Help with PCM, 96khz/24bit, 176.4khz/24bit FLAC, DSD, Double DSD, Quad DSD, MQA, WAV, etc


I am considering downloading some musical files and am very confused on the above formats.   Is it better to download 96khz/24bit files or DSD Files?  

The Reference Recordings website offers several options including 176.4khz/24bit FLAC or 176.4khz/24bit WAV.   Several other options are available but these seems to be the best.

HIGH RES Audio exclusively offers high-resolution music downloads in Studio Master Quality in FLAC, ALAC, DSD, DXD-FLAC and MQA format.

All my current albums are stored in AIFF format on my Aurender N10 Music Server.  I might be willing to experiment with some of the above formats but I am more interested in listening to the music than spending time deciding on the best format.  These above formats might sound better than my PCM albums but is the sound quality really that much improved?  

Audio technology is continuing to improve and, it seems, new formats and solutions are always being introduced, such as MQA albums.   What new formats can we expect next?

If I decide to decide to download some files, what formats should I be using?  Your suggestions and comments are welcomed.

The encoding is different from the file type.  So FLAC, ALAC, WAV, AIFF, etc are all file types that a music file can be saved as.  This is independent of the resolution and bit depth.  The file types I mentioned above are ubiquitous, and most all audio players and DACs support these file types.  Furthermore, there are audio file translator applications that can take a FLAC file and make it into a WAV file, etc.

Before I get slammed by the community, let me say that what I posted in the first answer to the OP is a simplification of the terms and concepts in digital.  I am sure someone can find something not quite right about my response, but more or less, it is accurate.

As for the difference between the (lossless) compressed file types of ALAC and FLAC versus the uncompressed file types of WAV and AIFF, a lot has been debated on this.  I listened and could not discern a difference.  I chose AIFF in the end for my music collection for more theoretical reasons.  In order to compress a file, with or without quality loss, the original file needs to undergo compression by means of a compression algorithm that finds way to make the file size smaller.  When the music will be played, this compression needs to get undone in reverse.  My way of thinking is, storage is cheap and plentiful, I would just rather that the files avoid this extra step.  In short, I just don't require the space saving of the FLAC and ALAC.  I chose AIFF as I am a mac user, and this is the native mac uncompressed audio file format.

As for the sound of the Tidal MQA files, I have not listened closely enough yet.  I have a Tidal HIFI membership, and I use Roon to stream the music to my PS Audio DAC.  Roon and PS Audio do not yet have a full MQA unfolding implementation.  I can bypass Roon for now and get the MQA unfolding with my DAC, but I like Roon, and the regular CD resolution files from Tidal sound great on my DAC.  Once Roon offers an update, I will be happy to listen to more of the Tidal masters!
Hgeifman, don't worry what file type you purchase for now.  FLAC is fine.  You can try another later if you like, but for all that I can tell, lossless is lossless, and the files are good.

Have fun!

@marktomaras, Thanks for your above comments.  Since HD Tracks offers the AIFF option, I will use it.  All my current albums use AIFF and it works fine.  
FLAC files need to be decoded/decompressed along the way, a potential source of issues (probably very minor). 

AIFF is an uncompressed format similar to WAV, but unlike WAV also has the benefit of supporting metadata and cover art. AIFF files take more disk space and longer to download. AIFF files work using iTunes.

All my current albums were ripped using the AIFF format.  I do not like the coding and decoding required for FLAC files.  I am still researching and am leaning toward using the AIFF format for my Hi Res downloads.  

I am going to defer on using DSD files for now.  



We think alike :-)
I trust DSD is great, but so is high res PCM. 
I listen to 70% vinyl, so until I upgrade to a DSD DAC, perhaps in a few years, I am happy with any files that are CD quality or better.
Hey guys .. just want to point out "uncompressed flac" (via dBpoweramp) has been around for a while now. This option is not "0 compression" btw. Basically, it’s a wav file with metadata. I switched from aiff after years of metadata issues (mostly minor).
