Currently, I have the PI4 running Volumio into the SMSL-SU8s DAC then into my powered AudioEngine 4 speakers. Mostly running Quboz and DSD files and really good. The only thing that is missing is the speakers are a little flat and at times I need less mid bass and a bit more high end. I have been patiently waiting for the Volumio EQ plug in to come back but who knows how long that will take. So my solution is the external Shiit Loki Mini + four band EQ. It runs about $150.00
Anyone have any experience with external EQ and Volumio or this device? Thoughts?
