I’ve got a rpi model B setup headless with Arch, connected via 3.5mm to my amplifier’s (Technics SU-VX800) aux connection. I ssh into it and use mocp or pianobar to provide streaming music.
It works passably, no hissing or other distortion, but I have to turn up the volume on a lot higher than I’d like (on the amp) in order to get decent sound. It just feels like it needs more ‘umph’.
Using pure Alsa, and mixer is set at 95%. I’m assuming I need a preamp or similiar between the rpi and the amp, but the question is what. Anyone using a similiar setup? Would an addon soundcard/DAC make any difference?
Thanks for any help.
