I don't really compare them against each other. I know what I like when I hook them up w/ my headphones :)
The Cowon S9 has pretty good output power, it can make T1 sound too loud to even put on my ears when set to highest volume (although I never really pair these together, only tested a couple of times). That's why I haven't bought a portable amp until now. I just want to try how my iPhone/iPods pair w/ a portable amp. For now I quite like the combo.
