I thought I would point out the use of your word, since you don't mind saying people are brain damaged.


Thanks for the hint you are right, wrong wording. But I kind of like old fashioned words.

Anyway, more seriously, let's discuss objectively about what makes this software worth 1,5k$. I am really interested in the discussion.

What do you see in this software that makes it so special and worth the money ? super duper EQ filters ? Even better stereo widening ? I personally like to keep my audio samples untouched.
Many products exist already on the market, many are free... and open source. Ok not so simple for mac, but is that the only selling point ?

Say you listen to PCM samples from a CD, quite typical example. What is this software doing to make the samples suddenly so fantastic ?

Not according to what I just paid for some software upgrades!

On a forum where people regularly drop some crazy coin on amps, DACS etc...I'm really surprised by the sour grapes tone of some of the posters here.
All the more so as almost no one has heard amarra.

Yeah, 1.5K is some serious money but it's not like it's tootally obscene or out of line with what folks are paying to hear good music.

Why not give it a fair try before claiming it to be overpriced?
It is a lot of money, but for all we know it may improve the sound just as much as if you spent the same amount on hardware (DAC, amplification, ...).

Although I don't know what is so special about this software I would think twice (more like ten) times before I would spend $1500 or more for a small piece of code. Especially because most of what the program does isn't all that special.

That said, I haven't heard it and it might very well the best thing since sliced bread, but even then, how long will it take before the code to achieve this supreme audio quality will be available as open source? I don't mind waiting for another year or 2 if that means I'll save another $1500. Being the first with such things always means you will have to shell out big time.

The gut reaction many are tossing out in this thread reminds me why I don't visit HF that much anymore.


that explains why they released it for mac, but why not for pc? As tiny as the mac userbase is in the overall picture, the pro-audio niche has to be even smaller. The PC by comparison I would imagine would be just as big if not bigger. Why not release on Win platform too?

Is its most valuable feature that it does bit-perfect?

So.. just so I'm understanding this properly... Amarra is basically a bit-perfect driver for the mac audio? That's all you're getting for $1,500?

There is more to it than that. I have yet to hear an equivalent PC-based system that sounds as good, and I am primarily PC-based. I just got a Mac Mini two weeks ago.

The experiments that I have done using WiFi devices, reclockers, Firewire and USB converters demonstrated to me that there are two components to Amarra:

1) jitter reduction of iTunes
2) avoidance of damaging code in Core Audio

I understand (1), but not (2).

Without Amarra, converters that are affected by jitter sound fairly bad using itunes, worse than the same converters used on a PC. With Amarra, they sound better than on a PC.

With the jitter basically reduced to inaudibility levels using reclockers and WiFi devices, Amarra still makes a difference. This is not jitter.

Amarra handles the data differently than Windows audio stack or Mac Core Audio. Format is different. Based on Sonic Studio software for pro audio recording studios.

Damn, you hit the nail on the head.

@leeperry: that's an interesting statement, can you provide some background? one would think the pro audio world would be concerned....

curious, especially as iTunes running under OS X on a Mac has been demonstrated empirically (ie not just by "I heard it" or "there have been shoot-outs" comments) to yied bit-perfect playback and output of source files at rates up through 24/192. see as one possibly interesting example the testing info on Kent Poon's design With Sound site Design w Sound » CAS 5: CD Ripping ; and as well his results confirming iTunes (QuickTime?) errors with hi-res files in Windows Design w Sound » iTunes 8.1.1.10 PC Problem.

@empiricalaudio: steve, as you understand /1/, would you be so kind to explain how iTunes (a file management program) creates jitter?

confused: isn't jitter a characteristic associated with timing discrepancies of data transmission in bus architectures; in the general case for audio as discussed in these and related threads -- and as explained in many of your postings on various fora -- these of interest are external to the computer, such as TOS/coax SPDIF, Firewire and USB -- the interfaces that reclocker products are intended to address.

also, how does this other software program (Amarra) likewise have an effect on external bus timing jitter?

or do you mean some other type of jitter?

specifically interested to understand your post above in light of buffering / data translation which takes place before data "exits the computer"
