* A "limited" reference indicates that the given technology has some capability of addressing a gremlin within limits under specific circumstances, or in a way that can not fully mitigate the problem. This chart is based on manufacturer's specifications and product claims, some of which are unsubstantiated.

There are 10 Power gremlins arrayed across the top of our PurePower Comparison Matrix. Each one has its own ability to plague your Audio and Home Theatre system. (See our Gremlins page for details.) Ideally, a perfect power conditioner will stop all ten of them in their tracks. Down the left side we have placed the common technologies used to fight power gremlins, along with an example of a commercial brand of each technology. (If you are curious about which row to place some particular brand or model, and the description offered by the manufacturer provides little clue, drop us an email and we'll be glad to help.) By following along the row, it is easy to see how many gremlins each solution overcomes. In practice, each model of each brand of power conditioner on the AV market uses its technology to either remove - or more often to just reduce or ameliorate - the affects of 1 or 2 or 3 gremlins.

You can also use the Matrix to find a
product type to suit your particular favorite gremlin. For instance, if
you know that your audio system is suffering from RFI interference from
a nearby transmission tower, you can go to the RFI gremlin and run down
the column to see all technologies that will help. If you are lucky, and
you are only subject to one of two gremlins, you can just buy the
specific solution.
Of course, we are fond of pointing out that its a bit difficult to diagnose exactly which gremlins have crept into your power lines - without a $5,000 power quality meter to tell them apart. Just to make gremlin hunting even more sporting, the brownout gremlin you chased away on Thursday morning may be replaced by his cousin harmonics gremlin Friday afternoon. The perfect gremlin free week you experienced in May, will be utterly overrun in July when your neighbors turn on their air conditioners. It is a bit self serving, we admit, but isn't it obvious that the clever solution is to skip all the partial solutions and simply go for the technology that wipes out all gremlins?
