This PCB is told to be co-develop with the ESS engineer and tested with Prism Sound dScope Series III with excellent result and better than USDxxxx DAC

but the decouple capacitor distance to the es9018 is very very long and narrow trace, any body has any idea on it?

Yep, the decoupling is creepy.

But hey, who cares of it as long as there is 4 layers gold plated PCB with yellow cute silkscreen?

basic layout, nothing special, second the decoupling. As to the rest, marketing...
In fact some ESS published designs look better.

4 layers and they did THAT!? has anyone there not heard of power planes? the clock trace is stupidly thin as well and fairly large vias in all of the i2s traces?. its so huge! power supply looks ordinary, the LT are OK, but easily bettered, again someone expecting that ICs are good enough for everything.

the J-test is crap, the crystek does not have close in phase noise anything near that good.

-150db... I dont think so, try -100

one interesting thing though, they may be the first retail outlet for the ESS dac chip
