19 $, according to the first post in the thread.

 
I do not know how the others did it, but I clicked the option, that I have bought something over the internet e.g. Fiio must have paid the Paypal-fees. Somehow I think, I did it wrong.

I am not sure I understood the problem, so all I can is, try to contact James, I am sure he can help you (well he will probably see your post and try to help from here too).

Im sorry I missed that.
Gonna deposit now.

It is either you choose to send the money as a gift or send it like it was a purchase for something. I did not send it as a gift. They way I sent the money, Fiio will have to pay the Paypal fees for the 19$.
 
I do not know, if this is ok.

is it too much to expect E12 to be able to drive Beyer DT880 600ohm with any of these opamp?

The opamp is lesser a problem, the gain is the main issue on high impedance headphone as you might not get enough volume if the gain is not set high enough. If we assume the gain setting is the same as the normal E12, then you should be alright.

the E12DIY will comes with a detail circuit diagram which help people mod it and get the best performance . for example, high gain good for very high impedance headphone with some very low output level source like iPod.
 
but the hiss will also higher than low gain. it just depend on what you will use it .

yes, we will pay the paypal fee in our side. it is not a big deal ( 4%).

 

[MrScratch]

I did the same mistake, then.

I'll make sure to chose the other option when I'll pay the balance. (⌒_⌒

interesting. but i thought the choice of opamp will affect the output power.
Also, what is the affect of changing the buffer? is there anyone knowledgeable enough to give an expectation of each opamp/buffer in this package?

 

[hellfire8888]

another quick question ..is it possible to purchase other opamp on our own like cs4398 and just plug it into the slot?

CS4398 is not an op amp. It is a DAC by Cirrus Logic.

If it is opamp directly to output, your assumption will be correct. In the case of E12DIY however, there is a buffer stage so the buffer will be handling the current output while the opamp is there for the gain. Since gain is set by the feedback resistors, different opamp will not show any major difference in gain.
 
Every circuit is designed differently (and hopefully so). There is really no way to predict how different combo will sound.

What Panda said ^. But regarding opamp rolling - yes, it is possible. However, opamps ain't universally compatible to each other and therefore you need to be absolutely sure the opamp you swap in will at least work on the supply voltage, or else you might risk damaging the opamp or the amp itself.

I got the E17 should I get the E12 special edition ?
any suggestion

do you have any high impedance headphones? or headphones that are hard to drive (e.g. planar magnetic)? if yes, then you can try.
also, E12DIY — is a good way to try different opamps.
