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.

Yes merosen that is the seller but I got an email from them a couple of weeks back and they had it on sale for $1499
Just a follow up the Denafrips Pontus and the mhdt Orchid and Pagoda were some of the DACs that the Lotus 5 beat hands down.
The Hans Beekhuyzen Channel "Quite often I see people seeking for the cheapest digital to analog converter using a given DAC chip. For they think that the DAC chip is the only factor influencing the sound quality. Well, they couldn’t be further from the truth…"

Thanks very much for the suggestions.  Since I never owned a DAC can anyone explain R2R, multibit, or anything else that applies.  So far the D90, Denafrips(backordered at least 8 wks) and Sabaj D5 all look good at a reasonable price.  I have a Schiit amp but don't know if a DAC from them would match the three above(at comparable price)

Also, I started out at ASR but found some threads that talked about numbers but don't even mention sound characteristics.
