ESS Sabre ES9038Pro to be used in Ayre's new QX-5 DAC.

Now I can only speak in generalities and I have not heard the latest crop, but I found the earlier generation DACS like the ubiquitous Burr-Brown PCM1704/1792 and the AKM 4397s as implemented in MY APL NWO-1 and select Esoteric DACs and players more musical than other implementations of the ESS Sabre DACs. YMMV.......

Based on what I know on both the ESS 9038 pro, and the AKM4497, the better chip will be based on the application. Also on personal tastes. The ESS chip has several technological advances to clean up jitter, and make it more immune to dirty power, board layouts and all of that. It also has the ability to customize the filters. It's also a much better performer technically. It's a more advanced chip, and it's going to cost several times the price of the AK4497.
The AK4497 has a 1Bit DSD bypass mode. So if used with an external upsampling engine such as HQplayer, it has the advantage of being able to bypass the internal SDM/SRC algorithms. AKM has also put much more effort in making filters that sound more natural and tube like. The "Velvet sound" filters. Based on hearing the AK4490 in a very good implementation, they do sound very nice.
No matter what chip is used, these 2 chips are by far the best SDM chips we have seen yet. IMO they are going to put an end the recent resurgence of R-2R DAC's
So has anyone designed DACs with the ESS 9038 pro or the AKM4497?
I'm sure every manufacturer out there that is currently using an ESS chip has plans to use the new chips. So far the only one that has announced using it is Ayre with the QX-5. There's also a new Sabre chip called the 9028 pro. It's not near as good as the 9038, but it offers the advantage of being a direct drop in replacement for the 9018, without re-engineering the DAC. So I'm sure tons of DAC's will be using it.
So does this mean one could literally pull their 9018 DAC chips out of their DAC/player and plus in a 9028 pro, or is their more to it? What would one expect from such a replacement?

So do you think existing product with ESS9018 DACs will survive the test of time or will they be irrelevantly e-wasted and forgotten about in years to come?
I find this relevant to the future fate of their next generation also, possibly the consumer treatment of DAC values in general...
If that is the case, there is probably no market future for high value DACs and digital stacks.
.hat could result in a common chip SDK in all brands without implementation variation....?
From what I understand yes. If you know how to drag solder SMD chips, anyone should be able to upgrade their DAC.
