Soprano Sub-Chassis

Machined from solid aluminium with our unique honeycomb design and a built-in tonearm collar, this is our ultimate sub-chassis upgrade.

For years, Stack Audio has been requested to make an all-in-one sub-chassis and arm board, so we did just that.

The Soprano Sub-chassis is machined from one solid piece of aluminium keeping those same key tolerances achieved with the Alto Sub-Chassis and Alto Armboard.

The hexagonal pattern is prevalent throughout the structure, making it lightweight but perfectly rigid. Within the hexagonal pockets you will find precision made AVDC inserts for trapping masking vibrations and dissipating them as heat.

Unlike the Alto Armboard, the Soprano has a fixed tonearm collar, encompassing it securely. With a perfect spindle to pivot distance, it allows the needle to follow your records precisely and unmasking their true potential.

The Soprano Sub-chassis comes in both Linn and Linn Ittok arms.
