Audiophile Switch ?? Outboard Linear Power Supply ? Whats the deal ??

Here we start the series whereby I check out Music computers, streamers , outboard linear power supplies, and all the other stuff that clutter the heck out of the rig. and send my HiFi OCD into orbit.
These things all range from the hundreds to $30K or more. My intent is to weed through the BS and get to the truth. Lets find out how these things stack up , shall we ?
