Which preamp tubes in my amp make the most difference when rolling?

I have a Primaluna Dialogue Premium HP Integrated? It has 6 tubes in the preamp stage. Here’s a link:

For the small tubes the tubes that make the biggest difference is the center two tubes. But it all depends on what you are hearing now and what you want to hear, tht is you need to have a sonic goal in mind before you start rolling tubes.
