Shorter board with all smd - is that possible?

First of all, kudos for the project: IS GREAT.

Second: in your opinion, would be possible to elaborate a pcb that can contain all the parts (shitfters + raspi pico stuff + dac) to solder on, to make it smaller?

Thanks!

Yes, I have designed such a PCB (not tested yet), but I cann tell you that this is nothing for hand soldering: plenty of really small footprint components. Nevertheless, I will continue this path, even if it's just to have it done ;-)

As a middle-ground there will be a PCB with the DAC and OpAmp on board.

That middle-ground board would be nice.

Will look like this and be released together with a (major) firmware upgrade...

Looks very neat!
