NO, NO, NO.... For all of the above reasons. Instead of your amp running through a 6 ft ( ??? ) power cord to the wall, it now has to go another 6 ft courtesy of the preamps' power cord and a low grade outlet on the back of the preamp.
Besides the extra line length and potential to "starve" the amp on peaks or sustained duration notes, the amp will be fighting with the preamp for power via the same initial cord instead of having their own seperate outlets. This can do NOTHING good for sonics.
Leave all of the components on unless you are in "thunder alley" or in an area that is prone to brown-outs or surges. Not only will they last longer, they will sound better. Sean
