What do you mean by, "the converter up there?"

Is that an iPod Classic or iPod Touch 5G? If it;s a Class, make sure that it does USB Audio, the Touch 5G definitely does as I use one.

Don't know what you mean by "power."

The E18 DAC does not draw power from the USB source and I find that it does not need a powered USB HUB,

My desktop DAC does draw significant power and requires a powered USB Hub.

Without a powered USB Hub:

  • My Verizon Samsung Galaxy S3 burns out as in self destructs and requires replacement.
  • My iPod Touch 5G pops up a message about power requirements and refuses to operate unless a powered USB Hub is introduced in the connection.

I have also used by GS3 with a split OTG cable powered by a USB wall wart. If one uses a Hub that will pass through power from the phone if the Hub's power source is disconnected the phone will fry. Other phones do not seem to have this problem, Caveat Emptor.

I'm using the e18 as a dac, and amp, and a power supply for my ipod touch 5g. The converter I was referring to was the one I posted about earlier (usb male to micro usb).

The fiio e18 has 2 micro usb ports, one for power, one for dac/amp capabilities. Plugging ipod -> cck -> usb to micro -> into dac/amp port shouldn't draw any power from an idevice. To charge the idevice from e18, all I do is flip the switch to charge.

Is any part of this incorrect?

Sounds like you're ready to rumble. I believe you are using the converter at the end of the CCK cable to connect to the E18. Good idea.

Alright cool, I had to do some research (aka watching youtube videos) to figure out there were 2 ports. The Usb to micro usb ships in 10-20days LOL. So I'm not in any particular rush to get the e18 anymore. I'll proably order it in a week though.

While you wait, the Touch 5G should sound plenty good as long as your headphone/IEM's are not power hungry. As I say, the DAC and Amp in the Touch 5G are surprisingly good. I look forward to reading your comparison of the Touch 5G alone vs. with the E18. Remember to carefully match volumes when comparing as the FR of human beings changes with volume.

Right, the main reason is for my desktop of course though, because my onboard audio is awful and there's terrible crackling/hissing sounds.

Nice write up, thanks!

Also, how low is the noise floor? I used the Fiio E07k with my Triple Fi 10s and there was audible hissing, (40db) not so bad in noisy environments, but when it was quiet, it was fairly annoying.

 

I'm getting T-Peos H-300 here soon, and they're a little less sensitive, so I'm hoping the e18 might even have a lower noise floor on top of that, and it'll be much quieter,

Take a look at FiiO's website, the publish SNR specs on their site.

Also, how low is the noise floor?

In real world usage as a stand alone amp, it's floor noise is very quiet on my iem ue900, and their extremely sensitive.

However in use as a DAC and amp an audible noise is there is some sort of tone, the noise doesn't get louder with volume increase, or high gain selected. The tone isn't very bad or noticeable in usage, and you have to concentrate to hear it.
But if you switch bass boost on the tone is terrible, which makes bass boost not usable with sensitive iem's.

I have been in touch with fiio and they are aware of this problem, and unfortunately this isn't in the specs as it should be.
On that note I love this thing and would not return it, with usb audio pro driving this, the baldur mark3 and the ue900 I think I'm in audio heaven.

If I want bass, I just use an eq. So that's fine.

Problem I have found there is the best sounding player on Android usb audio pro has no eq or any form of bass boost, until that's fixed, the bass switch would have been great.

haha. .. In a way I wanted to send it back, I really wanted to, but then I plugged the gallaxy s4 in and after 5 songs I was excusing this problem and plugged it back in.

The e18 had shown me how good audio can sound, and there's no going back, it's micro detail is revealing sounds I haven't heard before in songs I thought I new.
You won't regret the purchase.😎
