How does the MPD-8 process files?
“All digital input signals (including DSD64) are converted to DSD128 with our proprietary frequency and time domain algorithms that also includes an apodizing filter. DSD256 is processed separately. Before the DSD128 or processed DSD256 signals are converted to analog, we use another proprietary and new algorithm to convert the signal to a different format with a bit rate of 2048 (16 times DSD128).”
Why do you prefer DSD processing in your DAC designs?
“Because DSD is single bit it inherently avoids all non-linearity distortions that multibit converters have. Most of the challenges in a single bit converter are on the digital side where you can use virtually unlimited, programmable and mostly very predictable resources to tackle the job. The signal in our converters right before the actual conversion to analog is so close to being analog already, that the conversion is no challenge at all with no exotic components. That makes the system performance very consistent and predictable. Exactly the reason why SACD was launched 20 years ago
