Hello,
 
I am a new member of head-fi.
 
I am planning to swap op amps of Essence One (basic model released in early 2012). 
 
I can’t afford muses so I am looking for other options.
 
In my country, the following op amps are easily available. And they are affordable too which means that I could try any one of these. 
 
OPA2227PAG4
OPA2227PG4
OPA2132PA
LM4562NA
LME49710NA
LME49720NA 
 
(LME9720HAs and the adapter required for them are not available). 
 
Could you suggest which one of the above op amps are more suitable/appropriate in which section? 
 
I/V: 
LFP:
XLR/RCA: (Note – I am not going to use XLR output). 
Headphone section:
 
Or shall I swap all the 11 op amps (or 9 since I am not going to use XLR) with one particular op amp (for instance LM4562)? 
 
I mostly listen to jazz vocals, western classical and world music. My headphones are K701 and HD598. I also got Swan active monitors so I would be using E1 as preamp to drive Swan speakers. 
 
Thanks in advance

At the moment I have tried the 6x LM4562NA, the vocal sounds more forward, but soundstage sounds less then the stock, so i'm back to the stock wink.gif

What conclusions should one draw from this experience? Stick to stock op amps if you can't afford muse 01? Right or wrong?

 

If one has to use LM4562NA, which section should be preferred? I/V or LPF or both?

 

Any suggestions for upgrading op amp in the headphone section? Or stick to stock op amp as not much improvement is expected?

IMO, I would stick with the stock op-amps unless you decide to upgrade to Muses01. I will give you an impression of Muses01 when I get mine from a fellow headfier soon and also whether or not an upgrade to Muses01 is really worth all the hypes.

By saying that, any other op-amps are very cheap, so doesn't hurt to buy some to try.

Good point. 

 

I look forward to your experiments with muses01. 

 

While searching further on this matter on google, I just came across an interesting blog by NwAvGuy where he has demolished many myths associated with "hi-end" op amps and op amp rolling. To me, a lot of these discussions are useful and eye opener as I am entering into head-fi territory.

Yeah, I have also read that blog and I can CONFIRM that different op-amps DO make the sound DIFFERENT!

I am curious to find out for myself as well. Im thinking about getting some NE5532's to swap in and give a listen.

Hi,

I would suggest you to try OPA2132PA at I/V, sounds best (for me) with OPA2107P at LPF, good with LM4562NA at LPF.

For XLR/RCA choose between LM4562NA, LME49720NA with slightly less bass. LME49720HA (not on the list) sounds brighter.

I'm looking at Mouser.com for the NE5532 opamp and there are several different varieties. The two that appear to be correct for the E1 are the NE5532P which is "PDIP-8" and the NE5532PE4 which is "DIP-8."

 

DIP-8 is what I want, right? So I should order the PE4?

DIP-8 and PDIP-8 is the same housing. P means plastic. Most cases are made of plastic, many of ceramic. PE4 is OK for you.

Why are you getting the NE5532? Isn't that the stock ones?
post #2369 of 3076
Thanks for the info!

Just curious to hear what if any difference the Muses opamps make.

Having received my muses01 from Gandah yesterday, this is my first impressions of them:

The vocal with the stock sounds more distant from your ear (to me I first liked it because I thought that make the soundstage sounds bit wider). The vocal on the other hand with the muses01 sounds closer, cleaner and also with much more details. The soundstage is very good too even though I think the stock has a tad more.

Overall I am very happy with it. Is it worth the money? Well if you're going to pay 200+ for them I say NO. But if you can find them under 200 (thanks Gandah ;D) then I say YES. Bevery ccareful with FAKE ones out there though with some of the cheap ones (look at my earlier post here to tell the difference)

Hope this helps a bit wink.gif
