Just put them near the equipment. The ERS cloth has a fairly large effect on some DACs if placed on top of or next to the DAC's power cord. The plate (recommended only as a cheap experiment unless you don't mind looking at it) could rest on top of the player.The idea is to provide materials that absorb and dissipate RF energy. Most materials, like metal cases, reflect RF and insulators allow it to pass through. RF is generated in audio equipment power supplies by the rectifiers, by the digital circuits, and can be carried in on the AC power line. To avoid wasting a lot of time and spending a lot of money on fancy power cords, filters, conditioners, etc., these suggested absorbers give you a quick way to see if there is a specific place in your system where RF is causing trouble.
In my experience at a friend's house, the ERS cloth was very potent, and simply placing it on the transport killed the life in the sound. It had to be moved away quite a bit to reduce its effect.
In my experience with the microwave browning plate, letting it rest directly on top of the CD player did too much. I had to put some books under it to space it away from the player. I found I could dial-in the degree of harshness removal by using different thicknesses of books.
Experiment with these things, and then worry about power conditioners, etc, depending on what you find.
One more cheap way to locate RF is to use a portable AM radio and tune between stations with the radio near different areas of your system. I found my CD player's fluorescent display was making a lot of hash, so I've learned to switch it off when listening.
