Is E17 compatible with USB audio output on Synology NAS? Anyone tried it?
What was the problem with it and the Dell?
That model always had grounding issues, so who knows what the root problem was, but any attempt to play music over USB was met with a layer of static over the intended sound. Tested it in Windows 7, 8, and Ubuntu, no change.
Gotcha. Glad the new laptop works better.
If I am correct, Chris is saying that since the E17 doesn't sport as much power as E09K (designed to work for 600ohms impedance headphones), the E17 is meant for headphones with low to medium amount of impedance (let's say "medium" is around 300 ohms) with mid to high sensitivity. Sensitivity & impedance = rough idea of efficiency.
And by efficiency it's sound level per unit of power.
You got all that basically correct. Someone should buy you a drink!
I'll try to expand.............with a short, oversimplified answer:
The E17 outputs less voltage so is less suitable for high impedance headphones
and outputs less current and less power so would be more suitable for high efficiency 'phones.
E17 should be able to drive any Grado, for example.
Obviously the E09K outputs more voltage so better for high impedance 'phones
and outputs more current and power so would be more suitable for lower efficiency 'phones.
So if you had a low impedance, low efficiency 'phone, you may need the E09K.
The Audeze LCD-2 guys would want the E09K. In actual practice, anyone with enough $$$ for the LCD-2 would buy a much more $$$ headphone amp anyway.
Yes, efficiency is the sound level per unit of power: for example: 96 dB SPL @ 1 milliWatt
Sensitivity is sound output per unit of Voltage, for example: 105 dB SPL @ 1 Volt
Having said all that, I use the E09K + E17 for my Q701s because I like the sound of that system even though the E17 + Q701 alone is loud enough for me.
Here's your drink by the way:
has anyone had a problem with their fiio e17 only playing music out of one side of their earphone/headphone? I have to manually adjust it for a few mins to be able to hear both channels
tried my headphones in other things such as my phone and pc and it works fine.
So, what headphones won't the E17 drive to a satisfying degree? I'm guessing Orthos but any others?
edit: just saw above, high impedance phones.
Not necessarily, one chap has been driving a set of HD800's (300 ohms) with great results apparently. I hope to test mine out in a week or so's time...
Just makes me lust for HD800s even more!
