ipod and dac?


Has anyone used an ipod or similar device with a high quality d/a converter? I love the idea of the convenience with the ipod and duplicating my cd collection, but I hate the idea of compressing the data and losing the sonic quality. I welcome any ideas on this topic as well as ideas relating to how to make the ipod and the like a high quality digital source. (Can you modify the recording rate to make the music quality better?) thx

OK, I'm getting ready to pull the trigger.

I guess I'll have to experiment with different compression schemes [uncompressed, better quality v. compressed, more songs] to determine what works best for me.

But I'm wondering, are you iPod users happy with the supplied Apple earphones or do you use something like the Grado SR60s I use at work?

Thanks.
I do not like the Apple supplied earphones. They sound okay...but do not rest comfortably in my ear. They might work for you though. For me, after a solid hour of listening, my ear hurts from the way they rest.
Gunbei, The supplied earbuds are good quality for their size and weight, but if you're used to Grados, you'll want to stick with them.
I use Sennheiser 580 precisions. Best thing to do is rip a CD using several different rates of compression and then one straight to the hard drive, uncompressed and see which is acceptable to you. For me, other than straight the the hard drive, uncompressed, the next best thing is to use AAC at 320 kbps. At that rate, using AAC, you can fit 400 CD's on a
40 Gig i-pod and it would be about the next best thing to uncompressed. It is an interesting experiment, though, to see what is
missing at different rates of compression.
Peter_S, do you mean that the Headphone sites have issues with the compressed audio quality, or the headphone amplification and output?

I would think that anybody who's a serious headphone listener would probably have something like a set of Grados and a Headroom headphone amp .. if a listener's used to that level of fidelity, I doubt that anything less is going to satisfy.
