I had an interesting experience when I first got my iPod. As I said, I didn't have iTunes on a PC at the time (slow dial-up at home and no admin privileges for office computer). A friend loaded up some stuff she thought I would like from her own collection.
It sounded, well not horrible, but uninvolving and two-dimensional. I thought, oh dear, that was a waste of money wasn't it.
However, I was trying to learn a piece of music at the time, so I showed up with a CD of the Brahms German Requiem and asked her to put it on the iPod for me, which she did. I was only thinking of it as a learning tool.
I was blown away. I couldn't take the earphones out of my ears. The difference was astonishing.
When I asked my friend about this, she came up with some complete BS about how her files had been copied and recopied over several computers, so they must have degraded. Well, even I know better than that. We're not talking about magnetic tape here. I can only imagine that he own files were at a higher compression, and had lost that je ne sais quoi.
I agree, once I plug the iPod into the Linn Majik amplifier and play it through the Linn Toukan speakers, it's not quite the same thing. But using the standard iTunes settings to copy a CD, then playing it through the earphones, it's definitely "good enough".
Incidentally, I noticed something else interesting. One day I was absolutely compelled to listen to the Berlioz Te Deum, which I didn't have a CD of (just a cassette tape which some day I must convert). So I went to the iStore and bought a recording of it, while I was at work (yes, I did torture these admin privileges out of IT in the end). I was so keen to listen that I plugged the iPod's earphones into the audio jack of the computer and listened to the beginning while it was still downloading.
I didn't much care for it. I wondered again about compression, or if I'd just chosen a poorly engineered recording. However, I waited till it had downloaded, changed the earphones to the iPod itself, and listened again. It was great. After some discussion on another forum, the opinion was that my office computer has a poor sound card. Just shows again that the iPod is well engineered to give a very acceptable sound in the context it's supposed to be used in.
I just wish iTunes was about 200% more intuitive though, and track naming was rational and consistent.
