(1) My initial experience with power conditioners (Chang in fact) was quite worthwhile. (2) Everything improved even more when I installed dedicated line powering the full chain of AC conditioners & upgrade AC cords, etc. (3) Use caution when running power conditioning equipment "in series". I was advised to do this, but found that putting two Changs in series (the higher-current model was first in line) constrained dynamics & killed the extension of bass & highs as well. It was not at all a good thing at my house, although it worked well in the other guy's rig (he claimed --- I never heard it myself). I would tend to try the juice bar first if you simply want more outlets; of course you should experiment with various configurations to determine what works best in your rig, because as always YMMV.
