion that the Kleos will set a new standard for sonic performance at it’s price point.<\/p>\n\n\n\n

Today there are only a small handful of master cartridge builders in the world, and Lyra’s Yoshinori Mishima belongs to this elite group of individuals that are capable of crafting the highest level MC transducers on the planet. His assistant Akiko Ishiyama, who has undergone several years of apprenticeship, is also involved in the building process leading to each Kleos. The Kleos is not only hand made, but each cartridge is listened to extensively and “voiced” by the master cartridge builder, like the finest musical instruments.<\/p>\n\n\n\n

Lyra offers a unique combination of capable, advanced cartridge design by Jonathan Carr and complete handmade execution by the above mentioned individuals. Investing in a Lyra Kleos through an authorized retailer will offer you an unparallelled analog experience from your stereo microgroove vinyl records.<\/p>\n\n\n\n
