Hey people,i have been reading up on much debate on the FiiO spoiling the armature drivers of IEMS.

is this true?Because I am planning on a UM1 or SF3 but i also want some bass to it so I was planning to use the FiiO E3 amp which i got but then this...

when you say spoiling , do you mean it literally destroys the armature or do you mean it makes the sound worse? I use my Fiio E5 with my PFE all the time and while it does make it a little muddier , it makes up for it in added mids,bass, and warmth.

Here's the relevant thread although, I'm very curious about this myself. You should be safe with the E5, but maybe that's not so for us with the E3? Could someone knowledgeable about electronics explain this? It's dangerous to use the E3 with a line out? As in, like a laptop line out?

When i say spoiling it,i mean like frying the drivers...not making it sound worse.

Is there any problems with armatures on other amps reported other than FiiO?

It is not the line-out that causes the problem, but DC offset. On rare occasion, even output (may it be headphone-out or line-out) with coupling caps can have DC leakage. If the DC leakage is bad enough, it will be amplified by the amp (that has no input caps, such as E3) to a voltage high enough that can cause damage to the headphone. The easiest way to test of DC leakage is to connect the left / right channel to a voltmeter and measured them against the ground channel, then start and stop playing music a few times. If there is no DC leakage, the voltage should be very low all the time (near, if not zero volt).

So far, I have tried different E5 with q-JAYS, s-JAYS, SA6, UM2, TF10, SE530 and SHE9850. All of them are still working fine.
