It would be very helpful for beginners like me.

Many thanks! 

 

Changing capacitor and resistor both require soldering skill, so don't mess with them before you know how to solder, especially on SMD.

I decided to sell mine on a well-known classified website, without opening it so I wouldn't take a hit on the re-sale.  I'm sure the E12DIY is a great amp but I purchased the HiFi-M8 while I was waiting for the E12DIY.  The M8 does everything I want in a portable and I don't see a real need for the DIY anymore.

 

Cheers to everyone who got theirs and good luck to those who are still waiting.

I think I may have found the best opamp+buf combination for E12DIY: OPA604 + LMH6321. It's very musical, engaging, and detailed without ever sounding harsh. Vocals gets pushed a little forward and everything just sounds so balanced and clear. Quite possibly my most favorite combination. YMMV depending on the headphones you're using with it.

 

IMO the E12DIY with the right opamp+buf combination is a significant improvement over the regular E12. It's very worth the price and I am liking it more and more each day!

 

 

Curious about the MUSES02 opamp, anyone knows where to purchase it online?

No idea how to use that removal tool...

I just used my fingernail to remove the chips.

Now trying diff op-amps with BUF 634.

Thanks for sharing! Sounds right up my alley. I'll give it a try!

I put the OPA604 in an Adcom GFP-565 stereo preamp some years ago and thought it sounded too dark and closed in. But this is a different application. I was curious about how this chip would perform when I found it was included with the set. Glad to hear it's working out!

I decided to give the amp a good burn in time before switching between the different oamps and buffs. This is because for me the standard E12 sounded horrible at times before it really settled to a very good sound signature.

Just tried to switch the buffer. Unexpectedly, it was more difficult than changing Op-amps since the buffer was located at the edge of the board. I now see why the removal tool is necessary.

 

My impression was that the pair of AD797+BUF634 has a better sound stage and warmer than both AD797+LME49600 and BUF634+AD604. 

This sound signature suits more with my Q701, and I'm now enjoying AD797+BUF634.

 

Pairs tried:

BUF634+AD8620 (original set-up)

BUF634+AD797

BUF634+AD604

LME49600+AD797 

 

What are you guys' impressions about different pairs?

Hi everyone.

Could someone kindly post some pictures of these blank PCB included for use (by soldering) op-amps different than those already supplied?

I haven't found anyone in my package!

post #400 of 1872
I have that same question also

They are inside the metal box, under the foam.

post #402 of 1872

Thank you very much!

it seems that they are fun to hide them! :o

It would be enough to report the location in the instruction manual attached.

Easteregs anyone? ???

WOW, I really gave up on them. Also I did not expect to see so many of these boards. Thanks FIIO and duyu. Without you, I would not even think to look under the foam.
