I think your particular application is more important. Home theater?- get a Chang Lightspeed.2 channel? get the Custom Power Bloc for the front end----only.Then get a good power cord for the amp; then straight into the wall.I do both;and have both.Not to unlike sep. amp and pre amp.One is better for one thing/the other for the other. The Power Block won't help or even work on the tv,but it KILLS the Chang for 2 channel front end application.
