CES ’08 – Venetian Room #30-236
Wadia Digital Debuts The iTransport
Enabling Full Resolution Digital Output From iPod® Players
-- iTransport Delivers Bit-Perfect Digital Audio
From Files Stored on All Currently Available iPod® Players --

LAS VEGAS, NV, January 7, 2008 – Wadia Digital, a high-end audio company dedicated to the development of digital audio technologies, is demonstrating the market’s first digital player dock to retrieve a direct digital signal from an iPod®. As a result, the audio signal remains pure and unadulterated, providing CD-quality resolutionfrom full-resolution file formats such as .WAV and .m4a (Apple® Lossless).

The iTransport (SRP: $349), which is certified Made for iPod®, turns any currently available iPod player into a high-end media server by providing a bit-perfect digital audio output to an audio/video system, bypassing the player’s internal D/A conversion and output stage. Subsequently, the audio signal remains clean and unadulterated throughout the path. The iTransport is compatible with all currently available (Q1 2008) iPod players, as well as iPhone® and iPod Touch® models.

“Until now, there has been no real bridge between the convenience of an iPod and the high-end audio listening experience,” commented John W. Schaffer, President, Wadia Digital, Inc. “The goal of making the player a true high-end media server has been hampered by the need to send the digital signal through a portable player’s D/A converter rather than that of a high performance audio system.

“Instead, we designed iTransport to bypass the player’s converter and output stage altogether. When used with an iTransport, the iPod becomes a digital music source equal to some of the finest sounding transports in the high-end audio market.”

Along with turning an iPod into a high-performance audio server, iTransport is one of the first such products to access video content stored on currently available iPods. Similar to the audio section, the video signal is made available via high performance component outputs that provide up to DVD-quality video.

The iTransport measures 2” x 8” x 8” (H/W/D), making it an easy addition to most racks and entertainment centers. Wadia incorporates a bit-perfect S/PDIF digital audio output and high-resolution component digital video output, as well as analog audio and video outputs for
easy connection with most audio/video systems. iPod players are charged while in the dock, and can be operated via Apple’s standard IR remote control. (Not included with iTransport.)

Wadia Digital’s iTransport will ship in February 2008, and will be available at select high-end audio specialists and the Wadia Digital web site – Wadia Home Page.

iPod is a registered trademark of Apple Computer. This product has been designed specifically to work with iPod
and has been certified by the developer to meet Apple performance standards.



Steve I know you're preparing for CES yourself but whats your opinion on this?  While its certainly much cheaper than the MSB Link, it may still be a rather small market.  I know you had dropped hints ofa digital out on the ipod of your own design; would you scrap that idea in favor of modding this (i can just imagine it feeding a formula one w/ pace car mmmm :) ) or do you plan to pursue that course of action.? (I believe there is more demand among both professionals and hobbyists for a portable solution.)

Very interesting indeed.  At this price, it may make sense just to purchase one and add a Pace-Car to it etc..

On the other hand, if it is this easy to extract the digital out from an iPod, then I may have to do my own interface.  It would be really nice to add a coaxial clock input such as the ones I add to Sonos, Squeezebox and Olive to the new iPod.  This way it would be synchronous to the Pace-Car.

I guess I'll have to buy one and dissect it.

As I think more about it, it may not be necessary to mod the Wadia.  If no mods to the iPod are needed for it to work, than that would imply that the Q1 2008 ipods will have digital out on their dock pin outs  :drool:.  I could be wrong but couldn't this just be a super-expensive dock in a fancy chassis? A straight i2s output would be fantastic for feeding either a home system or the new wave of i2susb dac/portable headamp products hitting the markets recently.

Without an updated or specially modded iPod I'm not sure how they could be getting digital out to the dock.  The dock pinout doesn't have i2s or anything similar brought out that I can see.  It's USB and Firewire, so maybe there is some software solution that can redirect raw file reads to one of those serial ports that they pick up but that seems really tricky in such a proprietary platform.  The pix of the rear connector at CES only show a connection of analog R/L outputs, so I'm still skeptical.  Should be interesting indeed.

tapping the digital out from the IPOD to an outboard DAC is not entirely new, eg. this $150 'mini system' takes the digital out from the IPOD to its own DAC and built in tripath amp.  This is a few years old.. and costs much less than the Wadia.

From what I understand, the digital signal Wadia is extracting is available readily through the dock connector. The trouble has been Apple allowing access to it (via software encryption of some type)...they have allowed a few companies over the years access to it...there is some mobile audio solutions that use it...and the above mentioned piece....but it hasnt been widely publicized. Now, apparently Apple has given rights to this process to Wadia...and no doubt other high end manufacturers will notice and probably develop similar devices. Its interesting to say the least and knowing Wadia, it will be a great piece of equipment for what it does. :)

Did they give Krell authorization too?

If Wadia is and Krell is, then Theta Digital is next  :wink: Goodbye CD.

At $349, it probably is not interesting for me to do my own docking station to extract S/PDIF.  However, the clock in the iPod is the real problem.  If only they had a way to get the right clock into the iPod.  Then I could master clock it from the Pace-Car.  I know the Video iPod that I dissected had only 12MHz clock inside, which does not help.

I think the thing to do with this is what I do with the AirPort Express: Add a type 2 Pace-Car to it to reduce jitter.  It would have to be tuned to the iPod, so the customer would have to send my their iPod for a short time. 

This is what I'm planning to do.  I'll buy the Wadia docking station, connect a Pace-Car and then tune the Pace-Car to my iPod.

I exhibited the AirPort Express driven through a tuned Pace-Car at THE Show last week and it is terrific.  Same audio quality as a Squeezebox, Sonos or Olive through the Pace-Car.

No, this uses the balanced analog outputs.

I believe this uses A/D and D/A.  I find no mention that it uses native digital output from the iPod.  I believe only Wadia has this.

I recently stumbled on a bunch of internet chatter about the Wadia itransport putting out a LOT of jitter. It may have been a competitor that started much of this talk but it still has me thinking of improving the already great sounding itransport.

I would think the Pace-car would work or be easily made to work. What's the latest thinking?

The clock in the iPod is used and then the PCM2705 is used in the iTransport.  Both less than optimum for jitter.

Yes, Pace-Car 2 (the new one), can be used with the iTransport.  It must be used in the "tuned" mode, so I must have the Wadia here for a day or two to tune the Pace-Car 2 with it.  In this mode, I can only use the Superclock4.

The Pace-Car 2 will effectively reduce the jitter from the iTransport to extremely low levels
