@navyachts keep in mind few things -
1. you do have analog gear - your preamp and amp (I wouldn’t connect amp to power conditioner though)
2. The power cable connecting the power conditioner to the wall should be equal or better quality than the power cables connecting connecting your components to the power conditioner.
3. I would recommend Audioquest power cable for the Audioquest power conditioner.
Just a side note - I ran a dedicated line for my system and stopped using power conditioners. I just use the best possible power cables and outlets. Not saying that’s the best approach but it works for me.
