Comparison of latest DAC chips


I own a Bluesound Node 2i which greatly improved sound after I added the Cat 6 cable.  I do not own a separate DAC but am told it would be the next step improvement.  I have done enough reading that it appears the two latest chips are the Sabre or ESS ES9038PRO and the AK4499.  The brands I have looked at are Sabaj d5($469) and a Topping D90($699).  I saw a great review on Audiocircle of the Sabaj D5 which is now a year old.  The Topping D90 is newer and I hear the build quality of the Topping as well as customer service are both better.   Other brands cost more and most don't use these new chips. 

Is there a difference in how these chips sound?  I would appreciate any comments.

Thank you kot.  My D90 is arriving today.  Have you tried the different filters? 
Congrats Dale.  Let us know how it goes.  With a 30 day trial period from Apos, you can't lose.
@daledeee1   as far as filters I ve been using whatever  default values there are ...Have not played with them extensively

I got the D90 hooked up.  I already had good sound stage.  This thing just adds more.  No drifting of image, more air with wall to wall sound. and at times(depending on recording) I felt like I was in a holographic sphere of sound.  I opened my eyes to make sure where the speaker sits.  Everything just sounds rich and beautiful. 

When I got it I could not get it to turn on.  The manual is a rough translation and could use some work.  It will not power up unless there are interconnects with signal going through them.  Also, the instructions are backwards for the voltage setting. 

So far, everything I have done to my system has been a step up.  The next step would be very expensive and I will sit right here for awhile.  Famous last words. 
@daledeee1 It does not need a manual.. Any audiophile worth his/her salt will figure out its menus, the menu is very simple .....
It will turn on without interconnects, you need to to turn the AUTO setting OFF from the MENU option....

I suggest give it at least 250 hours of break in with music (not just keeping it plugged in) for "serious" evaluation.... But even right out of the box that thing is something extraordinary one can tell !!! AND FUN!!!! Enjoy !
