iPod to DAC Connection


I was disappointed that the fourth generation iPod announced this week did not have a digital output so that it could be hooked up to an DAC. I think it could provide near audiophile caliber output if you used the best AIFF or Apple Loseless processing options and a digital output. Now, I'm wondering if it is possible to have a digital output for it by somehow hooking up a cable to the iPod itself or the dock that would be Firewire or USB 2.0 at the iPod/dock end and S/PDIF at the other end to plug into a DAC. Anyone know if this is possible? Does such a cable exist, or maybe the digital bits coming out of a Firewire output are different from those going through a coaxial data cable? Any insights would be appreciated.

I think they should put sporty tubes on the 'pod as well - of course you are walking around and... OW! THAT'S HOT!
PocketDock combo is a device you attach to your iPod that gives it a firewire and USB out. With it, you can connect to a USB DAC. There are a few high-end USB dacs on the market, but I can't think of the names. Here's the url to the product page...

If you go down the SendStation route, you should take a look at the WaveTerminal U24 which is a pro-audio USB device.

Provides Toslink, S/PDIF and 1/4" RCA outs and requires no power (gets it from the USB). Have one between my Mac and a Monarchy DIP/Channel Islands Audio DAC and it sounds very, very good - especially for $200 at B&H!

I'm using the Apogee USB Mini-Dac for a computer based system. The sound is excellent!
It is not clear from the promo whether the PocketDock will let you plug an ipod into a USB DAC. Correct me if I am mistaken, but it seems like it is just meant to let your ipod interface with your computer -- similar to the accessories that already come with the ipod.
