Questions about Klipsch R-820F

Can we put these speakers at the rear in a 5.1 configuration and have the R-605FA (atmos) at the front?

Can this be connected directly to a record player that has a speaker output, or do I have to do this via an amplifier/receiver?

Have this speaker, ask Marantz 70s (50watt at 8ohm) would it also work, or do I have to take stronger ones?

Hello, I have the Klipsch R-820F. I am very satisfied with these speakers. I think I could get much more out of them. At the moment I have a Pioneer A-616 amplifier. I think that most of the time it's too bass-heavy, even though you turn the bass control way down. Would you have a recommendation for a really cool sound? Thanks for the help.

I have Yamah NS 777 as my front speakers, do you think I should replace them with the Klipsch 820F? Yamaha even after so many years are still expensive then Klipsch.

Good day , can this speaker be connected to an Onkyo TX-NR696 receiver?

What amplifier or receiver would be suitable for these speakers? It has to handle 150 watts and 8 ohms, right?

This R-820F speaker is very similar to the R-28F, is the price difference justified? Thank you for your comments. Bruno
