Kleos SL Moving Coil Cartridge

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.

Description

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.

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.

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.
