Restore a Cartridge

Le Son was founded in 2015 by Gregory de Richemont and Dr. Ted Tsai, the engineer behind our ECC generator

Technical discipline, deliberate material choices and careful listening shape every decision we make

The same standards follow every cartridge we build or restore, and every owner we guide

Gregory de Richemont & Dr. Ted Tsai

Founders

Four cartridges, each with a different generator, winding and output level

The right choice begins with the phono stage you already own

LS10 MKII

The original Le Son, still the only one built around Dr. Tsai’s ECC generator

LS10 MKII “S”

The LS10 wound in 5N OCC silver, with a 0.5 mV output that suits most MC phono stages

LS10 MKII “G”

Our lightest generator, for phono chains with the low-noise gain a 0.1 mV cartridge requires

SL1 MKII

The moving-coil principle, through the MM phono input you already own

“For demanding audiophiles like us, the Le Son LS10 cartridge strikes a remarkable balance, and elevates the vinyl listening experience to new heights.”

Z. Guoliang • Stereo Sound Magazine

“It’s hard to convey what an impressive example of design, engineering and execution that Le Son has achieved in the LS10 MKII.”

M.L. Gneier • TNT-Audio USA

“The Le Son LS10 MKII ‘G’ moving coil phonograph cartridge will not be the weak link in your stereo system.”

Jerry Seigel • 10 Audio, Perfect 10 Award

“Fantastic cartridge and great value

The LS-10 MkII is an incredible cartridge at a great price. Tonally, it’s as close to perfect as I’ve ever heard, and I’ve been messing with audio systems for 45 years. I finally have the sound in my living room that I’ve been searching for.”

“Very nice boutique brand

Very nice boutique brand, combining high quality with a direct to consumer approach. From the packaging to the product the experience was flawless. But now the most important. The sound is awesome.”

“This cartridge ROCKS!

Aside from it being the most beautifully packaged and finished cartridge I now own, it is articulate and tracks super quiet while bringing out the best in all the vinyl I’ve played to date.”
