Apartment system iPod to headphones


I am now renting an apartment and rather than duplicate my home systems I will instead go just with headphones. I have half my music on a classic 120 G iPod and will buy another for the other half. (I want to travel with my music as well). My music is stored in Apple Lossless format on the iPod. I already know what I want for a headphone rig. I am willing to spend good money on a device to get the bits and a DAC to send analog to the headamp. I want the best method to extract the music from the iPod and get it to my headphone amp. How can I extract the exact bits from the iPod in a digital stream and preserve the fidelity? What have you tried that works for you? I will not have a computer, just the iPod that travels with me to the apartment several times a month. Thanks.

Teac has a digital docking station that has received some good reviews (never heard one myself). Looks like it is the DS-H01. Built in DAC. May be good for what you are looking for.

I also believe that Wadia builds something close to this.

What do you plan on using for your headphones/amp?
Thanks. Right now I have a Bottlehead Crack that I built and an ASL Antique Sound Lab MGHead. both are tubed amplifiers and I prefer tubes with my Senn HD600. I am open to other options but don't want to spend too much on this small application. The Pure i-20 looks good if it's still available. Esp for $100. That leaves me room for another set of cans and amp. I have considered the Schiit amps with their entry level at $349 for a tubed amp.
I have the Purei20 and also the Wadia i170 docks. Big difference in cost, no difference in sound that I can hear. As long as you get a dock that bypasses the iPods internal dac you should be good to go.
