I plugged my amp straight into the wall. The rest into the strip.
I immediately noticed a much more open airy sound.
I live in the land of dirty current of the 5 boroughs of nyc. Obviously components, synergy, and location determines if a Power conditioner is necessary.
Shindo makes a nice power conditioner for under 300 usd. If I had to try another one. That would be my choice
best luck
