The Alto Top Plate is machined from a solid billet of aluminium with a further aluminium inlay bonded with AVDC, for trapping masking vibrations.

The precise machining of the Alto Top Plate ensures for perfect flatness and immunity to warping, the Alto Top Plate is much thicker than the original at 5mm deep.

There are 6 plinth mountings and both these and the suspension bolts featured are supplied securely fixed in place. The Alto Top Plate provides the most robust alignment of the spring retaining bolts that is fundamental to the long-term performance of the deck.

The Alto Top Plate can be combined with upgrades from Tenor, Alto and Soprano ranges and comes in a choice of black or silver finish.
