Looking at the advertised THD+N for the DAC chips themselves to give a lower bound:
Code:
ES9038PRO: -122 dB
ES9038Q2M: -120 dB
AK4497EQ:  -116 dB
AK4493EQ:  -113 dB
AK4490EQ:  -112 dB
I guess AKM are a bit behind ESS in this area (or more honest), but it looks like switching chips makes Topping's life a bit harder in terms of improving SINAD.

The incorporation of XLR should help in this figure as well though, correct? When implemented correctly, it potentially lowers noise right?

But with no "ESS distortion hump" on lower levels, most likely.
Like the first generation DX7 based on mobile ES9018, or the SMSL M8 compared to the M8A.
I wonder in which area these newer mobile ESS DACs are superior to the older ones. Cost maybe, or ease of implementation?

So, anyone pre-order yet? Think Amirm would like to review it?
Topping spoke of like March release as far as I know, can take a while. Also Topping sent Amir review samples so far so I'm sure there will be a review sooner or later :)

If you mean D70, no I don't have any review samples and don't expect any until next year.

For that price ~$600, I could find a bunch of DAC from Chinese manufacturer with dual or single AK4497 or ES9038PRO or ES9028PRO.
Gustard A20H, X20PRO
XRK U10
SMSL M10
and weiliang or some cheap brands.

@peterq we don't really know how any of them perform though :/ plus this one is named to be superior to D50 which is exciting :D

Yes, none of them has measurement and you can only find some user(or seller) reviews from some Chinese forum. I think none of them did EMC or other hardware testing during development. If I need one, I definitely go for some reputable brands such as Chord, Apogee, oppo. Some devices with the latest DAC chip can perform well during testing, but we don't know it's reliability and the quality of the product.
