RE: Dacs powered by batteries - any successful story ?


Hi and thanks for the interesting reply.
yes of course this is a successful story indeed.
I even wonder why batteries are not more popular.
I think that a unit could be made with a switch, for charge and listening modes.
In charge mode the unit is connected to the mains, can be used and charge the battery pack at the same time.
In listening mode the unit is disconnected from the mains and use the power stored in the battery pack.
I am working on a diy project to make something like this for a usb to spdif converter. My feeling is that the stock unit has a power supply of debatable quality. And also the my mains voltage is not clean.
The isolation from the grid that batteries can provide is very tempting.
Actually i am planning to use the type in the link.
I hope two in series would be enough.
This should give me at least complete isolation from the mains.
Thanks a lot for the valuable advice.

Kind regards,
bg
