… Ahh, I read but forgot about it!
Regularly I switch off all components as DVD player, tuner, power amp, switch and now the RasPi by a master-slave power bar. So I will plug the RasPi directly for the next weeks to avoid prolonged charging of the supercap.
… I already disabled wifi. OK, will check the other parameters.
The player was not shipped set to an I2S DAC. Do I have to adjust special settings for the BOSS?
… I heared about this effect, but to be honest: I believe (and verified by myself) all the hokus-pokus about cables, power supply etc. but do not (yet) believe the network thing.
Another fact: My FLAC collection is growing towards 1TB that’s why I have it on a FritzBox with external 3TB HDD.
The big USB sticks are still too expensive (2TB @ 1.300€) only downwards from 256GB @ 65€ are acceptable.
What about a USB-powered HDD? I powered RasPi + BOSS with the original 3A PSU shipped with the player and is said to be suffizient here in the forum.
I’d really like to keep cabeling as smart as possible - the WAF is inversely proportional to the cable-spaghetti-factor . Have a look at the foto.
@pbarna: Thanks for the hints!
