Hi Guys,
 
Over the last few weeks I've been reading review after review of the Fiio E12 and it seems it's what I'm looking for to replace my E11 with my HD600/ipod while I'm roaming around the house. I have been thinking at times when I want to "rock out" that I would love just a tiny little boost in the sub bass regions as I find it sometimes lacking for my punk music depending on my mood. I thought it would be great to get the E12 as reviewers claimed it to have a 20Hz or 40Hz 5db boost. And, it has crossfeed which I have always wanted to try.
 
So tonight I pull the trigger at headphonebar and order it. After, I realize the specs say 5db @ 100Hz... What the heck? A quick check over at the fiio site shows the same. Did they alter the bass boost frequency region?? I find the bass boost on the E11 too high up in the frequency range for my tastes and it muddies up the sound. I've googled but can't seem to find a definite answer.
 
Thanks for any input you have!

This should explain why:
 
 

... The bass EQ is basically a sub-bass boost in my review unit (first batch). It starts just under 200Hz and peaks around 25Hz @ 4dB. Due to feedback from the first batch, FiiO has decided to move the boost a bit forward in the frequency so the next / current batch will have a broader boost and peak closer to 70Hz. As far as how much / wide a bass boost should be, it is all about personal preference. I like the sub-bass boost because it adds really solid rumble to the music without adding much coloration into the overall sound, but a broader bass boost can be beneficial if you also want to add warmth to the music.

Thanks for that quote. It is unfortunate news. I do not enjoy the bass boost on my E11 with my HD600, so I leave it off. I find the HD600 more than capable in the higher bass frequencies and that the E11 boost muddies the sound slightly. I got caught up with hype from the reviews I read of what I guess was only an initial batch. Sadly this purchase could have been easily avoided had I checked the specs on Fiio's websites rather than trusting reviews made back in may and june. Should a company not add revision numbers or something to their products if they decide to change them along the way?

I'll hold my judgement until I get the product in the mail though. Perhaps I will enjoy the boost and find it to be more refined. And if not, maybe someone will trade me their early production model?
