The switchers have fans, I find them noisy.  I have used many Astron linear 
supplies.  I find that if they are located a few feet away from the station 
equipment, on a surface which provides acoustic dampening (like a couple of firm 
mouse pads), or in a  vented enclosure, that I can achieve the desired "Sound 
of Silence."  You might look at some of the principles of audio studio design 
for some more ideas.
