All internal processing is also done at 32 bits bit depth. However, all current targets truncate to 16 bits at the output. This can be fixed if someone cares enough about it to do some programming, but the DACs in current targets really aren't good enough for this to make much sense.

anybody please tell me is this the reason why i always feel better with rockbox sound quality(an old topic talking about this.. http://forums.rockbox.org/index.php?topic=6139.0 )
sorry for off topic...

soap:
Is there any reason to believe this device does anything other than use the iPod as a USB hard drive and get track info from the iPod database file?
I, personally, find this easier to believe than a super-secret way to stream high-bitrate audio through the USB port.

Its not.
dreamlayers:
I looked at some info online just for amusement purposes. I wouldn't actually want to get any of those things or develop support for them; I just find it amusing to see how "audiophile" products get hyped and marketed using pseudoscience. In some cases, I'd find it more respectable if they asked you to send a lot of money and promised to in return bless your music so it sounds better. At least then they'd make it clear that they're not making scientific claims. Anyways...
The Wadia iTransport can apparently get digital data from the iPod Classic and the newer nanos. I suppose they are able to output SPDIF and it's just an overpriced dock. For other iPods (the ones supported by Rockbox), it goes into "extended interface mode" where the "click wheel interface" is not available. That means they haven't been able to get digital audio out from those iPods, and so they just use the iPod as a USB mass storage device. In this mode you get a horrid simplistic interface: you can either continue playing what you were playing via the iPod's interface or you can play everything in all tracks mode. Here's a PDF FAQ and PDF manual. Here's a page with some low res pics of the insides, and some ridiculous mods. Oh, and the thing is not HIRES: I read that it always outputs 16 bit and 44.1 kHz!
If you want digital out from earlier iPods, you need another overpriced gadget, the MSB iLink. The iPod needs to be modded for that. I guess they connect I2S to dock pins.
The only reasonable related task that I can think of is support for streaming audio to a USB audio device. That would allow both reasonable use, like streaming to USB wireless headphones, and unreasonable use, like streaming to a USB audio device which is built from vacuum tubes instead of solid state electronics.

First, let me state that I'm not trying to invade your space with an audiophile nose-in-the-air attitude. $1500 is certainly not excessive with respect to a music server (with a DAC and headphone amp (which is what the Wadia system actually is.) What it is not, is a glorified ipod doc with a Wadia nameplate. And the Wadia doc is not $1500 ...it's $379 ...the matching DAC and built-in Ray Samuels headphone amp is $1500.
Secondly, commenting on the sound of a system or device without hearing that device elicits very little in the way of constructive criticism. Quite simply, the Wadia/ipod combination replaces a fairly high-end CD player in its functionality and sound quality. If you do get the chance to listen to the Wadia tapped into a decent sound system, it may well change your opinion of both what is possible on the ipod and the need for CD player whatsoever. It's that good.
Taking it to 24/96 is simply the next logical step; hence my questions here. That would allow DVD-A and vinyl ripping. With 100's of LPs this is not a silly fascination, but rather an attempt to get high-end sound on a portable device.
Again, I'm sorry if I ruffled a few feathers ... I'm simply questing for the best sound possible, as I know the capabilities of portable music are just beginning to be realized with devices such as the Wadia, the iMod and the various headphone amps that are becoming quite popular. - Lorne
