I am ready for the E12,
my only concern being
It has narrow sound-stage?
and its 11 hour battery life [not a big issue]
I am just bugged by O2 because many headfiers seem to praise it.
I also read 200$ amp shootout article at inearmatters,
Clieos gave O2 1st rank and stated O2 as "reference amp"
"E12 Probably best pair with full size headphone that is either wide in sound-stage or more laid back in nature"
"but lacks the best transparency and sound-stage"
"The narrower width and depth cause the overall presentation to push forwarded, giving an impression of warmth and energitic sound with a rather musical vocal"
"O2 is the reference amp of the whole shootout and offers the best SQ subjectively and objectively. It has the best blend of everything, as far as sound being the only concern"
and that is the only article available for E12 VS O2
If anybody having both of these please put a word on it.
That bit about the E12 having a narrow soundstage is a load of BS. The crosstalk is better than 70dB so there isn't any crosstalk to narrow the soundstage, just gossip.
