Yes, you are right , our E10 will cut off the music about 0.7mS to solve the phase shift distortion of the WM8740 with the TE7022 USB receiver.
and it can not solve by any firmware or fixed it by hardware. but our E17 have not such problem because the structure is different, the digital signal
will go through wm8804 so we don't need to reset the WM8740 each time when there are new signal to make sure it work perfect.
If you have any other question, please feel free to contact us!

Subject:E10 cutting off beginning of audio stream
Hello, I placed an order for an E10 in September and received it from
MP4Nation at the end of November. I am very pleased with the quality
of the DAC except for one issue: the beginning of any new audio stream
that opens and is outputted to the E10 is cut off. The amount of the
waveform that is cut off is small, but the E10 is definitely not
outputting streams entirely correctly. I use my computer for audio
editing and this problem is particularly frustrating for this
application. I have a PC with Linux and a Macintosh, both using the
default USB audio drivers, and have experienced the problem on both
computers. I asked about the problem on Head-Fi (
http://www.head-fi.org/t/575084/impression-fiio-e10/705#post_8059306 )
to see if it was just my setup or if other E10's exhibit this behavior
and several other owners have confirmed the issue.
Is this a problem that can be fixed with a software or firmware update
for the device, or is it a flaw of its design and unchangeable? If it
is not fixable for the E10, is a future FiiO DAC going to address the
problem? Since I purchased the E10 for audio editing and it is
currently not suitable for this, I would be interested in returning
the product if possible.
Thank you for assisting me.

It's a shame that a company would produce such an otherwise excellent product with a flaw like this.
