Recently , there are some user sent email to us, ask about the firmware of E7, so I will like to reply in here!
1, The firmware of E7 can be upgraded by a special kits! but it can not upgraded by USB, means that you need to send back to us or to our distributor to upgrade the firmware!
2, It is over 6 months since E7 launched market! and we do upgrade some features of E7, but all is small change, and onthing about the SQ!
3, We will recall E7 if there are any defect or any bug that affect the usage or SQ! as you all know , there are so many thread and replies in Head-Fi and other forum, but so far there are
not any firm defect！ and E7 had been proved to be a reliable and qualified USB DAC/AMP!
4, To our all products, we will keep improve the quality and features! but it is not means it is a upgrade in quality! it is something about better, not good and bad!
Hope all you can understand us! and we will keep improve our products and service!
