priceless new tool. For audiophiles, it’s a major step closer to pure music.
Not surprisingly the DVP-S9000ES audio section makes extensive use of technologies originally developed for the world’s first SACD player, the Sony SCD-1. Here are the highlights.

Direct Stream DigitalTM Encoding:

A Foundation for the Future

For nearly 30 years, digital audio has been based upon Pulse Code Modulation (PCM) technology — and nobody knows PCM better than Sony. We’ve used it to develop everything from Compact Disc and DAT to professional DASH recorders and digital mixing consoles. But to achieve a truly fundamental breakthrough in music reproduction, Sony has invented a truly amazing audio technology: Direct Stream Digital (DSD) encoding. DSD encoding is destined to serve as the foundation for digital audio in the future.

Simplifying the Signal Path

Even the most advanced PCM record/playback systems require decimation and interpolation filters that can cause problems, including requantization noise, passband ripple and ringing. These degradations can smear musical overtones, muddy the soundstage and compromise overall transparency. A radically simpler approach, Direct Stream Digital processing eliminates these problems by eliminating the filters! It enables a 1-bit signal to be recorded directly.

Beyond Comparison

Direct Stream Digital processing is dramatically different, even when compared to the most sophisticated PCM technology. This 1-bit system encodes music at an astonishing 2,822,400 samples per second. The result is more than just superb frequency response and dynamic range. You’ll hear the inner detail of choral ensembles. The reverberation trailing from a guitar chord. And the acoustic space surrounding the instruments. With DSD technology, you hear every nuance of sound reproduced with incredible ease and clarity.

1.RF Processor. For all types of disc, including DVD, this circuit performs clock signal extraction, synchronization, demodulation and error correction.

2.DSD Decoder. For SACD only. Authenticates the SACD invisible watermark, separates text from music and forms the left and right DSD pulse trains.

3.ACP System. For SACD only. Controls the influence of switching distortion.

4.VC24 Plus Digital Filter. For CD only. A supremely advanced version of the familiar 8x oversampling digital filter.

5.Current Pulse D/A Converter. For SACD and CD. Supremely accurate conversion from 1-bit digital to analog.

6.Low Pass Filter. The SACD analog low pass filter helps deliver frequency response to 100,000 Hz, unprecedented in a home audio source component.
