TWO POWER CONDITIONERS FROM THE SAME WALL OUTLET

I have two power conditioners and would like to use the Power Block + Titan for the videos and HTPC (hate to plug the PC into the same line, don't you too?) For the BPT, I am only using it for the audio system which is for critical listening. My Tice user manual said not to plug anything other power conditioners within the same circuit... I would like to know if there is any advantages / disadvantages plugging two power conditioners into the same wall outlet? Does HTPC power supply ruin the power quality within the same power line, what to do to solve the problem? I want to have everything protected, I am confused of what to do... Your feedback will be appreciated.
