AD8620 - good detail, almost edgy, a little flat on soundstage and lean on lower end texture
MUSES01 - near perfect balance. ultra smooth and full sounding with lots of texture
MUSES02 - Better depth than muses01, more layback with a little less texture
MUSES8820 - similar to MUSES01, but scaled down and not nearly as grand
MUSES8920 - similar to MUSES02, but similarly scaled down like 8820
LME49720HA - very clean and clear with good air and soundstage
OPA2107 - a little mid centric, nothing remarkable
LM4562 - similar to LME49720, even cleaner and leaner, very O2 like.
OPA2209 - a little veil on the mid and lacking detail
AD8066 - great micro-detail and decent soundstage, but otherwise unremarkable
AD797 x2 - neutral but edgy, like AD8620 with better depth
OPA1611 x2 - laidback, if not a little dark
OPA604 x2 - almost like opa1611, rather smooth.

 

So far none of the stock opamp really wow me. Beside MUSES01/02 which I have expected to be pretty good sounding, the only other opamps that really surprised me are the LME49720HA / LM4562 (*they are said to be the same internally), LM4562 in particular is very transparent and clean, giving a similar presentation as O2. It will serve as a great choice for those who are looking for wire-with-gain / colorless style of amplification. MUSES01 and 02 more or less about the same level. 01 has the advantage of having a great balance between detail and texture, while 02 has the advantage of having better layer and soundstage. I'll say 01 is a bit more musical while 02 is a bit more neutral in comparison to each others. Though by themselves, I won't say any one of them is really on the musical or neutral side. They are all fairly well balanced. The opomp I really won't recommend are OPA2209 (or OPA209) and OPA2107. The rest are just unremarkable one way or another.


Would AD825 (two on adapter) also work? Gonna pick up my E12 DIY at the post office tomorrow and thought I'd give it a shot if it's compatible.

Did you use the side-by-side adapter? Photos would be great whenever you have a chance.

More info about how they compare to the Muses would be great! Whenever the time is right, of course.

 

Will post some picture later.

 

As far as sound impression goes, I reckon OPA627 is right between MUSE01 (texture) and 02 (resolution and soundstage), but closer to 01. It is not quite as good as either, but I don't feel like it is any noticeable downgrade either.

It should work. I might get a pair myself later on.

I believe only Mouser has stock in the U.S. Digikey needs 500 minimum order (or is it 100? Well, doesn't make a difference). Both are $70+ a piece. I would guess using a forwarding service like Tenso and get it from the Japan distributor will still come in much cheaper, as ithey are sold in Japan for half the price.

The shape and the color of the markings are slightly different from those of legit ones.

The color should be gray, not white.

 

Here is the photo of a legitimate MUSES02 that I bought off of akizukidenshi.com,

an authorized reseller.  (see http://akizukidenshi.com/catalog/g/gI-03417/)

 

 

A legit muses02 has very soft leads, so if the leads of yours are as hard as other standard

JRC op amps like NJM4580, NJM2608, NJM5532, NJM2114 and so on,

I guess they are remarked NJM4580s because they have the same circuit as MUSES8820

and MUSES02.

Thank you for your feedback. i am now contacting the seller on taobao and see what he can do. as he insist what he selling is original.

i have contacted the seller and he is insisting his product is original. i will try to get my op amp from the japan store and then do the A and B comparison and also the SQ of it.... 

post #562 of 2221

I've been comparing:

Muses01

Muses02

OPA2209

AD8599

Using buffer LM49600

All are compared with another E12DIY with stock AD8620 and BUF634.  As I have 2 units of E12DIY at the moment, it is easier to reference to the default sound signature.

 

Source is Yulong DA8, this time with IEM JVC HA-FXD80 (previously I've been using Beyerdynamic T1 for testing E12DIY).

 

I'm surprised to find that AD8599 is a great contender to the Muses :bigsmile_face:

http://sg.mouser.com/Search/ProductDetail.aspx?R=AD8599ARZvirtualkey99990000virtualkey584-AD8599ARZ

 

On the above setup, with JVC HA-FXD80 as monitor, I find that AD8599 sounds best :ksc75smile:

On E12DIY, ClieOS is right, OPA2209 doesn't sound interesting, only roughly about the same as stock AD8620.  Later I will compare it with Dr. DAC2 DX, since OPA2209 was sounds pretty good in Dr. DAC2 DX when I tried some months ago.

 

With Beyerdynamic T1, Muses02 is still my preferred Op-Amp, but with JVC FXD80, Muses02 has too much midrange to my liking.

AD8599 is closer to Muses01 than to Muses02 in term of tonal balance.  Midrange is a tad laid back compared to the stock AD8620+BUF634, Muses01, and Muses02. But AD8599 vocal sounds more relax and transparent in my opinion.

 

AD8599 sound signature in summary:

Excellent frequency extension from low bass to upper treble.  It sounds very open and transparent with nice natural treble decay, more transparent than the stock AD8620+BUF634, Muses02, pretty close to Muses01, but still a 'TAD' more transparent than Muses01, which is very impressive.

As mentioned, vocal is a bit more laid back than the rest of Op-Amp mentioned above, in a good way, more relax, open and transparent.  If one prefers more intimate and forward vocal, Muses01 and Muses02 have more forward and intimate vocal compared with AD8599.

AD8599 Bass is excellent, extends very low, and has the most transparent bass.  What I mean by the transparent bass is bass with good definition and clarity.  Clear bass that never sounds muddy.  Mid bass punch maybe slightly less punchy than Muses01 and Muses02, but the bass is clearer, with better low bass.  Bass punch and overall quality is still better than stock AD8620+BUF634.

Imaging and spaciousness is best on AD8599, most spacious sounding in the group.

AD8599 also very detailed and revealing, so be careful with not so good recording, especially with bright and metallic treble, it might be unbearable with AD8599.  But with good recording, AD8599 really shines.

For example, listening to HDtracks 2013 Sampler, Cassandra Wilson - Another Country, is simply too too bright with JVC FXD80.  Patricia Barber - The Wind Song sounds alright, with moderate amount of sibilant, and the other 8 tracks in the album sound simply excellent.

 

What I like most from the AD8599 is the transparency and the sense of spaciousness, with excellent frequency extension :etysmile:

 

AD8599 is for those who like spaciousness and transparency.  For those who like warm and intimate signature, OPA2604 / OPA604 and Muses02 is better.

AD8599 might be more suitable with natural to warm sounding earphones & headphones, might sounds bright with bright earphones / headphones, so please take note.

Although JVC FXD80 I consider as having natural V-shape tonal balance, the treble with AD8599 is still nice, transparent, not too bright with good quality recordings.

Especially for classical music, AD8599 must be on the short list of the must try op-amp!

 

Those who has difficulty getting the Muses01, may give AD8599 a try :wink_face:

Highly recommended!

 

As shown in the picture, I fabricated a special cable and a switch box for the test.  

The DIY cable and switch box help me to quickly compare the sound signature without having to do too much unplugging and plugging of cables.

The cable is connected to the Balanced output (XLR) of Yulong DA8 (not shown), split the output into 2x Unbalanced output with 3.5 mm mini jack, connected to two Fiio E12DIY.

The 2 unbalanced mini jacks output is reverse in polarity, and I don't hear any difference between the 2.  This is expected, since the reverse of polarity is not between L & R channels in the same stereo pair, but between 2 separate stereo pairs.  Yulong DA8 has inverse polarity switch, so I can use it to hear the same polarity when switching between the 2 E12DIY, if necessary.

The bottom one is with stock AD8620, the top one is the one I use for Op-Amp rolling.

Agree on the AD8599, it is a must try for those who find AD8620 a little too shape. I think the AD8599 is probably the best sounding AD I have tried on E12DIY, matching that of ADA6427-1 and AD797 without much issue.

Anyone try the AD744 KN? A very nice op amp. Must be the KN.

Can share the sound signature of AD744 KN that you remember?

The difficult part is AD744 KN is single channel, E12DIY doesn't have much space to accommodate 2 single channel op-amps, especially DIP-8.

KN won't work on the E12DIY because it is single channel DIP8 (too tall with adapter). 2x KR (SOP8) should work for the same spec.

Buffers: LT1010, HA-5002.


Hi ClieOS, may I know where you get the HA-5002 please?  I think I bought a wrong HA-5002 previously.  I search DigiKey but not sure which one is the one.  Thanks.

seems the E12DIY provides a very good platform so you guys can find the best sound for yourself.

Mine come from Elelment14 (= Newark for those of you in the U.S.). Try searching 'HA9P5002' instead of 'HA-5002'. Intersil has a funny way of using a different part name from the name of the chip themselves. Remember to get the special BrownDog adapter as well.

We have you to thank for :D

 

I'll go as far to say E12DIY is a landmark for FiiO

+1

 

I found out too late about the DIY to pre-order but was able to source one from one of Fiio's distribution partners and it's waiting at the post office for pickup as we speak.

 

The concept of the E12 DIY is nothing short of awesome and once again Fiio has given us something special.

Thank you James and the rest of the team at Fiio, I continue to be impressed with your willingness to listen to user input to give us the toys we want.

 

I agree with ClieOS, the DIY is indeed a landmark.
