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!!

    Switching supplies are much cheaper to manufacture, linear power supplies often sound much better. Much product at the higher price points use linear supplies but there are better and worse quality switching supplies as well. Wal wart styles are the lowest of the low.

    However, at the price points of products that use outboard wal wart style supplies, you’re probably better off saving your money on after market linear PSUs and budgeting to upgrade your equipment instead.
