I spent years messing with power conditioners. I tried many different devices, both series filtering and parallel filtering, and multiple different DC blocking solutions as well. Eventually I realized that power conditioning gives gains in some areas but has too many negatives in other areas.
The best power conditioner was not a conditioner but the Nordost QB8 power strip. I did not want to believe it was better than all my other stuff, because it just seemed like an empty overpriced box. But it was.
