Looks like decent engineering to me. Nice board design, good shielding, everything looks dimensioned properly. A bit much hot glue, very small analog section. Analog is not my thing though, so that's probably just me.

@janwilmans what about taking a scope to this? An easy way to fix old speakers that are kicked off of Sonos' system is to grab the I2S interface off the http://www.ti.com/lit/ds/symlink/pcm5101a.pdf … and hook it to a RPi. That reuses the DAC, amplifier and speaker logic entirely.

Sure, I'm up for a hw hacking session? If its I2S a scope wont help for long, cause very soon you'll need a datalogger, but those are cheap, so maybe I should get one and we could have a evening hacking session?
