My best results are with LC power supplies. Then smaller caps can sound really like...NOTHING.

The smallest sonic footprint of any power supply that I have built has been this way.

Does a battery supply solve any of these problems?
When Chord decided to do a desktop version of their Hugo DAC, I think they retained the battery supply?

Not so much as you still have the problem of finding a battery chemistry that produces the correct voltage or you are adding a regulator to the output, and you still have the charging and discharge voltage variation. Nothing that a battery supplying a regulator doesn't solve, but a transformer supplying a regulator does the same job (though maybe not with as much of a marketing win).

Now try shunt-regulated !
