'Sacks took some time to explain why the Native DSD team has been an early leader in offering Multichannel DSD downloads at a time when most sites only offer music downloads in Stereo and Mono. When recording new albums for his Channel Classics label, Sacks prefers recording in concert halls and live venues rather than a recording studio. This approach allows Channel Classics to capture natural ambience, depth and imaging.
Sacks says these attributes of music can best be heard in Multichannel playback. He noted that "When Multichannel recordings are done right, you will be convinced of the need for Surround Sound in your system."
