Have been reading around the Hiraga le Monstre this last week, and having also owned a battery DAC for some time, I got to wondering about this:
Is it possible to design a battery PS for a 25W Class A power amp?
My battery DAC is continuously ‘trickle-charged’ from mains and the battery itself supplies power to the DAC board.
The DAC runs happily all day and as long as it’s switched off overnight there are no issues.
Could a setup like that be scaled up? How big - physically - would it need to be?
