Another would be AD797, but it's not usable on the Essence One.

 

You could give LME49990's a try, that is what im going to do now, for the buffer stages.

Thanks again.

 

Regarding stock. Yes, I think so too, but can't get enough. Not satisfied before every detail is gone and the bass is muddy, lol. Before the unit was burned in I found it to be a bit harsh, but not anymore.

 

K, thanks, will try to get a pair of LME49990's. I have some opamps which I haven't tried yet.

  • LM4562NA Dual High Performance Audio Op Amp (4pcs)
  • OPA2107AP Precision Dual Difet Operational Amplifier (2pcs)
  • BURR BROWN OPA2132PA (2pcs)

 

Any recommendations using any of those?

You are getting the same results as most of us them.

Detail is completely bashed by the muddy bass, and treble smooths out before it can even get half way.

Most op-mps that i've found makes the sound more neutral, so not sure how the darker would fit for you.

 

Essence One already has LM4562 in buffer (XLR & RCA).

If you're listening with headphones or through RCA, what you can do is remove the 6 NE5532.

take the LM4562's (2) from the XLR buffer.

Replace those 6 NE5532 with 6 of your LM4562.

 

Listen and see if you like the difference.

There should be more detail, treble, and less muddy bass.

Sound stage and separation should increase as well.

Looks like you got a somewhat similar set-up to Kenion.

Thing is with the treble, i use Audioengine A5+ and Audez'e LCD-2 which isn't spectacular in the treble area, so the 49710's help with this.

How much smoother is the OPA827? (how lower is the treble?)

I could use a little bigger sound stage, but not by too much.

Mainly want to focus on an op-amp with more detail/treble/separation.

Have you tried the OPA827 in buffer?

How does LME49990 compare to 49720/4562 in buffer? 

I'm not too much of a sound stage guyy, one of few reasons why i sold the HE-500/HD-800/AKG K701.

If you're sure that they have more detail and separation, it's my queue to get them! Those are the two most important thing to me.

How is the treble/bass/neutrality compared to the AD797 or 49720?

Read back to earlier pages bro, this was discusses for at least 10 pages.

It doesn't come with gain switch, unless you RMA it for a new one and specifically request for the switch to be installed.

Even with that, the gain switch muses doesn't sound as good as the the one without.

 

Tim

It is noticably darker and more mid focused whitch was a good thing for me because with the 49990 in i/v the sound was too bright with the 49710. I will make some more 49990 and test them also in the buffer.

Thanks again man.

 

I sold mine so i have to re-order.

 

Headphone buffer with the 49710HA still sounds dark when using with LCD-2, so it's a good match.

I'll be sure to get enough for the XLR Buffer and see how they compare to the RCA running 49710HA.

I am sure you will be having fun with the LME's.

They are very detailed and slice your music into many diffrent layers of sounds.

They are just lacking the "flavor" the AD797BR's have. They are plain neutral and smooth (in my point of view).

 

I didn't like the LM4562's in combination with the HD-800. I remember them being too bright.

Thanks, i'll give them another shot. (For XLR and RCA Buffer only)

49710HA Headphone Buffer is needed for Audeze LCD-2, but i'll switch to the 49990 once or twice to see how different it is, and see if i like it more.

 

Neutral/Smooth is good enough for me, as my speakers color music already.

 

I don't like the LM4562 period.

LME49720 is just "OK" on my list.

 

How are you liking the OPA2227?

I've bought a batch of both OPA2227's and OPA2111 KP's from this guy http://www.ebay.com/itm/181068808255?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649.

I ended up prefering the OPA2777 over the other. I have them running on the I/V (where my LME49990's used to be originally).

They are really good... I swapped them around a lot and compared them with other combination of opamps but I always ended up with them.

They emphasize the lows nicely and add a nice "oomph" to the bass as well, without being too muddy sounding (like the NE's).

For me, they are my personal successor over the NE5532's in every way...

 

I usually didn't like the LME49990's in the buffer as they are a bit too hissy and just a tad too bright in there but the OPA2227's seem to tame them quite nicely. So I guess they are staying... unless... I happen to get my fingers on another batch of new, exciting opamps... hehe :D

 

I have them all placed on top of DIP8 adaptors from the seller you got yours from too, for a hassle free swapping tongue_smile.gif

Done deal!

 

I'll grab some LME49990 and OPA2777 for Headphone & RCA Buffer.

Will compare them versus the LME49710HA & LME49720.

 

When i did my modding last time, in the end the right side speaker wasn't getting signal.

I thought one of my Elna Silmic II capacitors was DOA, but seems like something was just soldered bad.

 

It was impossible to get the capacitors leads into the hole a second time... so this is what i had to do.....

 

 

 

 

Had to drill a hole to fit the wire & capacitor leads.

(2) 100 ohm resistors on the right side fell off, so i have to replace those...pain in the &$$.

 

Left side is working now, hope the right will too.

Norway, if it wasn't for your YouTube audiophile reviews I probably would not of gotten into this great hobby, I purchased the asus E1 based on your review beerchug.gif

 

Knowing your reviews and the gear you use, go for the muses man, your LCD3s will love them. My TH900s sound very similar to the LCD3s which has been described by many owners of both HPs, however the LCDs are slightly on the darker side of things, which I think with muses will workout being a good pairing.

Any customers that are based in North America that have received a MUSES edition without the jumper will have their unit swapped (if that's what they want). I only deal with the NA region, so other customers will need to contact their local ASUS office (only where stocked).

How many time to fix the upsampling problem that cut the highs frequency .
I really like to listenig the incredible result of upsampling in particular the exceptional layer in low frequency but the crap cutting over the 12khz It really does anger .

Right now my combination is : OPA2132 (4pcs) in I/V, OPA2107AP in LPF. It gives the best bass (not dominating, but precise, deep, differentiated, full and kicking) of all combinations tried so far (not tried MUSES01). Mids and highs are clean and detailed, soundstage is not as AD797br, but on average side. I think that this would be a great combination for basic factory shipment.

Sounds pretty complicated, i think just removing the solder would have been easier or were the leads too thick for the hole? 

 

I tested the lme49990 in the buffer, it also a nice op, brighter than the opa827 so if you are looking for a bright sound you should check it. With the 49990 in i/v and opa827 in lpf the sound was brighter than neutral, actually most op-s are too bright in the one. The 49990 and 827 in lpf and buffer is one of the few combinations that is not too bright.

Has anyone tried swapping out those blue diodes with red or amber ones? Red would look bloody awesome.

Thank you, that's very kind!  :) I don't describe myself as an audiophile though, I even say so on the channel page, but I might be in denial, lol. E1 offers the most bang for the buck that I've ever experienced with anything else. Very exciting to see that people here are yielding such great results by swapping opamps too -- seems very promising!

 

TH900, drooling ... :) I love Denon AH-D7000 so the TH900 has to be owned sometime! Do you find it to be a good match with E1? Did you get the MUSES edition? Will probably get MUSES, but not until I've rolled some opamps. I have two standard editions to simplify the rolling and maybe use one of them as a bedside rig :) Right now LCD-3 and AURALiC TAURUS and ARK MX+ is king, if E1 MUSES can top that I will be gobsmacked.

 

Which opamps do you like with TH900? Maybe the same combo will be good for D7000.

Cool, thanks for sharing. A bit short on those OPA2132 to do the same, having just two. :(

 

Do you guys get most of your opamps from ebay? Kind of scary to shop there, with the risk of buying fakes, but getting from reputable sellers with 100 % positive feedback and at least 500-1000 feedbacks should make it safe, right?

Even if buying from high feedbacks, you could end up receiving fakes and still not know.

I usually buy from those descriptions that have verified their op amp autencity.

Whichever op-amps i swap out for i/v, i still preferthe muses01.
They go well with pretty much anything for buffer, so at times its hard to find a better performing op-amp for the buffer stage.

When you say diode you mean the blue light emiting diodes?
I have already changed all of mine to red 3mm flat heads (flat looks way better on the essence one).
Not only did i change those, i also went on changing the surface mount leds that light up the power button with red as well.

It's a little lless bright now, but the color is awesome!
The previous blue color was way too bright, dont you agree?

@WhiteRaven

Leads were too short and big, could not push them in the socket, and it would of looked ugly if they were mounted sideways.

I got one in so left side works now, took quite awhile to check for continuity so that nothing went wrong, its the right side that im worried about since another 100 ohm resistor came off, but it seems like a simple fix.

Now that i listen to the 49710 more, it does sound a tad bright, especially in speakers.
Maybe its cause im a treble freak.
I'll be auditioning the opa827 and lme49990 soon.
Im guessing since its more neutral, being less bright, if should have more bass/warmth than something like the 49720 right?
