Is there any provision for USB input which can be added later?OR any USB adapter slot on PCB?

You must provide your own usb->i2s interface.

Thanks,
I just read about some comparison between Sabree DACs-
ESS ES9023 Sabre Premier DAC with integrated op amp

A review of ESS's DAC lineup is interesting (numbers are for 8 channel mode on the 8 channel parts):
start with an unbuffered voltage output and shared supplies
9023 - -94dB THD, 112dB DNR
buffer the voltage output, separate analog and digital supplies
9006 - -102dB THD, 120dB DNR
switch to 64 pin package and add more supply pins
9008/9012/9018 - -108dB THD, 120dB DNR
go back to 48 pin package but change to current mode out
9016 - -110dB THD, 124dB DNR
keep current mode out and switch to 64 pin package again
9008 - -118dB THD, 128dB DNR
do some die layout improvements over the 9008?
9012/9018 - -120dB THD, 129dB DNR

So is that ES9023 has more distortion level than older chips on paper? with only 94bd THD compared to other chips?How can be a true performance in real world?

One question-
Is ES9023 better than other Sabre chips?The sound quality comparison?
ESS ES9023 Sabre Premier DAC with integrated op amp

THD is 94db compared to rest(around 102-110db).

If these are your questions you likely have some reading to do before deciding which DAC to build to meet your objectives.

ES9023 is 1/20th the price of the ES9012 for single chip.

BB sometimes are laid back,ES are perhaps better performer.

Hi some people even think ES9023 sounds better than some ES9018 implementations. I don't know about that, I can only tell it sounds way better than it should. For instance AKM chips are no comparison.

The same technology that is used in more expensive ESS chips is used in ES9023.
