ipod and dac?

Well said Johnmcelfresh.

However, I think we are underrating the iPod as a critical playback source. I have heard much worse. I have it feeding into my system via the Monster cable (which is the best available for the iPod) and it is pretty close to my standard cd playback. Again, I don't think it can compete with my turntable, but then again, I don't even use my regular cd player much anymore for "critical" listening.

If you're afraid of fragmentation on the iPOD, just copy all the files onto your desktop computer, wipe the iPOD clean and copy the stuff back to the now empty iPOD. Then everything will be stored in nice continuous chunks.

Any idea which filesystem iPOD uses? Microsoft (as usual) did a pretty bad job in this area. Both FAT and NTFS are very prone to fragmentation, but maybe Apple did a better job here...

Gunbei, you need to take into account how most people actually use their iPods. To get music into the iPod you need a computer that already has the ripped CDs. I use iTunes and the computer stored music is organized into various playlist (by artists, genre, favorite tunes, etc). When I want to transfer music to the iPod I typically select a group of playlists from the computer and wholesale replace those existing on the iPod. A month could go by before I alter the iPod again. Effectively I'm swapping 28Gb (the actual storage capacity of my 30Gb model) of data at a time. It takes 15-20 minutes for the entire process. So even though files may be written and rewritten over and over fragmentation just doesn't become a practical issue.

Thanks for sharing Onhwy61. I guess the next step is figuring out what kind of soundcard to get that has digital outs. Since I have a laptop, I'll have to find either a USB card or a pcmia card. In the limited research I've done, it seems USB cards suffer a little sonically.

Looking around the web, I've been seeing professional systems from Digidesign, tascam and others that are geared to digital multitrack recording with Pro Tools. They feature a/d, d/a converters and de-jitter devices, and come with plenty of analog and digital in/outs. Digidesign, in particular, has a unit that looks pretty good, and at about $450 on e-bay, comes with Pro Tools. Since I'm a musician, that would be a FUN accessory.

Any experience, thoughts on these recording-based systems as a way to get a digital stream out of my laptop?

Thanks guys for putting the proper perspective on everything. Like anything I guess, it all comes down to smart usage and good file management.

Onhwy61, using your scheme of mass copying and deleting, fragmentation should be quite minimal. And, if it does happen to occur, Stefh42's advice oughta clear things up.

One thing I will avoid though, is the practice of combining music files and high traffic data files on the same iPod. I see some people doing this, and this is an instance where fragmentation could easily rear its fractured head.

Thanks again!
