Cleaner music when laptop is on battery vs plugged in


Hi,
My setup is like this : Laptop -> DAC -> Amp -> Speakers.

Recently, I tried playing music on battery (of the laptop) and noticed that the sound is noticeably cleaner and more engaging than when the laptop is plugged in the power outlet.

I don't know if anybody has experienced the same or similar.

If I use the power filter, will I have the same result?
Thank you.

Laptops are notorious as the worst possible devices to use in Computer Audio, for the very reason cited. May I suggest, as a very inexpensive alternative, using a Raspberry Pi computer with a digi+ S/PDIF card, and eliminate the laptop.
