check this out..

http://www.compaxx.org/

as per them

In both listening and laboratory tests, CompaxxTM ‘remasters’ benchmark at more than 50% playable data than even the finest CD’s. The result is an entirely new threshold of definition and frequency response that is compellingly clear, rich, and startlingly lifelike in authentically recreating the dynamics of originally recorded performances.

do not know how true this is.. will check out with a Comparison sometime.. but the future sure is interesting

I happened to check out the difference after downloading both the CD and the Compaxx versions. Contrary to what the site claims the Compaxx version is atleast 3 db louder in level than the CD version hence maybe sounds more open and detailed. Maybe the Compaxx encoding is technically better, but the comparison does not seem to be fair.

I have only auditioned on my PC speakers which are cheap, run of the mill class. The difference is definately noticeable. Yet to hear them on my Stereo setup.

Cheers.

This looks to be interesting.
But technically I really dont know how is this possible ?

The inherent algorithms that are used to MP3 compression, surely compromise on the quality of the audio data.

But if what the site claims is true, this is surely a news to dig further into.

Just had a listen to the samples. Seems to have better detail. But that could also be an effect of accentuation of the higher frequencies and a significantly higher gain. Dunno! Like, Behram said - gotta listen on a good stereo for a longer time to know.

I checked out their stuff using a few of their samples. The file size of both the version are almost the same. The Compaxx versions were generally a little louder at the same volume level (though they do mention that the volumes have been normalized). This could also be the reason they seemed to be a little more revealing. The spatial imaging seemed clearer in them. The bass seemed more well defined though some of the low freqs tended to sustain longer. There was some background noise in a couple of the tracks (most evident in The Nutcracker) but maybe that is the indecipherable data they are talking about

Compaxx recommends the use of A 3-piece-or-better multimedia speaker set to listen to the samples. I used my Sony MDR-W014 Lightweight Sports Stereo Headphones. The tracks were played using Winamp 5.2 with flat tone settings.

The Compaxx versions do seem to be much clearer and richer in their quality though I am still a little concerned about maintaining the naturality of the recording. Their restoration and enhancement process may introduce some unnatural elements, its digital logic after all. Performance enhancing steriods! But this was not very evident in the sample tracks I checked out, only the CCR track seemed pumped up. In a nutshell, from what I experienced, it definitely seems to be an advancement on the digitally compressed audio. So finally we may get the hard core audiophiles and analog lovers in the same fold as the download and burn gang.

The tracks I compared with:
King Crimson - Cat's in the cradle (I didn't know that they have also covered this. Didn't sound like them either)
Floyd - Another brick 2
CCR - Fortunate Son
Vivaldi - Four Seasons, Autumn allegro
Tchaikovsky - The Nutcracker
