I also use a Monster HTS-2000 conditioner with good results in an apartment in LA. It only improves the sound in my setup. I am considering running a second one in series off of the digital power outlet of the first. I would plug my amp into the first one (in the "amp" outlet) and then run the digital gear from the second conditioner plugged into the appropriate digital outlets. If it does not further improve the sound I still have a use for it with our mini system (that needs a conditioner as well). I am also considering the Vansevers Unlimiter that Sedond is trying out, for the amp in our main system. I am afraid to run the gear (amp) unprotected (straight into the wall) due to the power situation in CA. I have tried zip strips from RS that are supposed to be designed for audio as well as various industrial extension cords and they all screw up the sound in my setup.
