I tell you what though, nothing beats not needing to drive a long cable to your dac in the first place.... just use an isolator and reclock locally at the dac if you can. people really shouldnt be treating this like a separate peripheral, its part of the dac, it should be as close to the dac as possible, you should not use one of these HDMI or teleporter things just to enable you to install it somewhere you have enough room for your shunt regs... the thing is tiny, you should have room for it in any dac, putting it in another case just so you can use a low noise power supply is walking *** backwards
Then do I really need to convert I2S SE signal to differential signal just to connect the USB/I2S module with the DAC within 8 inches?

I putting the converter out of the DAC temporary just because of I'm waiting new BIII SE and OTTO, the layout to be rearrange until all module arrived, not walking xxx backwards, please show some respect to DIYer willing to share. I'm post my work progress here just to appreciate to help from Domenico and sharing some of my joy. If not I will not put into plastic box and connector with cost under USD 4 dollar, just don't want to run it nude and damage the converter during the time before the boards arrive.

It's not fun to solder 8 wires each side, I can always put it next to the DAC with just 4 plain wire, but If I made a opening on the aluminium case will be irreversible!!

use one of these for the panel and a short US cable from the panel to amanero. USB is far more robust to distance and has error correction, keep the cable USB as long as you can and get Amanero as close to the dac as possible, its so small you should be able to mount it directly on top of the dac.

haha, look, you want to take it as a lack of respect, thats all you i'm afraid, you are the one personalizing it, its a broad statement, not directed at anyone. its a bad decision, it should be avoided. if thats what you are doing then you are not even doing what I said, so dont be an idiot.

I mentioned a very specific case didnt I? are you doing that? NO, if you were it would be bad priorities, you do know what the phrase means yes? or is it just because it has the wprd *** you are offended? for this phrase it literally translates as coming at a problem from the wrong direction

I am using a 50mhz crystal for the ESS9023, can I use Ian's reclocker board to reclock the I2S? Do I still need to feed the clock to the 9023?

Thanks

May be yes, can have the module mount above the dac to minize the length.

Yep.
Put the psu in another case instead

During my waiting time I'm doing my own experiments to try out USB bus powered, Stabilized DC and battery powered before putting them into DAC case, it's better than let the board sitting in drawer and do nothing, that's my aim.

ahh did you look up the urban dictionary for that phrase? walking *** backwards? there is that meaning too haha but I didnt mean it quite like that

as Telstar says, if you must, put the reg in another case, well unless you are powering 3.3v directly, even using the salas reg sense wiring I wouldnt do that with the reg in another case, but its really not that hard to make a quality reg small enough, put the raw DC supply and transformer in the other case.

use the salas reg with the case floor as the heatsink and put amanero directly on top of the regulator with the dac right next to it, but really unless you are using amanero to clock the dac master clock synchronously there is little point compromising a layout to feed it with a nice reg.

for creative mounting

use some of this
