I just replaced all 6 NE5532 with the Muses 01 op amps. My first impression has been improved detail across the board. The most noticeable difference, at least initially, is increase "oomph" and detail in the bass. Vocals also seem to be more transparent and musical. I will try to post more impressions after spending some more time with them.

Did you get them from DIGIKEY?

 

And you're right, there's a lot more detail along with a more impactful bass. Bass is more full and has more punch rather than slouchy from the NE5532. 

 

The largest difference i also found was the Vocal forwardness. It's very very transparent and musical. If notice very closely, you'll notice better sound separation and a less aggressive noise floor.

Treble is improved as well, but not too much.

Digikey would only sell them in lots of 50 so I ended up finding some on ebay. They were from a chinese dealer but he had a high rating so I took the risk, and I am very glad I did. I pretty much agree with your impressions. I have been looking for a difference in the treble and your right I do think it is improved, but not to the extent the bass is. Really added the kick that I felt the WA2 was lacking. Either way I am definitely enjoying the music much more than I was before!

 

This is a link to the dealer on ebay. Shipping takes a while since it's from China but you get what you pay for.

Shipping was actually really fast from them. That is the same place i got my MUSE01's from.

I think it took me 3-4 days to get it since he sent it as a small letter.

 

He sells authentic muses. I traded multiple emails with the guy because i was also unsure, in which he says that the op-amps were directly from JRC/NJR Co.

He even showed me proof of his transaction receipt.

 

You'll notice the treble and sound stage a little bit more when listening out of the RCA ouput.

 

I'm glad you got rid of the NE5532's. It's really hard to go back to them after listening to a few hours of the MUSES01.

Hi Guys,

 

I have been enjoying my Essence One for a while, alternating between using my Sony MDR-F1s, just so comfy can forget I'm wearing them, and my Denon D700s.  I was just wondering if anyone had any recommendations for speakers to pair with it?

 

Thinking about getting a pair, for use when I'm not the only one wanting to listen/watch, and for when I'm not sat at my desk.

 

Any advice would be much appreciated.

 

Cheers

I've used the Essence One on:

 

Audioengine A5+, A5, and A2 (A5+ has better features, and i'd gladly pay $100 more for it)

Rokit RP10-3 and 6 (RP10-3 sounds better)

Emotiva Airmotiv6 (GREAT BASS)

 

They all sound good, however i like the Airmotiv a little more for their bass.

I would go with a desktop amp and a set of passives bookshelf speakers, you can add a subwoofer later on.  That will give you the best sound for your budget and give you the best overall upgrade paths and flexibility.

Thank you for sharing that sellers contact link with us!

And thanks alot to everyone else sharing your thoughts and expertise here. I've been following this thread almost since the beginning and you've all been a BIG help to me already redface.gif

 

I may try the MUSES01 out in the near future, but first I will check how well the AD797-BR and/or the LME49990 will perform inside the E1 (somewhat an experiment). I will blindly roll all the headphone related opamps on the board and see how it synergies with the HD 800 I got here and been using for quite some time now.

 

So far I'm really statisfied with the perfomance of the stock good'old NE5532's it comes with.

Although they are not not the clearest I've heared nor got the widest soundstage they really make a got pair with the HD 800.

They tend to damp the overall sound signature a little bit and make these headphones sound less harsh & cold and also emphasise the bass exactly to my liking (and I'm listen mostly to slow and deep electro with them! redface.gif ).

Make's me wonder if the E1 was orignally build with the HD 800 in mind as one or two guys from Asus I know of are actually using the E1 together with the HD 800 at home smile.gif ... but I rather think that's just me hallucinating right there biggrin.gif

 

Anyway, thank you all for your input! Hopefully I will share mine from now on too redface.gif

Now that I have taken the plunge into swapping op amps I want to try swapping the LM4562 with the LME49710HA. Where is everyone buying them already attached to the adapter. I can plug op amps in but I don't think Im comfortable soldering and such. I found some on ebay from thailand but it may not be till the end of march before I would receive it. Any sellers closer to the USA?

I posted the links in the previous pages.

 

You can only use it for the RCA Out. To use it for the headphones, you'll need to buy a few DIP-8 sockets to raise it up a little or else it would conflict with capacitors, volume meter, and headphone socket.

 

And yes, it's the one on ebay from Thailand. It took me nearly a month to get the pcb. I get things faster from China.

 

I have some extra DIP-8 Sockets left if you need.

I went ahead and ordered from the thailand guy. I ordered one set for the RCA out first. If I get some later for the headphones I may take you up on that. GREAT....I thought the two weeks waiting for the Muses was bad enough. Amazon prime has spoiled me rotten...

The muses got to me in 3-4 days. bigsmile_face.gif You must have had bad luck.

 

 


 

Working on Wima Film Capacitors. Look at the size of that FKP.

No room for the Large Green 8200pF, so it's going to be mounted underneath the PCB.

 

Before the work:

 

 

Removal Begins:

 

 

 

First Capacitor In:

 

 

Many To Go: (Wouldn't want to damage $50 muses on accident)

 

 

Ran Into a problem: (Asked 10 Yr old to help me hold, this was what happened...he yanked on it..)

 

 

I know what you're thinking.. "How did his iphone take such a good close up picture?", Truth be told, i have no idea.

 

The pcb wire that ripped off the eyelet seems to run to the top of the middle resistor.

Would it be okay to use a 30AWG wire to connect the resistor to the capacitor lead?

Wow Tim, you look like you're turning the E1 into an entirely different beast. (Ouch for the ripped out wire!)

 

My LME49710s have arrived and were very nicely packaged (bought from the Thai seller), although he charges 5usd for each item's shipping instead of combined shipping (stating that it's for insurance)... The build on the op amps seems to be good though. Still waiting for my DIP8 adapters to come, so can't use them yet...

 

Seems like the general strength of the E1 is it's transparency, which improves as you roll better and better op-amps. Can't wait to change out my whole I/V section, but it'll take time to muster the money for 4 more sets of op amps. I've already spent more money on op amps then the difference between the base E1 and the MUSE edition... Sigh... New speakers will just have to wait...
