One of our user sent mail to us, he told us that he discovered that the NOKIA N8 can output the usb digital music signal , and
can be decoded by our E7. below is the thread
We will do some test by ourself, but you can also have a try by yourself if you have below phone which support USB OTG
NOKIA C6-01, C3, C7-00, E7-00, X3, N8, N9.
Of course you need a USB cable and a NOKIA USB CABLE (CA-157)
I think it is a good option to people who want best SQ on the way. and we may design a short usb cable which can
connect NOKIA cell phone to any portable USB dac , like our E7.
