Frequently Answers and Questions

What is the difference between DSD and PCM audio formats?
DSD (Direct Stream Digital) is a high-resolution audio format that uses a single-bit delta-sigma modulation scheme. PCM (Pulse Code Modulation) is a lower-resolution audio format that uses a multi-bit linear quantization scheme. DSD is generally considered to be a more accurate and natural-sounding format than PCM.
What are the benefits of using a USB D/A Converter?
A USB D/A Converter can improve the sound quality of your music by converting the digital signal from your computer to an analog signal that can be played through your stereo system. This can result in a more accurate and natural sound reproduction.
