free and PVC-free.

Sometimes size does matter, as in the oversized filter capacitors of

Sony's STR-DA3100ES.

Spider Ground Plate

Amplifier designers often assume that the various circuits inside the

chassis all "see" a common ground. Unfortunately, slight differences in

grounding can have a subtle impact on the sound. That's why Sony created a

Spider Grounding Plate for the STR-DA3100ES and DA2100ES. The plate

establishes a "standard reference ground" for all circuits and reduces common

impedance.

Sony's Spider Grounding Plate uses ten points, plus substantially

thicker connections to achieve a standard reference ground.
