forgot to mention mine is also doing this. Really solid without any distortion or pops. Wish there preamp would cut off if the headphone was plugged in, but I found a work around. Sounds great with my Airmotiv 4s

Oh... Awkward. I think I have the earliest version. Maybe it was implemented later? Either way, I found a work around that's pretty efficient for me.

I got mine about 8ish months ago. Not sure about revisions done before.

I using the M Stage too, to preamp the PC speakers I have (Microlab Self amplified), and mine it's from August 2013 and it has the RCA cancellation headphone jack too.

By the way I'm really impressed because it works very well like preamp for speakers too, and nobody had speak about that... and even in the Matrix web there aren't soo much information abut the rca outs to know how it works as preamp....

 

I have the LM4662NA opamp in the DAC section and the Class A Biasing OPA627AP on the Amp section but some time change to the stock OPA2134PA because I like it very much with my bighter headphones (K701 and HD668B).

 

I think it's really impresive the new DAC section improvement and not raising the price soo much, it has a better USB system implementation that will increase the capabilities from DAC and the better of all it's now it gives you native ASIO support!!! 

 

Matrix has made a good job improving the DAC a bit with no raisng the price. If before was good now it's even better DAC/AMP...

 

What will be the new improvement... maybe a Balanced headphone out... ??? :wink_face:

Thread Starter 

I feel bad because I've been calling this amp "the M-Stage" all this time. Technically M-Stage is the series which features the HPA-1, HPA-2, and DAC. It didn't matter at the beginning since there was only one model in the line. Now that we've got a few to choose from, I should probably start using the proper terminology. 

 

Anyway I spent a little more time with the M-Stage HPA-2 (See? That wasn't so hard...) using the USB input from a MacBook, and then line out to high-end setup of AURALiC Taurus mkII and HiFiMAN HE-6. Obviously the built in DAC is not a substitute for megabuck designs or even the really good $800-1200 units out there. Duh, right? Nonetheless, it doesn't sound terrible at all. It does "the basics" rather well. There's no grating top end, muffled midrange, dynamic compression, or any of those types of dealbreakers. Which are pretty common in budget DACs. It doesn't have the same realism or transparency like you'll find in a Yulong D100, Resonessence Labs Concero, Parasound Zdac.... but it isn't all that far behind either. Thus far it seems to compete well with dedicated budget gear like the Audinst HUD-mx2. Which is pretty good considering this is just an "add on" feature.

I currently have this op amp and would like to try a more neutral one. which one do you suggest?

LM4562

Is this the correct one? http://www.mouser.com/ProductDetail/Texas-Instruments/LM4562MA-NOPB/?qs=QbsRYf82W3EF3n1VJV%252bowQ==

 

Any other website I can purchase this from? and I only need one right?

You need LM4562NA.

The part you show is incorrect as it is a Surface Mount chip.

You only need one.

Whats the difference between the two?
post #4530 of 5031
I haven't heard the LM. I've only had the stock and the LT1364 recommended to me by Athur of Matrix USA. It's less dark than the stock, but not harsh in treble. Works very well with HD800.
