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.

George, you keep saying the same thing, and getting the same response. I'm sure most of us have done this. I used to own a "good" R2R dac. I was not amazed. I prefer my current delta sigma dac.

Good for you Ross, stick with vinyl it's more your speed
R2R sounds more like vinyl with the rolled off high frequencies it's  probably why you like them .
