Hey guys, this is my first post here. I've owned the E5 for about 4 months and have been using it with a pair of Koss Porta Pro and have recently got a pair of hifiman he-400i to get some better use of it. However I get an annoying hissing sound when it's plugged in via USB, it's the same when plugged in with the lightning cable to my iphone 5. Toslink works perfectly fine on my computer but I lose volume control :/. Is the problem the actual cables or is it the output on the iphone/computer? Any way to get the same volume control using the Toslink as USB? Would be very thankful for help.
I'm using my second E5 (returned the first one to Massdrop after it became defective after 6 months or so).
While I was trouble shooting the defective unit I tried several different USB cables (the one it comes with, Amazon Basics, etc.) On both the defective unit and new one I do hear the hiss. I only hear about 5% of the hiss when I plug in my IEMs via headphone jack directly to my Macbook Pro. The hiss remains constant even when I turn the volume on the DAC all the way off, or increase it significantly.
I suppose I always just thought this was standard when amplifying an output from a computer and I've never thought much of it since I don't notice it while audio is played. I also thought I had the same hiss on my previous FiiO DACs. I had never noticed before now that the hiss would remain constant regardless of volume.
I'm using a Macbook Pro and Noble Django IEMs.
If anyone knows why this is or has a solution, I'd be interested.
