  slightly on spacious side..... if 1 is intimate and 10 is spacious....muses01 and LME49600 combo is on 6-7 side

Nice - sounds like what I would enjoy. Now the only challenge is trying to modify my case sufficiently without weakening the metal.

Just jumped on the diy wagon... Which combo gives the most spacious sound?

I really like the OPA1611 + LME49600 combo from the provided kit for a spacious, detailed sound.

 

[Fiiorless]

The LME49990 LME49600 combination sounds the most spacious to me but is less enjoyable to listen to than the MUSES02 LME49600 combination which seems to have more treble detail especially listening on the SHURE 1840's.
 
The OPA1611 LME9600  is far and away my favourite of the supplied combinations.
 
As an aside I measured the output impedance with various buffer opamp combinations and it varies between .13 and .20 ohms from 100hz to 20 KHz. The lowest impedance was with the factory shipped combination but as we are talking about .01 ohm differences its not really significant. What surprises me the most is how much better the bass sounds with the MUSES02, it is not at all subtle.

Here is a list of OPAMPS that I want to get:
 
LME49860
NE5532
LM4562
LME49720
NJM2114
NJM4580
NJM4558
NJM4556
OPA2111
OPA2134
OPA2227
OPA2604
OPA2107
 
Is it safe to buy one of those OPAMPS on ebay or do I have a big chance of getting a counterfeit product?

The question is, is there any reason why you can't buy them from a well-known electronics parts supplier?

Cause on a 70$ purchase I'll have to pay a 75$ S&H fee to have it sent to Israel if I choose to buy from Mouser.

Have a look at shipito.com
I use them all the time, they can repost from 3 different states to avoid US state taxes and all up costs to Israel should be less than $20.

RS Components and element14 both operate in Israel, as far as I know. You should be able to find at least half of those opamp from either companies.

Mouser has a branch in Israel too but they don't carry any stock so every order is shipped from the States.

The OPA627 is also a great choice. It's impressing me mightily.
 
While on the slightly pricey side, it's easily available and is a good deal from Brown Dog (2 channels pre-soldered onto a Brown Dog adapter for $52, which is just a tad higher than just buying the chips themselves from Digikey or Mouser).

MUSES02 will probably supplant the OPA627 for me (after sufficient burn in), but OPA627 is a quality chip, no doubt.

Let's ask a different question: If I got the muses01 and the ha-5002,is there a reason to look any further?

Please note that dual OPA627 on a single-to-dual Brwondog adapter will not fit inside E12DIY.

So any it renders any single opamp unusable with the E12DIY.

Of course not. You just need to mount them on the blank adapters that come with your E12DIY (*they are underneath the foam, inside the metal box).
