Bass distortion might be a sign of clipping on the source, not the headphone (unless you know you have a very powerful source that has a lot of voltage swing). If you EQ on your source, say Clip+ and get distortion, I'll say you are clipping the Clip+ internal amp because it is unable to output as much bass as you are asking for. The point of bass boost on amp generally avoids the clipping problem as they are almost always has more power than the source, which means they can pump out more bass without distortion.

 

2. Would the ZO2 it somehow make that distortion point even higher meaning I can squeeze out even more bass with the ZO2 w/o distortion? Or is the max bass limited on the driver/headphones?

 

See answer in Q1. If you have enough power, you can certainly push the driver over its limit. But that generally means you are very loud and I will be more concern about your hearing than destroying the headphone.

 

3. Would I blow my driver with that much bass?

 

See answer above.

 

4. Is the sound quality noticeably better with the ZO2 over the E5 amp?

 

Yes. But ZO2 is not suitable to hiss prone IEM (high sensitivity, low impedance).

 

5. Is the sound quality noticeably better with the E11 over the ZO2? Because if bass is limited to what the headphone driver can handle, then I should be going for sound quality over bass quantity.

 

I'll say yes -  but I can see they coexist because they do best at different thing. E11 is for overall sound quality and ZO2 is for bass boost. At least for me, ZO2 works better with some IEM than E11 because I like more bass with them.

 

6. The E11 having 3 levels of bass boost? What setting on the E11 would the E5 with bass boost on be equal to?

 

Two levels. Lv 0 = no bass boost. Lv 1 is already 1dB higher than E5 bass boost (2dB). Lv 2 is 4.5dB higher than E5's bass boost. See the RMAA graph on teh 1st page and compared it to the E5 RMAA graph here.

 

7. How is the battery life on the ZO2 vs. the E11?

 

Haven't tested it yet, but I think report so far indicate that ZO2 might last a few hours longer than E11. But in general, I'll say they are both around 15hrs or so depending on how you use them.

Thanks for the great review! I am considering this with my new Shure SE425s. The E6 is such an improvement over the amp in the iPod (I use the line out from the dock connector) that it seems like a no-brainer.

Thanks a lot for your reply. My 580 ended up bein defective and my new ones are much better. 

 

I just received my ZO2 today and its horrible and sounds worse than my E5. I think it might also be defective. I'm using my Rockbox Clip+ and Pro 900. 

See: http://www.head-fi.org/t/589201/digizoid-zo2-3-impression-discussion-thread/150

 

So I went and bought the E11 and hope it will sound much better bass-wise. I will charge it and report back.

What does it mean when the input impedance is rated >5K? I'm trying to get some caps for a DIYmod, and wanted to know if there was a range or something for the input impedance for the E11. Are we talking about a 5K-10K range or 5K-100K range?

It means the minimum input impedance is 5k ohm, and that's all you need to know to calculate corner freq. (which is defined by the minimum input impedance).

I knew before I bought these that they seem a bit fragile. I watched a video and this guy had a dent on his E11 amp. That is why I wanted to get the ZO2, but I wasn't satisfied with the ZO2.

Now a week later, I get back from the gym and notice a dent on my E11! I think it was from my iPhone! Nooooooooooooo!!!!!!!!!!!! mad.gif

 

I can't find a good alternative with good bass boost around the same price.

 

wow..

E17 versus the E11

We’re talking strictly amplifiers here, and I have to conclude that the E11 is the better amplifier. More ample power, smoother, more refined. The E11 has much more depth in the soundstage though the width is slightly narrower. But everytime you have to choose between depth and width, it’s always the depth because that’s what gives you three dimensionality. Well anyway remember that the E11 is an amplifier only unit, no DAC.

what kind of case is that on your ipod?

post #834 of 1214

Hi Guys,
I recently bought a Fiio E11 amp and L9 cable to use with my iPhone 4s. When I listen to music I get a lot of interference (EMI?) from the phone. I can stop it by putting the phone in 'Airplane mode' but this means I can't recieve calls or text messages. Is there anything I can do to stop the interference? Is this a problem with all Fiio amps?
Many thanks.

EMI resistance vary from amp to amp. It can go from loud noise (enough to cause ringing in the ear) to barely audible. E11 is what I consider to be 'moderate'. E17, for example, is very quiet. There really is nothing much you can do.

Incase slider. And I didn't even run or anything, just lifted weights. I wasn't planning on using my iPhone but my Clip+ died during the workout.

I thought I'd chime in that the build quality on my e11 turned out to be pretty suspect.  I had the input jack go squirrely on me after about a month.  Now if I knew anything about electronics repair I could probably bend it back in to shape on the internal side, but being ignorant and lazy I got a headstage arrow instead.  Now I have twice the ports to ruin before it becomes useless!

post #838 of 1214

Does it make any sense letting the E11 play through the headphone jack of my sony s639?

post #839 of 1214

my e11 just died on me. it powers up and i get that turn on thump through my headphones. but i hear nothing after that turn on thump.

 

emailed fiio and the amazon seller about returns/repair. no reply until now.

Do you get the blue light and or red for charging?
