DSD to PCM conversion (.dsf/.dff/SACD ISO to WAV, FLAC, mp3, m4a, other files) always alters audio information of the original file. In other words, the processing may be provided with different sound quality. Keep reading the music file conversion guide.
To convert DSD (.dsf, .dff, .iso [SACD ISO]) to/from PCM (.wav, .flac, .aiff, .mp3, m4a) files on Mac or Windows in high quality:
* depending on license type
WARNING: For .iso tracks, .dsf, .dff with lengths more than 3 minutes FREE version mute 2-second silence in the output middle
Noise and distortion levels are important things. They primarily determine audio quality.

The input signal is a sweep sine. In the picture, we can see spectrums of output files for compared conversion software.
In the lower picture part ("a converter software"), we can observe the mirrored image of the input sweep tone. It's distortions or aliases. At the top part of the picture ("AuI ConverteR"), we can view only input sine without unwanted products.
DSD to PCM conversion is based on downsampling. Because, as rule, the input sampling rate is higher than the output one (in instance, 2.8 MHz and 96 kHz, respectively).
Downsampling requires low-frequency filtering. Otherwise, the high part of the input spectrum folds into the audible range of the output signal. Viewed aliases in the picture demonstrate it.
Higher accuracy of conversion requires more computing time.
In some cases, a playback-noise level can be achieved by reducing the output frequency band.
In AuI ConverteR Settings, General tab, see Filter mode list. Playback noise for high-resolution sound files may be solved via "Optimized" filter mode.
Since version 11.x, for professional use, "Optimized G5" filter is recommended to reduce filter ringing length. It is a slow conversion mode.

DSD (Direct Stream Digital) is 1-bit audiophile format family.
PCM is a multi-bit audio format family.
DSD and some PCM formats are included in high-resolution audio.
DSD to PCM is a conversion 1-bit audio format to multi-bit one.
FLAC is PCM audio format.
It's a complex matter. No univocal advantages of DSD audio files comparing PCM ones.
DSD audio format gives technical abilities that have advantages comparing PCM formats. However, it is not so simple.
DSD audio format has some technical advantages comparing FLAC. However, some nuances are there.
DSD128 gives better design abilities to improve sound quality. Primarily, it depends on implementation.
SACD is one of DSD formats. SACD is an optical audio disk that contains DSD audio. SACD may be ripped to DSD file (.iso).
