OK.......
Very insight information i think.....
Owning C200 for a couple of years now (but never had the chance to hear C10).. just wanted to add a few things there...
Firstly "the constant seize-ups" seems to have dissapeared from C200 as well using the LO with E12A Fiio amp....Have noticed that E12a does not affect at all the sound characteristics of C200 in contrast promotes in a good way the original sound signature just adding a bit of an extra weight in sub bass region,emphasazing a bit on the low end which is simply fantastic result...
Secondly, the dac chip which is used in C200 the sabre ESS9018K2M is famous for its transparency and the airy sound that provides, thus resulting in more space and air between instruments and a more open sound which in its way benefits the whole soundstage preception.....Maybe i guess that C10 being more congested and not difused sounding results in a more coherent sounding source with more accurate definition of its instrument....The dac chip which is used on C10 is the same that Fiio has used on X3ii & X5ii (both very precise accurate sounding daps highly appreciated from the audio community as well)
Finally having heard a bounch of daps lately... i can confirm that in terms of clarity and brightness C200 outperforms lots of them...
If anyone prefers a bright,midforwarded,open wide sound, with extra emphasis on the vocal performance then C200 is TOTALLY RECOMMENDED...
