Amarra for iTunes at RMAF...

I experimented with Amarra.

Macbook with 4gb Ram and SSD HD.

I returned the ilok for a refund.

I'll live with iTunes and a PWT until Audiofile-Engineering comes out with their playback software.

Kana813, you need to use a suitable way of getting the bits out of the Macbook or else using Amarra is pointless. An asynchronous USB Dac, an Empirical Audio interface, a Lynx card etc. If you don't then you won't hear any of the benefit of using Amarra. The jittery output will render it moot.

Antipodes_audio- the output of my Macbook was reclocked via an upgraded Genesis Digital Lens, so jitter wasn't an issue. I also tried an asynchronous USB to SPDIF converter
before I returned the itok.

IMO, the difference between Amarra and iTunes isn't anywhere near the difference between DACs.

Plus, for less than the discounted cost of the full version
of Amarra, I can get the new Auraliti Player.

What was the asynchronous USB to SPDIF convertor Kana813? I am not aware of any other than the Wavelength Wavelink. There is a Musiland but on examining the board it is clear that it cannot be asynchronous, despite the claims. I would be very keen on getting one if there truly is one on the market. The Wavelength one isn't available yet I don't think.

I don't share your faith in the Genesis Digital lens rendering jitter not to be an issue, it is just a PLL device, but if you are right that it does then of course Amarra would make no difference, and you could use any old PC or Mac you like with any old crappy cable you like to feed it.

Antipodes_audio-

The asynchronous USB to SPDIF convertor was an ART Legato. It uses Streamlength firmware.

I suggest you read the Stereophile review: http://stereophile.com/digitalprocessors/824/
of the Genesis Digital Lens before saying "it is just a PLL device." I'll bet you've never heard one.

PSAudio will be coming out with a new digital lens that will handle hirez data.
