I really want to say a few words about this feature. The technical passport is published on the official website, no matter how you look at it, this is a stripped-down version of 9038! ? The biggest feature is a more energy efficient hyperflow modulator. What is the source of this energy saving? At first glance, I see two points from the script: 1. The reconstruction filter is worse, the removal of a brick wall, the addition of an extra minimum phase, the filter attenuation is worse. 2. Low-frequency hyperflow modulator, asynchronous mode mclk (MasterClock) 9038 is 100 MHz (> 2048 fs), and 9039 is 50 MHz (1024 fs). You should know that the data in the official 9008 document is all 40 MHz, does that mean it's done backwards? . . This mclk is associated with the final modulation process, affects the formation of noise, and also directly affects the resolution.
Although in general, while maintaining the same parameters, energy consumption decreases, and it would not be an exaggeration to call it an "upgrade", but again, the measurements are the same, and it sounds like devices that are very different from each other, surely all enthusiasts have met. This adjustment of retention parameters cannot be considered simply as an "improvement". For those who can already play 9038, why do we need 9039?"
