I dont know about Telos technology, but what they do for both audio and video differ from Nordost according to my experience. And I have plenty of every Nordost QRT product, including the new QWave and QSine, and Telos over several years. Also comparing Telos to Add Powr (run by the man behind the Nordost QRT products), they are very different. But IMO they compliment each other very nice.
To others who experiment with one plug in the wall next to the outlet for your conditioner, why not add a power strip and add several and dfferent power plugs. If you have space and funds for it of course.
And, if you are not quite happy with a product in your stereo, before you sell it or return it, try it on your ac line for your refrigerator or freezer. I have found that reducing amount of noise going back to meter board from these devices helps a lot, even with dedicated ac lines for stereo.
