Hello Volumio lovers and diy enthousiasts.
First of all I would like to thank this community for all the information and ideas that i have found so far but allow me to introduce my challenge, or problem if you will. I am planning to build a network streamer which will be based on Volumio with a build in dac. I already have two raspberry pi’s. A raspberry pi 3 which runs Kodi and a raspberry pi 4 which runs volumio. As for now the 4 has a hifiberry digi+ which is connected to our Jbl soundbar. But I have a beautifull Marantz 1550 which is recently restored. The plan is to connect the new system to that Marantz. So here’s what I really want:
Raspberry 3 with Kodi
Raspberry 4 with volumio
Settop box (for the tv)
Ideally all of the should be in the same case but to begin the is the problem of space. The case can not be bigger than the Marantz, because of how I (read my wife) wants it to look.
The pi4 will be connected to a dac and so far I have limited myself to these choices:
Allo boss2 (which is not in stock and not sure when it will be)
Audiophonics dac1 sabre (in terms of size is the best option)
Topping e30II which will be taken out of the case and put into the case with the rest of the equipment. In terms of connectivity this is my favourite because the pi3 with Kodi has a hifiberry digi+ and that way I can connect the hifiberry toslink out into the e30 toslink in which in its turn goes out into rca. the screen of the e30 is useless in this setup but that doesn’t bother me.
So far the power supply is my main issue. I have two mean well rs-25-5 power supply’s which I can use and will get the job done. But then there’s low noise power supply’s. From what i’ve gathered so far is that those power supply’s will be better for this kind of system and I will also need two. Is it possible to get two of these:
Or something similar and connect those to one toroidal transformer? This way I will save some space. The pi4 is a bit more power hungry than the pi3 so it needs at least 3A and the dac will need power, thru usb, too.
these are options too in which the second has my preference because of the price.
And than there is the settop box for the tv. That needs to find a place in the same case too, still trying to figure out how to power just another extra thing, and that way all the separate components will be in one case. just looks cleaner
At last there is the design. i would really like to have two on/off buttons with a led on the front of the case. For the rpi3 with kodi there is no problem to shut it down completely but the rpi4 volumio i’m not so sure of. as far as i know i will need something like a pimoroni on/off shim.
Or from audiophonics
But than i will need a power supply that delivers at least 7v
I know i am making things difficult for myself and if all fails there is always the possibilety to just build a pi4 + dac streamer/player
Any thoughts, ideas of ruggestions are very welcome.
