Sony N59100ES User Manual page 41

In addition to its remarkable technology, the DVP-NS9100ES continues
the "cascade" faceplate design exclusive to the Sony® ES Series. The design
sets all the primary controls at an angle, so that you can identify each control and
use the player without uncomfortable bending. The silver colored faceplate is
made of brushed aluminum and fits in beautifully with conventional audio
components. But the design really comes into its own when the DVP-NS9100ES
is combined with other silver cascade components, such as the STR-DA7100ES
or STR-DA3100ES.
The STR-DA7100ES shows how the Silver Cascade design extends to
receivers. The design is also featured on the STR-DA3100ES.
