If you want to convert DSF to DFF with absolutelly same sound quality (bit-perfect).

You have several options to optimize an audio file to your DAC.

Resampling filters

If you want to resample DSD files, you can use AuI ConverteR. You have options, that allows adjust sound for your requirements.

In Settings > General, you can see 4 resampling filter modes that define the output band:

Optimized mode (20 kHz output audio band; recommended);
Non-optimized (up to 24 kHz, depending on input and output sample rates);
Non-optimized Wideband (up to 100 kHz for DSD files, depending on input and output sample rates; a traditional band for PCM to PCM conversion).
Optimized G5 mode (20 kHz output audio band; shorter ringing length; slower; recommended for professional use);.

If #2 and #3 modes cause audible noise at your hardware, then use #1 or #4 mode.

You can compare sound (see Settings > General > "Use minimum phase filter" switch). When the switch is checked in Optimized mode (#1) "quasi-analog filter" is applied. In modes #2, #3, #4 the switch is ignored.
