Yes either PCM Filter 1 ( Also called the Classic FIR Filter ) or Filter 6 ( Filter 6 is also called the Long Fir filter and got more taps Lengts, about 20.000 than filter 1 with an estimate with around 15.000 in tap lenght, but is otherwise vertically identical in frequency response and sharpness and slope pre - after ringing and measures the same in a electric scope.
Classic filter 1
Filter 6: Long filter
Filter 5 Asymmetrical Filter with no pre-ringing but high after ringing:
Classic (left channel blue, right red), Long (left cyan, right magenta), and Asym (left green, right gray) filters (0.1dB/vertical div.).
(Taps: Is a interpolation of the wave lengths dun in the FPGA processor, in mathematics, interpolation is a method for generating new data points from a discrete set of existing data points, that is calculating function values that lie between already known values.
Almost similar to interpolation in a TV with 200 fps frame update / second where the processor looks at the before and after pictures and creates own pictures in betwwen for smoother and more detailed picture from its original 50/60 fp/s )
On DSD it is the filter 1 you chould set it to for the highest bandwith. If you find it to sound to sharp for your ears use filter 2 instead. .
In my opinion DXD mode sounds best on PCM music like streamed music.
DSD Filter 1:
Frequency response DSD Filter 1:
With DSD upsampling you will get a slightly fuller sound and slight more loudness in the low end etc, but not as pinpoint fast and agile, as the DXD mode with PCM Filter 1 or 6 in my opinion.
