Maybe this is a bit offtopic, as I don't own an M-Stage, but I do own a Cube which has socketed opamps (OPA2134 in the I/V stage and LM833 in the heaphone amp). I'd like to roll opamps on it, so would that LM4562 be a good choice to start? I guess, like in the M-Stage, it'd be a straight swap...

I agree with Chico The Man.
Spending big bucks on variations of the OPA627 is a waste of $$$.
For $3 the LM4562 is one of the finest Op Amps you can get for audio use.
It is a direct replacement for the stock Op Amp.
As a pre-cautionary measure, I would operate the LM4562 at a gain of +10 dB or +18 dB.
 
I do not believe that you can return used Op Amps to Mouser.
I think you've baked the OPA627 but I do like your Avatar

 

Hehe thanks for the suggestion. Got an LM4562 instead

Haha.  Replace the guy in my avatar with an opamp and that's what happened

Yes the OPA2134, LM833 and LM4562 are pin for pin compatible with each other.

Thanks. I'll try to get my hands on some samples of the LM4562...

Thanks for the comments everyone, I appreciate it. Writing a review is hard work so it's nice to hear that my work is helpful and/or enjoyable.

As for the question about the Beyerdynamic DT990s: I do own a pair, and I have used them a bit with the M-Stage. It seemed to do a very good job although I didn't critically compare different amps. Note that my 990s are the 600ohm version, which is very different from the other 2 versions. But in my case, I find the M-Stage to give them excellent bass authority, smooth clear mids, and fairly extended but still relatively relaxed highs. Excellent dynamics. I guess you could say that they retain their characteristic sound signature, which is what I usually want an amp to do. You definately don't want an amp that smooths or recesses the treble energy with the 600ohm DT990s.

Hope that helps.

Thanks, that helped me decide on buying the m-stage because i own the DT990/600 version and am going to buy the Q701's very soon do i need an amp that can do for both! just what i was looking for

Good choice!
I own a Matrix M Stage,  DT880/600 and Q701.
The Matrix has no problem driving either headphone cleanly to any volume you would want.
The M Stage even drives my 2,000 ohm Sennhiesers!

I am thinking about buying a Matrix m-stage USB version, just wondering will the change of OPamp void the warranty of the amp

 

[Chris J]

Matrix vendor Tam Audio sells Op Amps for the Matrix M Stage, I guess the implication is that Op Amp rolling is OK and doesn't void the warranty.
You could always try e-mailing Tam Audio with your question.

Does anyone have any issues with 600ohm beyers distorting with anything above 0db gain? No matter what i set, there's huge bass distortion

No,  I've used them at 0 dB, 10 dB and 18 dB of gain on my M Stage with no problems.
I normally use my CD player as the source with output of CD player set to -5 dB (0 dB is full output).
I'm using DT880 600 ohm.

believe it or not, swapped over my 1/4" adaptor with one off my sennys - issue gone!

Well M-stage and Q701 are a great combo and I just ordered them my self. I have read tones of reviews pairing the two and all braging about the great results. dont know about the others though

I just thought of something, what if I put my Xonar ST output volume at a lower level than normal, lets say 40% and switch the gain from 10dB to 18dB on the Matrix, wouldn't be better for getting more from my M-stage amplification instead of Xonar's amplification?
