In the 1600s, craftsmen and builders had a problem. They were being asked to build increasingly monumental structures: grand cathedrals, palaces, and intricate canal systems. The tools they had on hand for leveling, like water levels and plumb bobs, weren’t accurate enough to safely reach the structural heights demanded by the architects and financiers.

Leveling errors in vertical and horizontal structural elements compound themselves as buildings grow taller. 

Then something extraordinary happened. French scientist and polymath Melchisédech Thévenot invented the spirit level. This ingeniously simple device—a glass vial partially filled with liquid, with an air bubble that naturally finds its center—revolutionized everything from architecture to engineering. In one fell swoop, Thévenot bridged the gap between ancient techniques and modern precision, laying the groundwork for centuries of meticulous craftsmanship and scientific exploration.

The idea of a simple tool revolutionizing the world isn’t new: the compass, the telegraph, the vaccination needle.

For us audiophiles we have one great tool at our disposal. Our ears and our experience.

How many of us cannot walk into a room and identify whether or not a system is sounding good?

We don’t need a spirit level or expensive test gear to verify that which we can in one instant hear for ourselves.

Consider yourself a craftsmen.
