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, all of your quotes are about recording in DSD. They say literally nothing about DACs. They certainly don't support your conjecture that delta sigma chips "do a poor job of decoding PCM". You will need to come up with something else.

If you can take in what the recording people are saying and work it out, there's no hope, over and out.

The "recording people" are not saying what you think they are saying. 

I think you have read that Mojo Audio web page without fully understanding it.

Uh, yes most recordings are n PCM, what type of modulator do you think they use when they are making these recordings?  For example what do you think a TI PCM Audio ADC uses? They use delta sigma modulators.

Just have a listen to any PCM redbook 16/44 24/96 or DXD through a "good" R2R dac and be amazed, then play the same through any Delta Sigma dac and hear what you get, it’s a yawn.
