Sabai, Now that I think about it , I guess I am daising chaining a little too.
I have 3 dedicated lines with an Audience aR2p-To on each. But, I also have a Nordost QV2 plugged into each line at the wall. I am also using a MIT super duplex outlet for my Video and that is plugged into my DIY power strip that comes from my Audience power cell.
My experience with an Isolation transformer included a humm that eventually made me sell it.
I will someday try a power regenerator. I was going to order a PurePower unit until I started reading all the bad press against that company.
