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.

Just rejecting your preposterous statement that all R2R dacs are inherently better
Didn’t say "all" sunshine, I said the better hi-end ones, now your generalizing, with that "preposterous statement".


For those interested in what the better hi-end ones are that are R2R Multibit here is a list, it’s about a year old now, there are even more now and even better ones to add to it.
Trinity Dac
Ypsilon Cdt-100
Phasure
MSB Platinum
Total Dac
Audial (Peja Rodgic)
AMR top dac and cdp (Thorsten Loschec)
Exasound
Reimyo
CH precision
Holo
Denafrips

This is the reason why R2R is better, Delta Sigma can only give you a facsimile of PCM, where R2R Multibit is bit perfect.

MoJo Music quote:

" When a PCM (redbook) file is played on a dsd, sacd or Bit Stream converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit delta sigma DACs do a poor job of decoding PCM.

@georgehifi : which Exasound DAC is R2R? I've never seen one, they're all ESS.

Don’t know abraxalito, got that list from someone else they sent me, didn’t bother to check all of them.

Also can say all the MSB’s are R2R Multibit save for the very first 1999-2000 LinkDac models that used bit stream Delta Sigma PCM1738-32’s then went discrete R2R in 2003 with the Platinum LinkPlus and never looked back at Delta Sigma again.

So the better ones are ... better. Can't argue with that logic.
