Is a power supply beneficial for component SQ if you have a quality power conditioner?

Thank you whart. I too have a dedicated power line to my audio room, with a 4 plug furutech heavy duty outlet. My power conditioner has 2 seperate runs of receptacles...one set for digital the other for analogue. So I suppose that the wal wart plugged into the power conditioner defeats the purpose?

I don’t know the answer. The noise from the wall wart may be ameliorated by the Shunyata. I had a bunch of Shunyata gear many years ago but can’t answer your question beyond what I’ve done with the linear supply for the wall warts. What was interesting to me, based solely on the read out of the power supply, was how little current the devices themselves- the Schumann generator and the DSP unit- actually draw. The linear supply was under two hundred dollars- you can make the cable yourself using switchcraft barrel plugs and appropriately gauged wire for the voltage and length- I can point you to the one I use. It offers more flexibility and is cheaper than some of the audiophile ones that are built for a single voltage.
I guess in theory, by keeping the wall warts plugged into the standard household electrical branch rather than the dedicated line, you are already isolating them to a degree. I don’t know how much of that digital noise is carried over a common ground, since even your dedicated line ultimately ties into the same grounding point as your main household system.

Interesting. Deserves more looking into. Thank you

I think it depends. Price matters! In the sense that don't overspend for a fix.

I have replaced the wall wart on my Squeezebox Touch and my Mytek Brooklyn (not exactly a wall wart) but to be honest I haven’t found a big difference. Maybe I should go back for a while. :)

I’m not really sure if they help the device perform better, or just reduce the amount of noise they inject back into the AC. Some of this may depend on your other components and which side of the AC conditioner they are on.

I try very hard to keep all network devices and their associated wal-warts "outside" of the power conditioner so any noise they generate will be cleaned before it gets to my preamp/amp/DAC.

Best,

I am quite new at all this, and this is my first higher end audio system. I am trying to accomplish good clean power to my streamer component. I have had built a dedicated electrical power line and purchased a power conditioner (which retails for $2250) in order to provide that good clean power. I am just wondering if the things I have done have supplied the good feed of power that I need and if that is all I need to do, or does a wall wart disrupt what I have done and corrupt the supply of good power to the component. I don't want to purchase a power supply if it is not necessary based on what I have already done....but I don't want to undermine my investment either.
