There's only one person in the Asylum that I know of who can actually hear RFI and that is Todd Krieger :-). What stand-alone hi-fi kit are you talking about that has poor power supply components? Power supplies are designed for the task at hand and oftentimes an overkill power supply offers no benefit."Any decent hi-fi should be designed so that mains-borne noise, RFI, etc is kept at bay "
And any pricey audiophile product plugged into the AC mains should be immune from mains-borne noise via filtering at the AC input to the unit as well as filtering and noise rejection within its own internal power supply.
As an aside there are a number of 'high-end' amps and preamps that use switching power supplies (gasp!) - including your M33 - yet their measured noise is lower than some others with massive linear power supplies. Go figure. Audiophiles will kick and scream that switching power supplies have no place in high-end audio..... but many audiophiles are so hung up on what they learned 50 years ago they can't seem to grasp anything modern.
Some people equate their less than stellar switching power supply experiences with wall wart battery chargers for phones and tablets. They then conclude that all switching power supplies have no place in high-end audio. Silly.
I had a Mac Mini with switching power supply that I swapped out for a hefty linear power supply. It didn't make much difference because the Mac Mini isn't really an 'audio component' even when used as a music server. The actual audio component (including analog circuitry) starts with the outboard DAC. I'm not too concerned - besides, I can't 'hear' RFI like Todd can ;-)
The black object is the Mac Mini's internal switching power supply.
It was replaced by the white filter bank that accepts external 12-VDC.Powering the Mini with the TeraDak 12V 10A Linear Power supply.
Powering the Mini with the 12V 20A Linear Power supply.
Powering the Mac Mini with a 12V battery.
I'm back to running a Mac Mini with its own internal switching power supply because my imagination isn't wild enough to notice the difference.
