Let's not start a war here.
The clip+ is a legend because it s not crap, when sold at crap price. there are a few cult products like that. I got the koss porta pro that comes to my mind.
and i wouldn't want to know only the sound on that combo as legendary as they get.
for the money you can't get better, that is true. it doesn't mean that you can't get better nor that you need to. you just need to know if you enjoy it.
we all like a special kind of sound even if we crave for more details more space more everything, we usually enjoy it when it can get the same flavor we knew before(that is human nature). it s hard for a bass fanatic to enjoy flat and vice versa. but as most people without sound culture feel of quality when they get big bass, people naturally tend to like warmer sound.
in that respect i believe we can recommend a cowon to almost everybody after a clip+ .
but then you must survive the UI of cowon. (i just made a long useless review on the iaudio i10 whining about it)
i would push apple users to sony because they won't mind all the boring proprietary stuff after apple but wouldn't like cowon UI. (i know cowon usb sucks too)
and i would push almost everybody else looking for sound and only for sound without a fortune to cowon.
so OP i m with h20fidelity here (with more love for the clip+), you would feel the sound upgrade on a cowon, and would probably like it.
