How many power supply devices do I need?

So I have a chord dac, and a roon nucleus, a panaflex power conditioner, an avr and an amp.

It's a "Panamax" power conditioner. Is it something like this...

Plug all your components into the Panamax, then Panamax into the wall receptacle.
No extra device needed between Roon and Dac.

Panaflex power conditioner functions like a linear power supply?

I think you’re talking about a Panamax. Panaflex is a motion picture camera.
A power conditioner is not like a linear power supply, it filters and cleans the dirty power and grunge coming into your house. Most of them also have surge protection

Plug your components into the power conditioner to reduce noise from the electrical system in the house. It does not power your components.

What really gets me is all this effort trying to squeeze a tiny little bit from the wrong ideas about power when in the end it all goes into a..... avr.

MC, you know that and I know that.

OP: what amp, AVR, and speakers do you have?
