Correction: E7 is planned for June / July release, but no solid date yet. It will be a small desktop DAC/AMP targeting as notebook internal soundcard replacement / upgrade.
Also, a silver color E5 is planned for release next month. Last but not least, an E1 model is also said to be under development, but no detail yet.
