Dear Feiao,   Thank you for all available Fiio products, I am using them since very early time. I would like to buy the E11, but I see that you will update it with new jacks and battery in year 2013. Can you please specify when? I almost bought it on mp4nation.net, but I would like to have...

Please, can you adjust GAIN in menu? And can you turn off BASSBOOST? I don´t think SRS Trubass, I mean BASSBOOST from Teclast...Thanks

Now I am using Cube C30 and ICOO IX35, so both ST3770. I am very excited about Teclast X19HD, as it has HW BassBoost. Can someone tell me if the BassBoos can be turned off and if you can set gain in the menu? Thanks :) If so, I will buy one for me...

I am using E5 and E3 with my headphones, even when playing music in car Pioneer stereo makes very difference in quality and sound. So I really hope final E11 come out soon :) It is not only about amplifying sound/music, but it makes the sound much more enjoyable... The best it would be if there...
