שרשור תגובות עבור המאמר: תערוכת האודיו ב- CES 2014: יש מסקנה ברורה
מיכאל, המהפך נראה בכיוון של מעבר ל-DSD, יש גידול יפה בחברות שמתעסקות עם תכנים בפורמט
מיכאל, עכשיו מתחילים להוסיף תמיכת Native בהדרגה וגם תמיכה ב- Level 2 האיכותי יותר. בנוסף, נראה שיש התייחסות רצינית גם ברמת התוכן וזה טוב.
Careful consideration was given to providing the highest possible reproduction of DSD files by the Alpha DAC Reference Series. 99% of modern DAC’s, including the Alpha Reference Series use mult-bit D/A converters because they provide better performance than 1-bit converters – even those who advertise “native” DSD compatibility. So, at some point, the 1-bit DSD stream must be converted to multi-bit for all of those DAC’s.
We could, like many other manufacturers, convert 1-bit DSD to multi-bit within the Alpha DAC Reference Series and show “DSD” in the front panel display. That would be the easiest approach from a marketing perspective. But that would also mean increasing the amount of processing in the DAC during playback which would degrade audio quality, and audio quality is the reason the Alpha Reference Series exists.
Fortunately, virtually all reproduction of DSD files using external DAC’s occurs with a computer based music server as the source. If the 1-bit DSD to multi-bit conversion is done first in the computer it can be performed with extremely high precision and superior filtering that preserves all of the content of the DSD file. Computer DSD to multi-bit conversion can be at least as good as that performed in a DAC and without adding processing noise near or in the D/A converter chip. Another advantage of computer based DSD to PCM conversion is that if higher performance DSD versions such as DSD 4x appear in the future they can easily be supported with a software upgrade.
For all of those reasons, DSD capability for the Alpha DAC Reference Series is provided by an included state of the art software application that provides either real time conversion of DSD 1x and DSD 2x to 176.4 kHz 24 bit PCM during playback or conversion to 176.4 kHz 24 bit AIFF or WAV files. The software application is included in the price of the Alpha DAC Reference Series and is compatible with either Windows OS or Mac OS based music servers.
