I finally got my black knob in the mail, today.
 

 

 
 
Looks good! I mean, the knob not the picture quality. 

 
I think that is a much better looking unit overall than the tiny little guy. No troubles with the install?

Yea, I'm using my phone lol
 
No trouble to install at all. Just remove the little screw on the original with a hex key... remove old knob... line up the new knob appropriately along with the screw it comes with... and screw on with a small flathead.
 
You do have to paint the small circle, however, because the indentation comes unpainted.

Thanks for the replies LCMusicLover, hifimanrookie and Chris J.  I knew I had read about someone else having the same experience but couldn't remember how many pages back it was.
 
Nice to know I'm not crazy and especially that there isn't an issue with the amp.

 
Actually, I do think your crazy! 

 
Hey, I kid! I kid!

Yea my opamp arrived rather quickly, too. I can say it took approximately 10 business days for my knob to arrive.
 
It is coming all the way from China, you know

It took mine closer to 30 days to arrive, but it was worth it, love the knob.

Got my Matrix M stage about a day ago, I've left it on, see if it opens up.  I like what I hear so far detail and transparency are better than anything I've owned so far (desktop amp newbie), but for the price I think I like it better than my 3G Arrow so far.  I got the black knob too, hope it comes faster than 10 days...

How are you guys getting the stock knob off? I tried my 1.4mm and 2mm allen wrenches, the 1.4 is too small, the 2, too big, and these are the 2 smallest of my allen wrench set.

 

[Taowolf51]

Have you tried an allen wrench set with imperial units?

 

[Maxvla]

I don't have one. I assumed it would be metric being a Chinese product. The ones on the face plate are 2mm. Guess I'll head to the store tomorrow and see what I can find.

I've noticed Muses opamps have been getting some attention with other amps. Has anyone tried any one of the Muses8820, 8920, 01 or 02 with the m-stage?

Went back to the LM4562 opamp instead of the opa627 bias adaptor. Sounds good.
 
Why use two opamps when one can do the job...  If the amp was dual mono then it would make more sense. 
 
The opa627 are the best opamps I've heard (used them in other amps, including my Audio gd) but they're not going to be optimized using them in such a configuration as in the dual adapter for the m-stage. Your just paying for the hype of 'opa627' when buying the class A mod. And as far as I've read up on this modification, you may well be stressing the amp by using it.
 
Its hard to a/b when changing opamps but I do think the LM4562 is the better sounding option after trying it twice now. 
 
imo

It needs a 1.5

I changed the opamp to the OPA627 with the Class A mod. It's hard to tell if there's a change or not without having a stock M-Stage next to it to compare.
