The HD 598s have an excellent soundstage. One of the best in their class. But, to reproduce a good soundstage you must have source material with a well recorded soundstage. 
 
Find the right music material and you will find your soundstage.

so what Dac you recomend for the a better soudstage ? beetween 100$ -250$

The DAC does not determine soundstage. The music material determines soundstage. 
 
You need to listen to MUSIC recorded with a good soundstage. Jazz and Classical are often recorded with excellent soundstage. Rock and Pop not so much. I have no experience with "modern music" . I listen to Jazz, Blues, Classical and classic Rock.

 I assume you are listening to the CD, not Youtube. As such, I have no answers. Sorry.

Soundstage is all about the recording and the headphone design. Let me take a guess here.
For the sake of conversation, let's assume the recordings or source is fine. I have a pair of Senn Hd518s which, as I have learned, have the exact same drivers as the HD558s and HD598s. The only difference is subtle design tweaks. The HD518s do not have the extra piece of foam or whatever over the driver, however, like most Sennheiser headphones they have a warm sound overall. In fact, if you graph the HD518s you will see that they fall off a cliff at about 9KHz and then slowly start to pick up again at around just after 10KHz. The same is true for the HD598s, however they fall about 4dB less than the 518s. In contrast the 518s extend about 3dB more in bass. The HD598s do graph a bit better overall however. Like the HD518s, the HD598s are good headphones.
That said, the staging performance on my 518s is good and I can imagine same or better on the 598s, but a bit narrow. Sennheisers also tend to be tuned towards the warm side (with the exception of the HD800s perhaps), which can give the feel of a somewhat narrow soundstage, but intimate presence.
So I'm guessing what you looking for is a wider soundstage? Am I correct?
 
If that is the case, no dac or amp or cable or what have you is going to change the staging on your 598s or any other headphone. Again, it lies solely in the recording and / or headphone design. Just for reference, AKGs are reported to have very good and wide staging.
 
I found all this out in my recent search for headphones as an upgrade from my 518s.

Soundstage is about the varying echos among the instruments and vocals. Also if a stereo recording some sounds will be more to the right or to the left. Much talk about soundstage is BS.

I have a theory your HD598 isn't impressing you with its soundstage because its strong mids sound close and in your face and kind of block out the sounds farther away. 
 
Regardless, the file you linked is not a very good example for soundstage.  For whatever reason, it sounds a bit closed-in and lacks separation.

This video is not invalable , you  have onther one ?

I have the HD 518, the sound stage is there in some recordings. It's a little short arround 1kHz and therefore sometimes it feels numb. Maybe you can try some EQ-ing just to hear if the soundstage changes for your type of music. I'd suggest at arround 1kHz, slight boost.

hd 25-1 sounded better and had more soudstage than HD 598 , i will try to buy the HD 800 and HDVA 600 dac in the future

The only music that sound better on my HD 598 better than HD 25-1 is this https://www.youtube.com/watch?v=M3z6XCug_W8 , i think i need a better Dac
