Folio - a cut-down version of the Athenaeum for audiophiles with smaller music collections.

The main specifications are identical to the Athenaeum. However, the Folio comes with only two internal drives, which are not removable. This means that the storage capacity of the unit cannot be increased, but the data can still be mirrored across two drives for complete security.

Zone Client - for use with either the Athenaeum or Folio to extend the physical range of these systems. It contains the same audiophile hardware and specialist software as the music servers but does not have any local storage; instead the music is streamed from the music server to the Zone Client. This means that different music can be played in different parts of the building; all controlled using the same touchscreen remote control.

Furthermore, because the music is distributed digitally to the Zone Client and then through an amplifier and speakers, the analog path is kept as short as possible. The shorter the analog path, the less chance there is that interference or loss will degrade the audio quality.
