I've been using a Raspi as my source for a while now. Had a DAC HAT earlier, then got a Allo digione. Then added a Soekris. The Bahringer DEQ2496 made it's entry a bit later, all of which is to say that I ended up with a medley of boxes and wires - which made sense only to me. Zero WAF, to be honest, it was zero Anybody Acceptance Factor.
So, earlier this year, I decided to put everything into a cabinet. In addition, had seen some streaming source solutions, and thought their LCD screens displaying album art looked very attractive. I think there are special albums released with amazing album art just to make these products look good......
So here is all that needed to fit into the cabinet:
I also wanted to be able to shutdown the RPi gracefully when the front panel power switch was pressed. So I incorporated a delay circuit that maintains power to the RPi for 1 1/2 minutes, when power to the rest of the boards are turned off - the loss of power also triggers a GPIO shutdown in the Pi.
The Pi runs picoreplayer + LMS + squeezelite + jivelite. LCD is Waveshare 5" touchscreen.

So here is all that needed to fit into the cabinet:
- Raspi + Allo digione
- Soekris R2R DAC
- Soekris I/O board (Normunds) with source selector and LED indicators
- PGA2311 volume control board with analog input selector and volume control
- 1 power supply for the analog board (just transformer)
- 1 power supply for the Soekris (DiyInHK)
- 1 power supply for the Raspi+Soekris I/O board + LCD (Sigma 11)

Nice build!! For an even cleaner signal path I would take out the Behringer and replace it with Volumio running in the RPi. Now you could also remove the analog volume and replace it with Volumio (or DAM or CamillaDSP). With Volumio you get CamillaDSP, a far more transparent and competent solution to EQ etc than the DEQ2496. And its is an easy load for RPi. But I'm sure your current state sounds very nice also.

Hi, thks 🙂
I tried volumio, but it's very slow. And I like the LMS material interface and all the flexibility picoreplayer+lmss+squeezelite gives.
The analog volume control could also replaced by the digital volume control in the soekris. But I needed a couple of analog inputs.
But I'll check out Camilla dsp. Haven't so far.
