Same curiosity here... now waiting patiently till my Muses01 and Muses02 arrive from Hong Kong.  My friend helped me to order them from Taobao yesterday, hopefully will arrive next week.  Hong Kong to Singapore won't take long to ship.  I will share the impression of the two Muses once I have enough time with them.

 

Meanwhile maybe ClieOS and hkfriends can share some light as they have the Muses :)

You'll use the MUSES02 (min. +/-3.5V) when your amp can't meet the MUSES01's min. +/-9V requirement. Think of it as the next best thing and more oriented for portable / lesser power consumption  use.. While as good as MUSES02 is, I do find it on some occasion not as good as other opamp. But I never find MUSES01 getting outperformed in any situation.

Thanks for the explanation!

You have Muses01 as well right? Since FiioE12DIY supply voltage is +/- 11 volt, Muses01 will work in E12DIY right?

Have you tried?  Maybe with casing open if you cannot slot in the board :)

post #454 of 2221

Ordered the MUSES02 and will have it very soon, can't wait to compare it against AD8620/OPA1611.

post #455 of 2221

Thanks ClieOs for the suggestion...

I cannot believe I am now grinding this beautiful gold casing...:(

post #456 of 2221

I wanna know why people are opting for the muses02 over the muses01.

post #457 of 2221

Here are my impression over a few opamps in the E12DIY. I stuck to BUF637 this time and will look into LME49600 some other time.

 

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.

@ClieOS

 

Nice impression. May I know the source and iem you use for this opamp shoot out?  I find OPA1611 to be bright.... instead of dark... I tested with Fidelio X1, Heir 5.0, X3 as source

 

Currently using DX50 as source and MUSE01 ,I totally agree with you about the texture, it is really impressive

post #459 of 2221

The source are X3 (mostly) and DX50 (less). OPA1611 has some graininess on the top, so maybe that's what you are referring to? Brightness implies detail and edge to me, while graininess is just graininess, like roughness without the sharp edge, if that makes sense.

Thanks, ClieOS. It makes sense.

Did you mean LME49720NA?  

 

The NA is a dip8 while the HA is a round through hole.  Did you have the HA on an adapter?

I do mean LME49720HA (TO-99). Of course, I have it on a DIP-8 adapter and the case is opened.

i wonder how different the HA and NA are...if any

post #464 of 2221

I have the NA version as well, but they are in my other amp and I don't want to dismount them. I did a side-by-side A/Bing before and they do sound the same to me.

Thanks for the input.  

 

I rather not have to hassle with soldering if I can avoid it
