Lyra Kleos SL

Product Code: LYC013SL


ex-vat: £ 2,579.17

The Lyra Kleos SL is a special version of the standard Kleos, but with a single layer (hence, the “SL” designation) of coils, resulting in lower mass.

Lyra describes the SL series as follows:

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… [It] may provide extra pure and pristine sound from an audio system that is optimised for a low-impedance, low-output cartridge. However, this may be accompanied with a lesser level of energy and power.

If weight of sound and dynamics are your priorities, go for the non-SL version. But if high resolution and speed are what you’re seeking, and you’ve got a suitable phono stage or step-up transformer, the SL version may be ideal.
