I’m the process of setting up a new Pi for Volumio. Trying to keep up with my addiction of buying vintage amps!
Currently, I have a 3B+ and regular 3 with a DAC on each and I have not noticed any difference in performance. The 3B+ has 1.4GHz CPU v’s the 3 with 1.2GHz. They both have 1GB of ram.
These are both running in Hifiberry cases so all is well. For the new build I’ve made a custom case with a touchscreen mounted on the front.
Things are getting a bit tight in there with a 3 size model so when I spotted the 3 A+ (which has the dimensions of a Pi 1A+) I thought it could be a good candidate. It has the same 1.4GHz CPU as the 3B+ but only 512 MB of ram.
Only other difference I can see is that there is only 1 USB (instead of 4) and no ethernet. I can totally live with that. Will never use ethernet and never fit more than one usb device (mostly never use usb). Here’s a comparison of all Pis (tip you can remove the cols you do not need).
I use my Volumio/pis to mainly play internet radio and occasionally I stream apple music to it. I don’t have a library stored on a NAS or anything.
So I guess the question is, will things run fine with 512 MB of ram bearing in mind it will be running the Touch screen plugin but not browsing libraries of music?
