No no no... the op-amps comes with E12DIY are good reputable op-amps, and they sound reasonably good.  AD797 is very popular, also OPA604 has a lot of fans around the world.

I will compare them in E12DIY later.  I tested the Muses first, because they just arrived yesterday, so curious if the op-amps are in good condition or not, considering the amount of money paid.  

System matching is also very important.  So we test those op-amps to find out in what setup they sound best.

You won't be able to close the case up with DIP8 in E12. The opamp are on the opposite side and they are SO8. If you want to mod your E12, the opamp should be 2 x SO8 mono channel. MUSES just not going to work.

I am about to order some opamp from element14 myself, and it seems we are aiming on pretty much the same selection. Beside those in your list, I am also getting the AD4627-1, OPA627 and AD8599. Decided to pass on the NJM4562 as it is not available locally and it is measured to be almost identical to LM4562. I reckon I won't miss much on it.

 

Any other opamp you guys think are worth looking into?

Thanks for your review of the two Muses versions, Earphonia.

 

Based on your comments, I think the Muses 2 might be the one for me!

 

On a related note, I have a stock E12 on hand.

High risk... better not.  Without proper tools, you might end up with a dead amp.  And as ClieOS mention, no space for DIP8.

I was looking at the OPA627 but didn't know if I should get the BP or AP... or even what the difference was.  Which one did you get?

 

The opamps were cheap enough to try...only a buck or 2 at most so why not.

You may want to try OPA1642

Might not as refined as the Muses, but nice sparkling treble for mid centric IEM / headphones.

I am getting the AU ( U= SOIC). You should NOT be getting the AP / BP since P = DIP8, plus OPA627 comes only in mono channel. Two DIP8 on adapter will be way too high to fit inside E12DIY.

 

On a side note, you should not notice the difference in A and B version unless you have superman's hearing.

I didn't even notice it was single channel lol.

ClieOS, I'm very interested your test later on especially the AD4627-1, OPA627 and AD8599.  I should have a OPA627AU but still no luck to find it in my inventory.  I tried this Opamp in other DIY AMP which having pretty good Sound Quality.

 

I have tried the following during my holiday.  I'm using the BUF634 for now.  LM49600 seems less fit for E12 although LM49600 perform very well with my P4.  The following are dual channels opamp except the AD797. 

 

Muses01

Muses02

Muses8920

AD8620

LME49720HA (just for test, cannot close the cover)

LME49860NA

AD827SQ (also cannot close the cover although it is a DIP8 opamp)

OPA2134

OPA2277

NE5532

AD797

 

Due to too many to try, so I can only test them for a short period of time.  At last, I just picked 3 of them which should best fit (may not be the best Opamp) for my setup at the moment and I will test them further.  

 

Muses02

AD8620

OPA2134

I like the opamps manufactured by Linear Technology.

LT1037+LMH6321 is my most favorable combination for my E12DIY.

 

I've orderd LT1468-2 and LT1010.
I'll try to use LT1010 for buffer and new opamp combination.:biggrin:

I am thinking about LT1358 and LT1469. Trying to stick to their dual channels opamp as I already have plan for all three of my dual SOIC adapter.

The sound of LT1037 is more detailed , transparent and slightly edgy than AD8620.

LMH6321 has wider sound stage than BUF634.

 

I don't recommend this combination to OPA627 lovers.:wink:

Less detailed and transparent compare to LT1037 , but not edgy.
