Need for Power Conditioning??

The issue is getting clean power from the pole. I am not sure what this Equtech power system is, but unless it is a filter and conditioner, then you can benefit from having such a device chose to your components. The reason being that you are not getting clean power from the pole. You are sharing those power lines with all your neighbors, and with all the machinery within your own house. Air conditioning, refrigerators, and especially computerized equipment makes a lot of noise on the line. When they cut on and off it creates large spikes in voltage, up and down, there are just thousands of noise an spike causing devices between you and he power company. So it becomes necessary to use a filter or conditioner to convert that noisy electricity into something you would want to feed your stereo. If you know an electrician that has one of those hand held oscilloscopes, he can easily show you all of the noise that is coming in off the pole, and depending on where you live it can be quite shocking (pun intended) to see all the noise coming into your house, and being created therein.

To get a preliminary idea how less contaminated electricity "sounds" in your system, try inexpensive Machina Dynamica Flying Saucers for insertion into the unused AC wall sockets of your listening room and other rooms.
Together with Mapleshade Records power strip/power conditioner there is clearly audible improvement or optimizing of system performance, even without pursuing more expensive and extensive fixes.
For me, this is a major contribution to what is needed.
