The text says S8 uses a specifically designed low noise PLL module from Titans Audio Lab.
But are not all IC’s you can buy “specifically designed” for their intended use a little dose marketing speak , I’ll bet it also has audio optimised op amps too or similar . Anyway seems like a good device , but with the marketing going overboard a bit . That’s not unusual, having the obvious stated , like low noise and distortion and low jitter . That’s what I expect out of DAC no one needs to tell me that , backit up with some measurement that shows why this approach xxxx can do a little bit better than yyyy . Often there are many ways to achieve similar results ?
