I can't comment on the 49990 but I can say that a simple opamp swap is extremely easy. I was a little concerned but all it takes is a screw driver to remove the top of the m stage and then you just pull out the old one and stick in th new one. No soldering required. For the couple dollars these things cost it's worth a try.

True

M-Stage owner here with LM4562 opamp... also very pleased with how it pairs with my Annies and MDs.

Was previously going to buy M-stage, but I will say after pulling out a bass slanted but muddy mids opamp from my altoid and swapping in a new LM4562 , the difference in mid-separation and treble detail has been great so I'm also a LM4562 fan as well.
I made sure I got mine from a reputable seller vs getting a dire knock-off from China/Hong Kong being passed off as a LM4562 ruining my entire audio chain.

The best would be to order a free op directly from Texas Instruments.

Has anybody tried both Asgard 2 and Matrix M Stage?
 
Which is:
 
1. Faster and with better PRAT
 
2. Cleaner and clearer?
 
3. Crisper and sharper?
 
4. With more forward mids?
 
Can somebody please help?

Where is the best place to pick up a LM4562?  I'm curious to try it out as well.
 
I saw this seller on ebay:  http://www.ebay.ca/itm/LM4562-Dual-HiFi-Audio-OpAmp-AUTHENTIC-LM4562NA-DIP-8-/160496917340
 
Seems legit and has good feedback.
 
It would be $3.75 + 3 shipping.  Is $7 a good deal with shipping for this opamp?  Any better places or options?
 
Thanks

You can order a free sample here: http://www.ti.com/product/lm4562

Ordered mine from a seller called "nooelec" from ebay. They stated it's a legit one. I sure hope so. Also getting a Muses 01.
 
Edit: I ordered from that seller. Didn't notice you had posted a link lol.
 
I sure hope the Muses01 is atleast authentic if anything.

What's the difference between the 4 versions? (Only 2 have free samples). And is this one of those types where you need 2 + an adaptor? I've never swapped opamps before.

 

[WEeziel]

To my understanding, if it's in dual, you only need one. Swapping opamps is very easy though.

 

[blueangel2323]

So the NA version is the dual? What are the other three? That TI website is so technical, I don't understand a word of it 

 
EDIT: Actually, I just read that the LM4562 is dual-only. So I still don't understand the difference between HA, MA, MAX, and NA 

 

[WEeziel]

I suppose it is. I ordered the LM4562NA which is DUAL according the ebay listing.

 

[bracko]

It is NA version you should order. That package type fits into the Matrix amp. It is also a dual amp, compatible with the stock one.
