Glad to see so many 7 users in this thread! I have had the 7 for two years and have found that they somehow are more sensitive to powerline quality than other systems that have gone through my place, i.e. my system through the 7 sounds vastly different during different time of the day and it is quite repeatable. Anyone else experience this? It is quite annoying and I wonder if adding something like Audioquest Niagra (8000?) that is said to be made for the 7 will solve this. When the stars align, I feel I am at the pinnacle point of this hobby, but at other times, I wonder what went wrong. Took me some time to figure out its the power.
