Liking this player (never tried it before today). Only settings I changed was turning off automatic gain protection, enabled 64 bit processing, and resampling from quality to audiophile. I can probably change the resampling back to quality. Source is a .dsf file. (DSD256).
EDIT: I just noticed the bitrate. Dang!
You might also want to have dither and sound shaping turned on. This will allow oversample to work better, and make the improvements more precise. Generally how oversampling works (for this case scenario), is that it averages the noise (based on the multiple chosen) and then does its thing (obviously there is a lot more to it, but trying to keep this short). It is like trying to divide on a calculator. It will give the nearest number it can while dropping the remainder or often referred to as the modulus in math and programming (remember teacher telling you to show your work when doing math? I hated it..
).
Using higher multiples of oversample can add those remainders up and that can actually amount to potentially significant noise. BTW! oversample will also make your digital filters more noticeable as a side effect, as well as increasing the dynamic range. But, the caveat is that it also increases the signal-to-noise ratio because summing up uncorrelated noise increases its amplitude.
This is where dither comes in. It actually adds noise to the track. This will supply enough noise for oversample to work more precisely at the chosen multiple (rather than as a whole). If this noise is still within the human hearable frequency (generally below 20Khz), sound shaping comes in. It is simply an algorithm that converts this noise to a known "out of reach" frequency.
Sound shaping (combined with dither) will convert the noise to such a frequency that the human ear cannot hear it. This will result in the cleanest sound that you can get from the current technology. Whether it sounds better to your ears is subjective, but scientifically, it helps (combined with other technics; FPGA master, isolated batteries, etc...) to produce the cleanest sound that the DAP can produce (unless some other tech comes out at some other point).
Hope that all made sense (best way to explain it without basically writing a white paper...
), and sorry for another book...
