The one labeled "USB" can either play music from your source DAP or charge your source DAP as per the setting of the switch next to the USB port.

You can charge your E18 while playing music from either your source DAC or line input.



I was answering someone else's post on here. I fully understand the functions and ports. Thanks though

Sobering and sad that James is going through all that.  If I were able to believe in prayers, he would be in mine. 

 

Here's hoping that James is able to rejoin us soon.

 

Edit: Just read Joe Blogg's update and, thankfully, James is fine.  Apparently, my non-prayers were answered even before they weren't said!

Sorry to hear about the news on the FiiO team, here's to a fast and full recovery for James.


Question on the E18: Is anyone else experiencing noisy pot? Mine makes a good amount of noise while adjusting the volume like a dirty pot.

Any news on the latest production models?  I have no DAP now and the SQ on the S4 is terrible!

You might check out Viper4Android while you wait, if you can root your phone. It's nice to have, both with and without the E18.

Are people using hi gain or low gain with the hd598, what are the sound differences? And is anyone using omega rom for their S4? Is there a problem with alias with i9505 on 4.3?

There is something seriously wrong with the s4, specifically its sample rate conversion. On the i9505 variant, I tried a 0-22050Hz sine sweep and recorded a strong alias going back down from 22050-0Hz. Imagine the havoc that plays with music... This is directly through the i9505's headphone out, the result going into the e18 may or may not be different.

The octa-core i9500 that nobody has may be different in this regard?

Any problems with Note 2 or Note 3?

Don't take this as an official statement, but I always use low gain unless I peg the volume knob with low gain.

You could listen to the sine sweep yourself and see if you hear a pure tone rising or the cross between the rising tone and the falling alias that I described? Would be interested in your results since I have a rooted i9505 on stock rom that's just lying around while I use a cheap Chinese clone unless and until I get this audio issue figured out rolleyes.gif

Isn't aliasing something that occurs when overloading an A/D converter? That's not being used in this case, it's more like D/A conversion being used on the phone or E18.

The HD598 has a 300ohm peak at 100hz, which means using my e11 on high gain +4.5dB makes it sound much better and balances it out. The e18 has +7.5 or +1.0db which may mean the gain might be too low or high.

Just a quick note. As mentioned in this this thread, my lg g2 also sounded bad when playing thru USB. A couple of days ago I received an ota update after checking for an update. Sound is now great. I'm running stock software VS98012B.
