Does anyone know if there is a noticeable difference between the sound quality of using batteries to power your gear vs an AC wall outlet?
If I had to guess, I would say batteries would be better because you avoid the AC -> DC conversion which might otherwise add noise and batteries are completely isolated from other electronics. Whereas, with AC, every single thing plugged in at your house may add interference.
What are your thoughts?
