Fiio's official spec says +4.2db at 100Hz , which I assume is what the newer batch does. Based on Fiio's graph, bass boost before 100 Hz should be even higher than +4.2 db.

However, Fiio's graph might not be updated to reflect batch 2 bass boost (it is contradictory to spec's +4.2db@100Hz). It shows a +2db@100Hz, which seems to be that of batch 1 bass boost.

ClieOS measured a batch 1 bass boost here and showed a graph similar to Fiio's: http://www.inearmatters.net/2013/03/impression-fiio-e12-mont-blanc-way-to.html?m=1
ClieOS also indicated that batch 2 bass boost will be broader and less deep/tight.

Yeah, it's not that high. Subwoofers usually crossover (in?) at around 80-100 Hz depending on personal settings in a home theater, for reference. I haven't heard the new E12, and while I stick to liking what I'm hearing, I doubt that they're Really changed. Lets try it from this angle... Anyone with a current E12, have you noticed that turning on the bass boost over did it for a particular song compared to "off?"

I don't like the bass boost all that much...it seems to bleed into the midrange and raises the overall volume level.

I don't like bass boost bleeding into mid range either, which is why I prefer boost to subside before 100Hz (if I have to use boost). Your batch 2's boost bleeds a lot more than that of batch one.

It depends on what headphone is used. I liked it with the MA900 on bass light music, but not bass heavy music (which the MA900 sounds fine at default). I hated the bass boost with the X1, but that's because the bass is already quite prominent.
post #2241 of 3026
I love the bass boost with my X1's, but that's possibly due to having batch 16 ;-)

I use the bass boost with my shire se215 but with my primary IEM the GR07 be I keep it off. Anyone else here use this with there Fiio X3?

Heh, i got so used to E12 in my setup, that today when amps battery unexpectedly died I was just completely stunned by how bad it actually sounded without it :-D

If there is ever a successor to the E12 it would be nice if it employed a DC servo so it would get around having to use coupling caps (I am presuming that is what the two 2.2uF polyester caps are)

That's awfully small for output coupling caps!

They are Probably power supply bypass caps for noise suppression..

Good point, I should have caught that :confused_face:

 

Actually I think they may be inter-stage coupling caps. 2.2uF is about right for that.

 

Maybe James will comment.

I think you are referring to the bass boost.
 
Here's a link to the FR graphs that James provided earlier relating to the initial batch's bass boost versus how it was going to be (and how it was) changed:

The difference sounds much more significant than it looks

And this confirms what folks are saying. The knee frequency has gone up by almost an octave.
