AuI ConverteR give you ability of easy .iso file ripping. To convert SACD ISO to DSD (DSF, DFF files) on Mac or Windows in high quality, follow the steps below:
AuI ConverteR uses the best (by its developer's opinion) sound quality settings as default. Also, you can opt settings by your taste.
Also, read about SACD to DSD (optical disk ripping).
WARNING: AuI ConverteR 48x44 doesn't support DVD-audio and DVD-video.
AuI ConverteR processes too-long file names and paths, non-Latin and forbidden characters (created from metadata) for successful output file writing. Third-party utility decodes SACD ISO for additional processing with AuI ConverteR. Read the whole page carefully.
* If .iso is supported in the purchased configuration. When you convert the first time read about (auto codec downloading and installing).
** If it's available in the purchased configuration
*** All prices on this page are in U.S. dollars without V.A.T. and other applicable taxes and fees. The prices are recommended. Information on this page is not a public offer.
For ISO tracks, DSF, DFF with lengths more 3 minutes FREE edition mutes 2-second silence in the output middle.
Converted stuff is placed in the target directory.
Dithering is ignored when extracting ISO to DSF.
AuI ConverteR has several price/functionality options that allow saving your budget for the required functionality. You can expand Modula-R abilities later by purchasing new modules. Unlimited-time license, major updates (... 10.x > 11.x > 12.x > ... versions) are paid.

To listening to SACD optical disk, special drive is used. As rule, computers are not capable to play back a Super Audio CD. However, the disk may be ripped to SACD ISO or DSF or DFF files.
SACD ISO, DSF, DFF are 1-bit DSD audio file types. To listening such files, digital-to-audio converter (DSD DAC) and player software is required. The audio player software should provide native DSD support.
Direct ripping to DSF and DFF files may cause some issues. DSF supports metadata (song and album info) better way than DFF. Extraction to DSF with some software may cause clicks at the file end.
SACD ISO files may include stereo and multichannel (5.1 surround) variants of the same album. Mobile phone or portable player have stereo output for headphones. Limited space of hard disk or SD-memory stick is used to excessive audio stuff that you don't listen.
You can extract either stereo or multichannel album variant to DSF or DFF audio files. Also, multichannel music may be downmixed to 2.0.
SACD ISO is a container file with DSD tracks (songs) included in a music album. .iso file may contain mixes (variants) of an album: stereo and/or multichannel. Also, we can meet the similar DSD ISO term.
The file contains audio in 1-bit sigma-delta modulation with sample rate 2.8 MHz (a.k.a. DSD). The author hasn't information about higher sample rates in the .iso-file.
The ISO to DSD extraction may be done in bit-perfect mode. Both binary contents in the container and into extracted DSD files are identical. It is possible for 2.8 MHz (DSD64) sample rate only.
Equipment has several playback modes (audio resolutions), that can cause individual distortion level of each mode. Using of mode with minimum distortions can improve sound quality. Read details here...
Also, you can convert DSD ISO to .dsf/.dff files with resampling in extraction. It allows playback of these files "natively" on DAC that is DSD128 and higher capable.
In the ideal case, should not be noise in the audible band. Lesser noise (darker background) displays higher sound quality of converter SACD ISO to DSD.
We can compare noise with sea waves.
Lesser noise is like smaller quieter waves.
We can listen to music clearer when background wave noise is quieter.
A multichannel variant may be played back at a multichannel system or downmixed 5.1 in 2.0 to playback at stereo equipment or headphones.
Downmixing may be performed inline ("on fly" into a player) or offline. "Offline" means: convert ISO to DSF 2.0, with or without downmixing, before playback via a music converter. Offline stereo extraction/conversion saves disk space on hard disk of portable musical devices. Therefore you can place more music on a digital music player or mobile phone.
Also, read some sound quality issues below.
Conversion ISO to DFF is not recommended. Because DFF doesn't support metadata (song, album names, performer, year, artwork) standard way. Theoretically, metadata may be built into DFF technically as non-standard information block. However, playback software/hardware will ignore it, as rule.
If the target sample rate is D128 / D256 / D512 / D1024, resampling processing is used. Resampling processing based on filtering. These filters have several settings.
At Settings > General tab:
On some equipment "Non-Optimized..." filters can cause audible noise: watch the video.
"Optimized..." filter is recommended for most cases.
Check/uncheck Use minimum phase filter switch for minimum/linear phase filter respectively. "Non-Optimized..." filters have linear mode only.
SACD ISO files may contain 2 album variants: stereo and multichannel.
Portable devices (DAP, mobile phone) have:
As rule, portable device is intended for stereo playback.
An audio player software has 2 options:
In case #1, excessive hard disk space of mobile devices is consumed. And lesser music-file number may be placed on the mobile device.
In case #2, additional computing resources (and energy too) are consumed. Additional energy consumption reduces the time of autonomous work.
To solve cases #1 and #2, the extraction of stereo DSFs may be used.
If ISO contains a multichannel variant only, downmix 5.1 to stereo may be applied.
a) Don't open content of iso file that is mounted in a virtual drive. Open *.iso file with AuI ConverteR directly.
b) To view SACD ISO content (album name, performer, year, stereo/multichannel variants, track number):

SACD ISO may contains stereo and multichannel variants of an musical album. It consume additional space at hard disk. It is significant factor for mobile devices.
To solve the issue, stereo variant may be extracted or multichannel one is downmixed.
Sound quality of SACD ISO to PCM extracting is defined by implementation. So, qualitative extraction may be used for further bit-perfect PCM playback.
Also, sampling rate and bit depth may be matter for sound quality.

In a recording/playback audio system, DSD format allows passing some stages theoretically. So it may be a way to reduce distortions. However, the audio-system design is matter.
