2 pieces of Muses 2 with sockets for $134 including shipping from Amazon. Yikes!

http://www.amazon.com/MUSES02-Quality-Bipolar-Operational-Amplifier/dp/B00B08AYIE

Is it cheaper at Mouser?

  Great! Thanks for the help.
 
Im about to buy a pair of OPA627SM and  a pair of LME49710HA as well, do you think the TO99 + adapter will fit inside the E12DIY?

That will be a big NO.
 
As mentioned by a couple of guys before, even DIP8 has clearance issue on the E12DIY. You'll want to stick to SO8 + stock adapter as much as possible.

Prices of Muses Op-Amps from Mouser Singapore (prices are in Singapore $, to convert to US$, divide by 1.3)
 

 
Muses01 is with J-FET input, Muses02 is with Bipolar input.  Usually Bipolar input is not easy, high DC offset.
Is Muses02 stable in E12DIY?  Any measurement of DC offset on the output?
 
Thanks!

E12DIY is designed to work with bipolar opamp though (i.e. OPA1611). I'll give it a measure when I received mine.

Right!  That's cool!
I have mine for a few days now, still listening the default setup AD8620 with BUF634 and trying to get familiar with the sound signature... a bit dark for my taste, which is strange, AD8620 in my previous experience was a bit bright and lively :)  I only tested with Fiio X3 so far, maybe what I hear was the dark signature of X3, will try more with other DACs.
 
Will try Op-Amp rolling once I have time and post my impression.
 
Now ordering Muses01 and Muses02 from Taobao :)
