I have Snakeoil running on a RPi5 8GB with passive case at the moment (sounds great) and need a second inexpensive unit for a different property so thought I would use an x86_64 for comparison to see if that improves things even further. The RPi is running Raspberry Pi OS Lite but I'll use Ubuntu Pro RTK on the miniPC which I understand should change things up regardless.
There's also other units in the A$400-500 range like the Beelink EQR5 Ryzen 5 5650U (16GB RAM, 500GB SSD) but I'm unsure how much it would improve SQ over something like the Minix (plus the fan is a complication).
I'm currently using LMS+Squeezelite on the RPi. Still experimenting with cpuset and RAM Disk.
Grateful for any feedback or advice.
