It doesn't bypass core audio as that is required for any audio playback on a Mac. It bypasses the part of iTunes that interfaces with core audio and accesses it directly.
That said, I don't get what the OP is after. Everything it does is clearly listed on their website.

Where I don't see it?
Looks like advertising hype to me. What do you mean "clearly listed?"
Why should we spend resources on this product?
What is it suppose to do, and how does it do it?
Other than what Abe mentioned.
Abe> .. for upsampling .. pre-load .. music .. handle FLAC files. <
Up-sampling can be handled by the DAC and Flac can be converted for free. That leaves freeloading, oh pre-loading.
The web page that you sent me to tells me nothing. Maybe you see something I did not see. What did you get out of that advertising hype that was so great you would send me, or anyone else to it a second time?
One purchases this program for improved sound quality with OSX. It is an excellent sounding program.
And you can download it and try it out FREE of charge so there's no risk if you decide you don't want to buy it.
.It is a long list but it pretty clearly spells out most of what it does. Sure there is some hype.. they are trying to sell it. but the list is valid. If you don't understand what the list means then you should ask specific questions. BTW their support is first class so they can answer your questions too.

for someone not to say "Man, this software does a lot of shit." . Unless, of course, the visitor was completely blind.
Just sayin'.
The only OSX music program available that actually bypasses Core Audio is the Audirvana Plus Beta with Direct Mode.
,
Or does the implementation of the software still matter most?
I imagine Channel D will be able to reverse Engineer bypassing Core Audio soon enough.

Good question. After reading about the latest Audirvana with direct and integer modes in Lion I had high hopes. Downloaded the beta and on initial listening I still prefer Amarra 2.4. Sounds more natural, full-bodied and organic to me - less "digital" if you know what I mean.
Thus far I have tried Pure Music, Decibel and Audirvana and have yet to find anything I like as much as Amarra.
Of course this stuff is all subjective and system-dependent...
I'm not surprised with your results. As I wrote in my review, some people will not like Direct Mode/Integer. I think it just removes a number of layers that result in less colored sound.I do think Amarra 2.4 does sound very good, but I am surprised given that you have a Cosecant/denominator. A dac cut from the same sonic cloth as my Crimson/denominator.

Mercman,
while I concur with your statement on the benefits of integer mode, this only applies for in-polarity recordings, for everything else memoryplay, hog mode plus less-is-more is a better way to go. Let's all lobby Channel D to offer polarity- inversion in integer mode
So you're implying that I like a more colored sound? That's a bit pompous - I hate when people say stuff like that. To me, Amarra sounds LESS colored. It's a relative and subjective term.
We all hear things differently.
Let me tell you how I arrive that at these conclusions.First, every component I own is colored in that it has a particular "house" sound. I have spoken to Dave Wilson numerous times about the fact that his speakers refelct what he likes in sound reproduction. I have no idea what is a less colored sounding speaker.
But in evaluating software, I prefer to listen to music that has not sounded right or good to me in the past besides my favorite reference recordings. Here is an example:
Schola Solensis performing Psallat Ecclesia 192/24 a capella music sounded somewhat hard with other software. Direct Mode/Integer eliminated the hardness or stridency I was previously hearing. I was placed closer to the voices with a greater ease and purity to the sound.

Take it easy. I was just pointing out that we had similar dacs but yet heard things differently.But Direct Mode/Integer with Lion is less colored. And that is a fact, not necessarily a preference.

Mercman,
I agree with you and I know you are aware that I have a Wavelength DAC. We all hear things differently and it never ceases to amaze me the number of folk who cannot understand this and take high offense at that suggestion.
Guess Paul Simon was correct; "one mans ceiling is another man's floor.....godaman!"
I think we can all agree that we all hear things differently!
in YOUR OPINION it's less colored.
I'm sorry I gave you a hard time on this. Enjoy what sounds the best in your system. I guess I'm a bit over enthusiastic about integer in Lion. I didn't wish to fmak you.
No prob - no hard feelings - I enjoy your posts and it was your review that made me want to check it out.
Cheers.
Great information, thats the answer I was looking for...
Sometimes less is more, but then sometimes its not. It takes a real balance to fine tune things in audio. But one good thing is, at least it was done, so now we know at least its possible. This is not to say that direct-mode will or will not have a positive effect with other software if they decide to use it.

Both if you wish to play integer with OSX Lion. But the implementation does make a difference. I don't know what Pure Music is up to.
Its nice to have choices, rolling software can be as fun as rolling tubes...esp if they all sound good in their unique way.
