Empirical offers Battery Power Source for Off-Ramp products

This battery power supply provides up to 24 hours of play time on clean battery power. It improves the focus and eliminates a layer of power grunge from the sound. If you use it 16 hours, it will be completely recharge after an overnight recharge cycle. It also uses the AC adapter that came with your Off-Ramp or Freeway, so you can switch from battery to AC power at any time. A LED "gas-gauge" indicator shows you how much charge is left in the battery, so you know when you must switch back to the AC adapter and allow the battery to charge.

Does this imply that the power supply has been upgraded from stock to make it less noisy as well?

Thanks!

There is additional filtering in the battery supply, so I guess the answer is yes.

Meaning that when using AC power, it doesn't bypass the battery (i.e. sits in parallel), but feeds the current through the battery?

Thanks!

No, in battery mode, it is strictly battery and AC mode it is only AC.
