The DIY version means you can change the OP amps by yourself. so you can DIY the sound by yourself, also we may provide customize laser printing for the DIY version, and it will be limited edition. so this model should be call E12D. for the price, it is too early to decide it will be $101 or $199 because
the design has not finished. but for most poeple who buy the comercial version. the price will be reasonable.
Noted that FiiO's portable amps line up will includes 3 basic universal model, E6-E11-E12, with a special model which only support iPhone, before is E1, now we have a new model E02i, so E12 will be the eldest brother.
What about making a iphone/ipod dac?
