Hi, one more phono stage post sorry! Can someone please explain the sonic benefits to adding an outboard “linear power supply” box for a phono stage, instead of just using the regular old AC/DC converter that the phono stage comes with? I’m referring to something like this, which would be a standalone unit just for powering the phono stage instead of using the internal, ‘one box’ stock option

How would the sound quality improve? Is it a super noticeable difference?

Thanks!!

    A power supply only has a “sound” if you are hearing hum. A phono preamp needs only a tiny amount of power to function and any power source with reasonable filtering will be fine. If you want to be a purist, set up your phono preamp to be powered by batteries.
