Second prototype is finished and is working just fine:
It draws 69.7mA when optical in is used, but that can be reduced by another 12mA by using another optical receiver (which I still don't have).
At any rate, >20hours on 6 NiMH batteries is satisfied even now (and it could be closer to 30 hours with less power hungry receiver) so I can say mission accomplished. I can now work on optimizing the analog stage to sound even better, do opamp rolling etc.
(Edited for better closeup)
