1. Stereo WAV DXD 24BIT/352.8kHz
2. Surround 5.1 DXD (WAV) 24BIT/352.8kHz
3. Stereo DFF DSD 64 2.8224Mbit/s ("*.dff" does not work with DeadBeef)
4. Stereo WAV 24BIT/96kHz

Everything works on Arch Linux (OSS4) with DeadBeef and Petrov's "scientific plugin", except for "*.dff" format.
The sound quality of those HiRes audio files is really fantastic (with Sennheiser headphones for audiophiles). You can play them even on a very old computer of 2001 (with downsampling), and, after downsampling to 48kHz with the Russian "exact scientific resampler", they sound much better than audio CDs.
The OSS4 drivers for Intel HDA soundcards (e.g. ICH7) support 32bit 192kHz format. Such soundcards can be found on many notebooks (2005-2011).

Petrov's "scientific plugin" for DeadBeef (free, but "closed source") is somehow distributed among the Russian "secret esoteric society of audiophiles".

We invite you to join us in this evaluation of future consumer delivery formats. FLAC is a lossless encoding of WAV-files derived directly from our production original used for the SACD and Pure Audio Blu-ray. All resolutions and encodings are derived from the same original DXD source files. Please send us an e-mail and share your experience on your practical experience with these file formats. Enjoy the music!
Digital eXtreme Definition is a professional audio format that brings "analogue" qualities in 32 bit floating point at 352.8 kHz. DXD preserves 11.2896 Mbit/s (4 times the data of DSD). http://www.2l.no/hires/index.html
In short, such HiRes audio files are now available for free download, and these HiRes formats are suggested to be "future consumer delivery formats", simply because everyone already knows (except, perhaps, for ALSA users and Linux developers) that the so-called "Nyquist–Shannon Sampling Theorem" is a "stupid science for idiots and crazy lunatics" http://en.wikipedia.org/wiki/Nyquist%E2 ... ng_theorem
In theory, 32bit/352.8 kHz. DXD format might have a kind of "analogue qualities".
In practice, they simply record crap and sell it to mass consumer markets:
It's taken me over 200+ concerts to develop my equipment to this level of "analogue realism" and I still get surprised when I hear the offerings of professional companies such as NAGRA, PRISM, GENEX etc, which fall far short of the standards in sound reproduction of the 1950's-60's. You can easily hear their shortcomings in current recordings made with them. http://www.metaxas.com/pages/masnewfiles/index.html

This is simply a kind of "profit maximization behavour". Otherwise, if you do not sell crap to naive consumers, you may not survive in competitive market.
With digital [audio CD], overtones go missing, ambiance goes missing...Hell, IMO, the music goes missing. I think the digital [audio CD] can have more spurious info because of the numerical approximation, but true musical detail, not possible...
If you listen to crap [that is, audio CD] played through crap [e.g., ALSA], how can you possibly ascertain quality reproduction? http://www.audioasylum.com/cgi/t.mpl?f=vinyl&m=5232
Blu-ray players are also crap.
Our DIVERTIMENTI is 100% according to the official Blu-ray specifications. Unfortunately all players are not. Due to the 192 kHz rate in MCH, not all 1st generation players has the processing power required for decoding, and therefore “cut corners” and down-sample or down-mix to stereo. http://morten.lindberg.no/19537/
Audiophiles were invited to buy Blu-ray players and Blu-ray Discs, for it was believed that they are stupid and deaf. It was a "deliberate deception" [gezielte Täuschung], and this deception was momentarily detected by true audiophiles. As a result, nobody wants to buy Blu-ray players and Blu-ray Discs anymore (except for the ignorant). This is the reason why Morten Lindberg published the "true HD audio files". He is trying to convince audiophiles that it is not a fake.
In addition to linear PCM in 24/192, DTS Master Audio and DD True HD is offered on DIVERTIMENTI with the purpose of convincing audiophiles of their true lossless qualities. http://morten.lindberg.no/19537/
It seems that Morten Lindberg is playing a kind of "open source" game with the customers. Do not forget that Blu-ray Discs were strongly encrypted to prevent audiophiles from studying the quality of the content of Blu-ray Discs http://en.wikipedia.org/wiki/Blu-ray_Di ... ent_System
Notice that ALSA is so advanced that it cannot play 192kHz samplerate without downsampling viewtopic.php?f=3&t=4387
