Thank you Phaelon. I'm going to invest sometime researching some of the pieces that others have had some sucess with. My leanings are toward believing that what will work best is a high quality passive power strip with good wire, connectors, and outlets - that is what I would compare any of these active approaches to them. My sense at this very early stage is that active devices can obviously affect the sound as a tone control might. I get the sense that as such, how good a piece is might be very dependent on the system it is used with. I'm not sure if I'm right, but if I am it really requires more experimenting than I have thought it might. I assume that like other components, active power conditioning and/or filtering will tend toward the musical versus neutral divide - if you know what I mean. My system is on the neutral side with CAT amp, Placette Active pre, and Merlins. I suspect I would need to choose power conditioning the leans towards "relaxation" and "warmth".
