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.

I would hazard a guess that when you use it from battery you are not getting all the and RFI from the mains supply.
