Batteries do wonders

Welcome to the battery club. Music is made of silence, rhythm and tones. We spend lots of time tweaking the tone and forget to tweak for silence.

I suggest that you solder a large (2 to 5 uF) 250 V or 400 V poly cap across the PS entry terminals on your DAC. This will help as a local bypass and will improve DA BASS.
The Cap should have very low dissipation factor (DF). Hovland and Auricap make high-capacitance high-quality plastic film caps.

Also, use shielded, twisted pair cable from the battery to the DAC. CAT 5 cable is pretty good for the job, use both wires of a twisted pair for +, the second pair for -.
The CAT 5 cable shield should be grounded at the DAC chassis end only.
BTW, fuse the battery! A battery has huge current capability, there will be lots of sparks and smoke in case of a short circuit (without a fuse).
good luck
