i had tried teclast t-51, it's the same with s:flo2. to me, they sound much better than cowon s9 WHEN you are using line out + decent amp.

there is one major turn-off for me, though..this thing does not have bass..the deep bass is like cut-off, none, diminished, gone!

but i heard when you upgrade the firmware to the newest version, this problem is almost gone..still there is some cut-off in the bass area, but better than before..

BUT..if you prefer simple portable music on the go..you cannot go wrong with any cowon models..
