Vibration Free Support

The VFS and CLASSIC VFS (for AMP and for Source) is a system consisting of two solid aluminum plates, placed one above the other to eliminate external mechanical vibration. Vibration absorption is often underrated in hi-fi systems, and should be studied carefully so as to get the best out of the equipment. All electronic circuit boards inside Nagra equipment are mounted on special silencing-blocks anyway, but the VFS allows you to go one step further in truthful sound reproduction.

Vibrations can be externally generated, caused by the acoustic waves of the music, transmitted through the ground (a nearby traffic for example) or even by mechanical playback of CD or LP.

The VFS uses  a technology developed for the space agency, consisting of a very special damping material that allows a dramatic vibration damping and shock absorption. Each half of the VFS uses a different cushion to absorb a specific range of mechanical frequencies, which is why the VFS consists of a double layer of plates, that must be used together.

Tube equipment is far more sensitive to vibration than solid state devices. This is why VFS are highly recommended on Nagra tube equipment.
