I don't want to brag because I am offering it for sale.
But for sake of comparison, Steaxauce owns both the imod and the Kenwood HD30GB9 and he prefers the HD30GB9 over the imod. I haven't heard the imod, but among all the mp3 players I have tried, the kenwood's HD30GB9 comes on top.
According to Steaxauce, he prefers the kenwood over the imod mainly for its simplicity; not necessary it will sound better to you. Different strokes for different folks.
He offered to ship his imod to me so I can do a comparison as well but we are both very busy these days.
What is hot about the HD30GB9 is that it sounds good.
To be objective, it has a very good built-in digital pre/amp, so you won't really need to buy a portable amp, unless you need to drive hungry headphones like HD650. Its build quality is excellent and the interface and screen are the best I have seen. You can drag and drop (Folder browsing) or use the ID3 tag database (Artist, Genre, Album, etc.) Its equalizer doesn't amplify the frequency like other equalizers I have tried in other mp3 players, however, it alters the frequency, which offers cleaner signal. It has a very good headphone-out. And last, it is gapless.
It goes for $504 shipped from pricejapan or $511 from audiocubes to the states.
