So since I'm waiting for the FIIO Q5 to hit the market, I decided to swap out the opamp in my FIIO E12A.  Basically made a poor man "FIIO E12A DIY" for IEM's.  Desoldering the Muses02 was a bit of challenge due to the soft legs.   Installed the AD797 that came with the E12DIY kit.  Sounds really nice.

I'm on a trip all day today so I grabbed my X5ii, Westone UM Pro30's and E12a as I headed out the door. En route I discovered that I accidentally forgot to shut off the E12a from my last listening session, and yup it's drained. Oh well, no problem the X5ii has its own built in amp. I have always tethered the E12a to the X5ii, preferring the E12a amp sound. Today I'm listening through the X5ii amp, although good sounding I personally miss the E12a's clearer and more detailed sound. I find the E12a much more dynamic sounding. My UMPro30's sound warm (verging on muddy) straight out of the X5ii. I'm glad I decided to keep the E12a after I purchased the X5ii!

When I stacked the e12a to the new X1 I was pleasantly impressed with how much it improved the sound. So recently I got to review the DX80 and wanted to see how the e12a will improve it. All I can say is HOLY Damn.. The e12a completely ruins its sound. Such a narrow sound stage in comparison. So weird

This is how it felt when using E12A with x5ii. 
 
With x5, e12a made the sound incredibly better. 
 
with x5ii, it did not. 
 
Seems the psychoacoustics are strong with this Amp, and the synnergy is extraordinairy important when pairing it with a DAC.

That's unfortunate. Myself, I much prefer he X5ii with the E12a.

Dont know about you guys, but the moment i plugged E12a to X3ii its a conbo permanently,that happened two months ago and i was totally impressed with E12A's ability to enhance X3ii's sound,soundstage and separation got immediatelly better,and i even managed to hear details in most flac recordings i wasnt able to obtain earlier.Totally black background environment with the majority of my iems(fidue A73,dunu DN2000j,Fiio EX1,RHA 750,havent tried though with full sized headphones,but i am absolutely satisfyed with any iem performance on E12A...

Hi.
I was thinking of buying the FiiO E12A for using it as a desktop amp for a pair of  Beyerdynamic DT990 Pro 250Ohm. Do you think this is ok? Will it be enough power for the headphones? And will it be ok to leave the amp always connected to the usb power source?

 

[blazinblazin]

Not sure but A5 will be a better choice

Apologies if this is posted in the wrong place, perhaps you could point me in the right direction.  I've been pairing my e12a with an X5ii to great effect this past year or so.  I happened to let the e12a go completely flat (zero battery) and now it won't charge at all, all I get is a rapidly blinking red light.
 
I've tried different cables, and charging locations but to the same effect.  Pressing reset also does nothing.  Hoping to not have to buy a new one as this one is only about 20 months old.  Any ideas anyone?  Thanks.

A few thoughts :

- My E12 does the same thing if not enough charging power from a laptop USB so try a mains power plug adapter to USB instead.
- Rechargeable batteries might struggle to get going again ; either you have to re-try several times or accept the battery is dead... Not sure if the battery is replaceable but the E12 apparently uses a Samsung S3 so you might be able to get an equivalent replacement for the E12a.
- 20months while not old is past any budget electronic 12 month guarantee... It may be worth investigating a worthy replacement such as the FiiO A5?

Hi, perseffect
If you keep charging the E12A, can other functions work normally?

 

[perseffect]

Thanks for the responses.  I cannot get it to work even when plugged into mains source,  the blue light comes on (sometimes blinking, sometimes solid) but no music will play through it when I hook up the X5ii.
 
Looks like its a dud.

Hi, perseffect
Sorry to hear about that. Maybe you can try to change the sound source and the cables to see whether the issue happens in E12A only because of the battery. Or you may need to send it back to us for repair.

I've never had to use the reset myself, but is a "hold for 10 sec." type thing??

Hi, Mr Trev

 The reset may not take 10 seconds. You can just poke the Reset hole with an unfolded paper clip or other slender tools if you need.
