With usb player pro I can regulaze the volune of the amplifier lower and therefore reduce the hiss significantly with my dn 2000j! Maybe rooting the phone and installing some new kernel gives me more access to the volume control?
Just tested the sfb plugged via otg into my samsung s6. With the sine everything alright but playing with my sensitive iem, the dunu2000j, there is notable hiss in quiet environments.. more than playing directly through the s6 jack.... I bought the dfb in my hope to get a black background with my iem.
Oh wow now it has some reserves! Sound opened up quite nicely but to need an app for this was not intended...money and some extra hassle... i will try with movies later if the volume control of the black works there...
been listening for an hour to the sine.
Very spacious for an on ear, i usually prefer brighter iems/headphones but I can't fault their treble much.
Detail/resolution seems to be on a high level. I have/ had high end iems like ie800 and dn2000j and I don't feel like the sine lack far behind in that department.
How is the bass and treble of the oppo pm3 in comparison?
This is a audiophiles portable dream device. I am using very sensititve to hiss iems ( ckw1000anv) and always encountered hiss on the note 2 / 3 and other galaxies, sonies and htc's. Only the iphone 4 till 5's had a total black background. The newest generation of iphones has notable hiss and high output impedance which won't be good for highend iems which mostly consist of multi ba and hybrid setups.
The s6 with its total black background and output impedance of 0,7 ohm...
