But:
 
Here're some notes from @ClieOS from earlier in the thread:
OPA627 + BUF634 for warmth and smoothness
 
Is it a stock op-amp, right? So, as I read in this thread stock op-amp is best, and I can not use MUSES. Right? 

 
OPA627 isn't stock, you'll need to get it and solder it onto one of those spare adaptors. As for whether you can uses the MUSES, Try popping in a DIP8 opamp first to see if the case can slide shut without filling/grinding. It so happened that mine was one of the lucky ones so I was able to use OPA2227, TLE2082 and JRC4556. A bit of a squeeze but that was it.

ok. Now I have a good deal. 90$ for E12 and 150$ for DIY version with 627, 827 and HA-5002 included. And can not make a choice. One man told that E12 enough, another that DIY better. But almost twice price.

Depends on what you need to drive with it and whether you need the bass boost.

Oh..DIY has not a bass boost (( It is a very bad news. Now I find bass boost a good mode in E12. It adds more dynamic, volume, energy.

The DIY does has a tremendous high gain, enough to drive the likes of HD600 and ATH-R70X decently, as well as a superbly black background for sensitive iems. It's more for versatility, so if you can live without it then save money.

sstyle: Buy both and send the E12 DIY to me

I'd love to have a second DIY to A/B compare different buffer/opamp combinations

Done.

No, the E12 DIY should be on my desk :wink_face:

Here're some notes from @ClieOS from earlier in the thread:

NJM5532 + HA-5002 for its neutrality and transparency.
OPA827 + HA-5002 for its balance between smoothness and detail.
OPA627 + BUF634 for warmth and smoothness
MUSES01 + BUF634 for analog like musicality
MUSES02 + BUF634 for overall versatility

Did anyone get the chance to compare the E12DIY in non-stock configuration (e.g. using any of the opamps above) against the Centrance Hifi-M8?

 
I've been suggested in the past that the M8 represented an end-game DAC/AMP in the world of portable music, besting even the likes of iBasso DX100 or AK 240. And while the E12DIY is clearly very good and by default not far behind the M8, from comments in this thread it seems that in its stock setup it reaches only about 60-70% of the amp's full potential. So I'm naturally wondering if the E12DIY can be configured to reach the sonic performance of the M8...

Who compared OPA827 vs OPA627 with BUF634? I prefer more warm sound.

I have both and prefer the OPA627 overall which is good news for you because it's also the warmer of the two

 

[RedTwilight]

   
Done.

 
Try using a (slightly) better interconnect. From normal cable to an OFC one, there's a huge increase in clarity. After that not so much though. Beyond something like the iBasso CB06 (which is still a little overpriced imo) I can't really tell already.

Thanks! May be L16/17?

Would be best if you can give them a try. 

 Kinda hard to predict the sound. I didn't particularly like it but that's just me or perhaps a result my song choices.
 
Or you could just stick to the stock one for a couple of months because seriously they do what they need to.
 
Then when you want to change you'll get that upgrade in sound haha..

Nice. Thanks!
 
So I interested in test:
 
HA-5002 + OPA827
HA-5002 + OPA627
BUF634 + OPA827
BUF634 + OPA627
LME49600 + OPA827
LME49600 + OPA627
 
Ok, if 627 more warmer, I should test
 
HA-5002 + OPA627
BUF634 + OPA627
LME49600 + OPA627
 
But I read that LME49600 is very close to BUF634. And as result I need to compare HA-5002 vs BUF634.
