for some reason I did a couple of test to verify that E17 bypasses the S4 DAC via minimicro
or even USB OTG cable.
both cables are working for me as I was able to listen
thru Alpen's output jack. I had this thinking of doing some test since I found out that
volume rocker on the S4 is still working despite it was connected to E17.
So here's what I did. resample Eagles Hotel California 24/192 down to 24/96 via
dbpoweramp. PowerAmp was able to play this Hirez directly. When i try to connect the
Alpen on S4 it did lock and then hit play. The E17 display on top that it was still on 16/
44khz while on the S4 it did show 24/96khz. in short I didnt hear any difference at all. so
I did use USB Audio Recorder Pro and it did connect to the E17. Luckily as I hit the play
button E17 displayed 24/96khz which the USB Audio app shows as well. Only that time
I heard what was about to be heard. The bass slam is quite noticeable and so as the
soundstage. You could almost pinpoint their places and my HeirAudio 4.ai delivered all
the clarity of the entire song.
One more thing is when I was about to press the volume rocker in the S4 it did not
affect the volume at all, even at 0 level. all the volume is handled by the E17 as well as
connecting my plug to S4 audio jack I couldn't hear anything. See screenshot of the app
playing the 24/96khz flac file.
