ES DVD Players 2005, Version 4.0 Page 2 Intr oduction Sony ES engineers are superbly educ ated, exceptionally well equipped and have ready access to world-leading in-house technologies. But these alone do not explain the soul of Sony's ES Se ries. You see, the creators of these components are motivated by their passion for music and movies. Th[...]

ES DVD Players 2005, Version 4.0 Page 3 i.LINK ® and HDMI™ Digital Interfaces In 1985, the engineers of Sony® ES surprised the world of high fidelity. The Sony CDP-650ES was the world's first CD transport with a digital output, enabling unheard-of sound qual ity and unprecedented flexib ility in audio system configuration. Now such interfa[...]

ES DVD Players 2005, Version 4.0 Page 4 Typical SA-CD reproduction involves numerous D/A and A/D conversions. The i.LINK digital c onnection can simplify the s ignal path. However, these analog connections can expose the Super Audio CD signal to repeated D/A and A/D conversions. The i.LINK® interface of the DVP- NS9100ES overcomes this limitation.[...]
