  Compared to stock. Honestly it has been so long since I tried the LM4562 I can't recall. I just remember when I tried the combination I suggested it hit my sweet spot and locked in what I was looking for. I did not carry it any further as there was no need. I will warn you that no opamp is going to turn a $300 amp into a $2000 amp. At the $300 price point your risk level is very low. Everyone hears differently  and my experience is listening to mostly classical music. All I can tell you is that I have 2 tube amps and I have added the Auralic Taurus and the M Stage is not in the league of the Auralic but not completely embarrassed with the HD800's. That is high praise for the $300 M Stage.

Which way do you put the LM49710HA in? Can't see any markings to tell the tale. [Like with the LM4562 - there is a tiny notch in it, like with other conventional op-amps]

From memory, because I don't want to open mine unless you are really stuck, the indicator is on the silk screen (printed image) on the top.

Ok thank you.
In case I am stuck I'll come back to ask you

Once you burn it in let us know what you think.

Will do but I just ordered it so it's weeks away

EDIT: I own the new HPA-2 but since the amp section is identical mos likely, that shouldn't be an issue.

The ride was fun!

Which is why I want to get the Matrix Quattro balanced headphone amp!

I think a picture would be much obliged.
I'd rather be safe.
Thanks!

Sorry for the late post I just noticed this. I sold my M Stage since I have the Auralic Taurus so no photo. The white dot (circle) printed on the top is the indication of the notch. Just use that for your reference.

K, thanks!
That's what I've planned.

Would anyone have any idea why nothing comes out of my Matrix M-Stage to my headphones? Its like it just died for some reason. Ive checked the cabels, no problems. I have set my music player to pass the music through my S/PDIF port, I have PCM enabled in the xonar dg panel, but nothing. It worked fine a week ago, but suddenly it just died overnight. Im not sure what has happend. Any ideas what to check or what to do? Headphones work fine without the amp.

Is the right input selected with the switch on the front?

 

[WEeziel]

Tested both input, none worked.

I'm wondering if the M-stage can drive the AKG K340 eletrostatic-dynamic headphones. These are 400 ohm and 94 db so very power hungry. I'm currently driving them with an Emotiva speaker amp, but would like to get an office setup as well. Does anyone have relevant experiences? 
Alternatively, if the m-stage can do justice to 600 Ohm Beyers, it could indicate that it's also good enough for the 340s.

I have no direct experience, but I suspect the answer is no, it will not drive K340s.

But it easily drives 600 Ohm Beyers. They don't really take that much power, approx. 1-10 mW.
