Lyra make exceptional cartridges!  We do not stock any above the Delos, but better yet to order one fresh from the factory - call us anytime to do so!

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 70μm) stylus. This is similar to what is employed on even the most expensive Lyra models.

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.

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.

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.

Kleos SL:

The Kleos SL 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.

Kleos Mono:

This is a special, built-to-order, mono version of Kleos for real mono playback of monaural/monophonic (mono) microgroove, vinyl records. It is recommended that the Kleos Mono is used with high-gain, low noise phono stages, or alternatively a step-up transformer designed for phono cartridges of 2 - 3 ohms or less.

On mono records, the vertical axis of the groove contains no musical information, but it will frequently have noise, in the form of groove damage and dirt. The Kleos Mono has therefore been designed to be completely insensitive to the vertical axis, which greatly improves the signal/noise ratio without any downside on monaural records.

The coil former is a square permeable plate oriented parallel to the record surface rather than the 45-degree angle used for most stereo cartridges, while the coils are wound so that they only generate a signal when there is horizontal movement of the stylus and cantilever when tracking a record.

Two totally separate monaural coils are used in the Kleos Mono, since most monaural cartridges are used with stereo amplifiers and stereo speakers. The separate coils also help avoid possible ground loops and hum problems that could otherwise be caused if a single coil is fed into a stereo two-channel amplification system, thereby tying the two channels together electrically.

In addition to parallel mono connection to a stereo system (two amplifiers and two speakers), it is also possible to leave one set of connections unattached for pure mono playback with a single amplifier and a single speaker. However, it is also possible to connect the two mono channels in series for additional output when used in a pure mono system. Use a short cartridge headshell lead wire with female pin-connectors to connect either the Kleos Mono's upper right pin with the lower left pin, or alternatively the upper left pin with the lower right pin. Then use the two remaining unused pins for connection to your single amp RIAA input (alternatively a transformer input). The two internal channels are now "chained" in serial-connection for additional output and energy when you only use a single amplifier and a single speaker.
