Precision
instruments.

SAT designs and builds the world's most rigid turntables and pickup arms — purely mechanical instruments engineered to extract every detail hidden in the groove.

"You will never find magic ingredients in my designs.

I cannot make magic — only the best of what science, technology, and my imagination have to offer today."

Gomez holds a Master of Science in Mechanical Engineering and Materials Science, with a career spanning the Ariane rocket engine, the Porsche Carrera GT and Rolls-Royce waterjet engines before turning to vinyl replay.

He treats a pickup arm as a precision instrument, not a tuned musical instrument. Materials and geometries are chosen on the laws of physics and proven engineering practice — never on myth.

Laminated, not off-the-shelf

Special aerospace grades of carbon fibre are laid in a specific orientation, then autoclave-cured with the same equipment used for satellite composites — placing fibres exactly where stiffness must be highest. It is then CNC machined and sanded to achieve the final geometry and satin finish.

CAD · CAE · FEM

Moment of inertia, natural frequencies and modes are calculated before a part exists. Virtual design of experiments allows us to explore and evaluate a much greater number of designs to reach the optimal configuration when compared to traditional prototype testing.

Higher frequency, lower amplitude

A stiffer structure resonates at higher frequency and lower amplitude. The higher the resonance frequency, the less intrusive it is during playback. The CF1-09 tube has its first and second natural frequencies at 4 030 Hz and 9 000 Hz, keeping distortion out of the music.
