Yes, the user manuals, and FCC certification enclosures/documentation indicates TRS outputs. Nowhere in the user manual (or from internal photos) is there any indication of, or facilities for DSP. D90 III, different story.
I'm more than satisfied 3 years on with my $750/used (AK4490) RME ADI-2 DAC FS

If the translation is correct ,PEQ will only affect USB and will possibly run on an app on the computer's/phone's side,like the interfaces do.

Will the EQ be stored on the DAC so that you could plug it into another computer and still have the EQ active?

Depends where each profile (it says you can have multiple) is stored.
Judging by the MCU's limited storage I would bet they will be stored in the computer's side.
So...

Thinking about it a little more,it's 192Khz/32-bit limitation can be a tell that each selected profile is stored in the device as there would be no reason to limit it if it was on the computer's side.
Computers can do a lot-lot better than that.
I think so, but im not sure.
Maybe 1 profile in dac and more can be saved on pc side to be uploaded when connected

Onboard storage, of course.
Will PEQ add perceivable latency?
Tambaqui is not a 1-bit dac.
I am quoting Bruno Putzeys here:
"The Tambaqui sits more or less in this camp: the PWM signal has a switching frequency of 3.125MHz, and can take 33 discrete lengths from 0*10ns to 32*10ns. So it's basically a 5-bit, 3.125MHz converter. The choice for PWM was given by the need to get rid of those idle tones I mentioned."

You can also read why he developed a pwm dac rather than 1-bit dac or a ESS/AKM based dac.

Balanced stereo is still only 2 channels, not 4. And unless you can apply different PEQ to SE and balanced outputs, which would be unusual and notable, it's still only 2 channels.
I mean channels of amplification. Balanced stereo requires 4 independent amplifiers
Yes I know, but we see more "lanes" on the D900 board, so it coud be several 1-bit streams added together (which is what the Tambaqui is doing with 33 of them - it is an original take on the PWM DAC idea - note also that only one is changed at a time with a clock of 32*3.125 = 100Mhz).

That's probably where DSP is and the reason why is tied to USB only:
But Is it still the case in PRO sabre series? According to manufacturer it is not:
ESS Sabre Reference DAC (8-channel)
It works! Anyway I am listening to Hilary Hahn NPR Tiny desk concert now with a big Not only I can listen to my es9018 now by in the process I have learned how to talk to chips using I2C. This will be very useful when I use Arduino to control the es9018. It’s ‘a process’, isn’t it? :p...

You still do not know how it is designed and you already judge it?

The XMOS can receive other digital inputs, not just USB. Limiting DSP to USB would be a design choice, not an XMOS limitation.

So what other reason could it be?
Reserving it for the bigger models?
They do stare that D90 III is DSP'd on all inputs.
