I can’t speak from personal experience with Puritan Audio conditioners, but depending upon your budget you might want to check out either their 136 or 156 model. Type in Puritan Audio in the Form search bar for a fairly recent thread on them. Also you can search on Audio Circle under power conditioners. They seem to have a lot of very happy owners. Archon Audio is a dealer that sells them, there may be others (I’m not affiliated, just providing some info).
