Since I'm not an electrical engineer, may logic may be flawed, but here's my proposition as it concerns switching vs. linear power supplies, and also choking the power cord with a ferrite core:
My assumption is that whatever noise/coloration/etc. the power supply is going to be adding to music will be evident whether the SqueezeBox is playing music or not, because, well ... the power supply is always supplying power. To compare power supplies, I suggest turning the volume up to max on the SqueezeBox -- not while your playing music, mind you, but while the SqueezeBox is idle. Then, turn the volume of your amp up to max. Now, get a good set of headphones and listen. Even with the quietest system, you'll hear noise. Have your wife or someone switch power supplies, or add and remove the choke from the power line while your listening through the headphones. If you can hear a difference, pick the quieter option. BTW, disconnect your speakers during this experiment. switching power supply sends a big spike through my speakers when I plug it in and unplug it. Also, if you happen the get the White Noise of Death during the experiment, it'll probably kill you on the spot ;-) Comments?
