i am new to this dac. so my quick look at the guide, i think can use 5 separate psu:
- 3 separate psu for 3 trident
- and 2 separate psu for analog section.

anything else?

is there any information on the current draw of each section? as i would like to supply with CLC raw psu only to each section. any possible problem by using unregulated raw power supply?

thanks
erwin

Do I ground B4 to the chassis, VG on the Sidecar or a ground on the external I/O connector header?
I suppose pin 3 GND of the external I/O connector, Russ or Brian could you confirm?

Yes GND at EXT-IO which is the same as VD GND or any of the power GNDs.

It's necessary to change R1 10K in Sidecar for R1 1 K in Sidecar?

It depends, if your driving it from ~5V the 10K will work fine. If your driving it from an LED spot (1.8V) you will definitely need something around 1K (even a bit less is ok)

It is correct except that B5 should be B4.

Would it not also make sense to turn off input remapping (B7) when sidecar is switched to i2s?

No - for sidecar you would just leave it on.

You could switch it off for SPDIF, but it is not necessary.
