Audiophile-grade components (NS9100ES)
Two capacitors with identical circuit values can have quite different sound quality. For this reason, Sony® engineers have taken the time to choose top- quality
Sony's choice of a grounded AC input assures a more stable electrical and mechanical connection.
Gold-plated output jacks.
To maximize electrical conductivity and minimize the effects of oxidation over time, the audio, composite video,
You might not notice that the output jacks are plated with gold. But they protect the audio and video signal quality from oxidation which can degrade the output signal over time. And that can make a noticeable difference.
