I have nothing to do with the people that are making this. I just ordered off Ebay and I wanted to share the results. 

 

Order placed. Thank you for your impressions :D 

I got the 'dual' versions of that opamp from him (used in the soundcard, and sounds fantastic).

Man, 3 years ago I was perfectly happy listening to a stereo Bluetooth headset through my iPhone at work. Now I'm $700 into headphones, amps, and DACs and I keep thinking about what I should try next. I liked it when things were simpler. We have to go back, Kate!

The soundstage opens in width and depth and height to an almost limitless size. I have some good tube amps sitting here including the WA-2 and it cannot produce the incredible soundstage I am hearing with these opamps in the M Stage. Not only is it huge but the placement of instruments is extremely precise with incredible layering. I am listening on T1's so lesser headphones may not get all of this. Tonal quality is very realistic with the ability to see through the music. Transparency is astounding. 

 

I have been a tube guy all my life and I have owned several solid state amps always searching for the one that would bring me the same kind of magic I get with good tube amps. The basic M Stage is very good but the WA-2 is better in almost every way. Now with the addition of these opamps the little M Stage gives the WA-2 a real battle and beats it in total soundstage presentation. I would not have thought that possible but the image through the M Stage with this opamp set is positively 3D.

Hmm this sounds really tempting. I could always use more soundstage, although a DAC upgrade would get me some of that. What DAC are you using?

 

EDIT: Actually, never mind. Apparently the LME49710 is the single version of the LME49720, which is very similar or even the exact same part as the LM4562 which I already have. I still need a new DAC though :)

I have the Yulong D18. It's a $700 dac direct from China. According to my own experience and the reviews on this forum it competes very favorably with dacs up to $1500 and beyond. I totally believe that the dac is a factor in the results I am getting with the Matrix. You also have to consider that I am using $1400 headphones. I cannot guarantee the same results with lessor equipment. For me, the results with this opamp switch have been substantial. I really think that this companies implementation, the way in which they create and mount their custom adapter is important to the use of those particular opamps. I have doubts that you could just stick the opamps on any browndog and come up with the exact same results.

 

For the first time with any amp I have owned the amp gets completely out of the way and does not impart it's own house sound on the recording. Every amp I own and have owned has some sonic signature that follows each individual recording. Now this Matrix totally transforms itself depending on the quality and mastering of the recording. That to me is the definition of neutral. I have not heard any amp do that so convincingly before.

Nice! The D18 doesn't have its own headphone amp section, right? It needs to be paired with an external amp? I'm thinking of getting the D18's little brother, the D100, which has an excellent headphone out that's apparently almost as good as the M-Stage.

Just to clarify could I get 2 of these from TI( http://www.ti.com/product/lme49710#samplebuy) and put them on a DIP adapter (ebay) by squeezing them on (like this)?

If you are using the same part then you should get the same results. If you look at the photo of the one I bought you can see that the opamps are not mounted on a dip adapter. The little pcb was specially made to accept the opamps directly soldered to the board. I am not saying that makes a difference (although it might) only that it is a lot cleaner with a more solid connection. Of course, you can build your own connector with the the same opamps and expect the same results if it is put together as well.

 

Certainly tempted to buy the opamp and just be done with it, since I have some adapters and can get the opamps free, figured I'd go that route. cool.gif. I'm just not super well versed in opamps, and wanted to make sure there wasn't anything too wrong with my approach.

For $700 you get just a Dac. No headphone amp no usb input. I use an M2Tech Hiface 2 for the input. I have heard that the D100 is well reviewed so at that price level it should offer excellent performance.

I totally agree. If you can get them for free and you have some adapters go for it! Free is always good. I bought their setup because it was well made and just pop it in. I can't speak for how much their special adapter effects the sound. I can only report on what I hear.

Glancing over that ebay seller's items it looks like they have a lot of adapters and opamps they have made. It's actually pretty impressive, and they somehow make a pcb look pretty good. Definitely a good price considering how much work they go through.

Folks, I hope no one is getting confused by all this stuff, but the LM4562 is a direct drop in replacement for the stock Op Amp in the M Stage. No adaptors needed! Nice and easy! :)
post #4255 of 4904
Yep, the LME49720 and LM4562 are direct drop in replacements. LME49720 is essentially two LME49710s. If you get the single LME49710s then you need two of them and an adaptor.

I have one of those myself actually, and my orignal selller enjoyed the Lme 499990 better, as it had more realism over all. Where the Lme 49720 was spacious with amazing treble and mids, the Lme 49990 was equally spacious, with slightly less treble air but better defined bass. 

 

So honestly my Matrix has already been upgraded with an aftermaket op amp, the LME 499990 which fits along with all the OP amps you guys have recommended. In addition the Audio GD 10.32 would be a cheaper upgrade than one might think. As an eays $300 combo sale of my Matrix and oDac would easily pay for most of the price of the new amp. And best of all I've been in need of a DAC with two RCA out's [the Audio GD 10.32 has just that.

 

So for me The step to logical, and the use of SE cans with a Balanced Amp is a cheap upgrade and one my Desk would greatly appreicate me to make!

Just curious, what's the attraction of balanced amps?

I don't see the point, unless the design is used to cancel distortion or cancel noise or both.

A lot of designs seem to do neither. They are jsut on the bandwagon and are milking the marketing of "Balanced!"

I feel the same way about re-cabling... just my opinion...

I'm very contrary in some ways.

 

I argue that if you think cables are snake oil (placebo, etc, etc) then you may as well just say that Op Am rolling is snake oil...............and let's continue...........tube rolling is snake oil.

It sounds odd...........it sounds illogical.   Replace one 6SN7 with another 6SN7.....and your tube amp sonds different?   But they are both supposed to be 6SN7 tubes, i.e. the same thing!

Feel free to disagree.  I have no real problem with that.

Anyway, this is on topic, as we often talk about Op Amp rolling in the Matrix M.

balanced setups are more immune to interference since the the two opposite phase signals (which will be affected equally by interference) are combined to create the original signal. this allows amps to provide more power at a lower THD (which is why you see on a lot of balanced amps the power output from XLR is higher than SE).
