I upgraded from the 5100 to the HTPS 7000 and could not be happier. I also have a dedicated line for my system. IMHO having the combination of dedicated lines with power conditioning is the way to go. I have tried my integrated through the power conditioner and directly from the dedicated line and found that I prefered it through the conditioner. The HTPS 7000 uses dual transformers and ballanced power which I feel is a plus.
