I agree with this topic. I got the KSC75s this weekend, and just now I got my friends 1g shuffle (I sold my old one to my mother to get enough money for the new 3g nano). I like the 3g nano, but after listening through my mom's shuffle, the SQ change was amazing.
Now that I have my friends shuffle, I can finally go back to simple, screenless playing with amazing SQ. My 8GB 3g nano has just changed into my new movie/TV show player, and my 512 shuffle will once again be at the top of the list.
After modding the KSC75s, they do sound amazing, and I need to rewire mine sometime. I am only a high school student, but sadly it seems I am going the way of many here. My wallet is already feeling a little pain.
Well, time to go test my new shuffle (the songs just finished being added).
