Thanks guys !

I recently bought a home cinema bundle and a receiver. I am in the beginning so if I look confused , I am. My setup is: 2 Klipsch Reference RP-8000F II 1 Klipsch Reference RP-504C II 2 Klipsch Reference RP-502S II 2 Klipsch Reference RP-500SA II 1 Klipsch Reference SPL-120 Denon X3800H In this setup I am going to add 2 Klipsch Reference RP-500SA II for my rear up Dolby Atmos speakers 2 Klipsch R 50 M for my rear surrounds So from what I heard the Denon X3800H needs a preamp to be able to run the 7.1.4 setup that I have I plan on using the preamp for the Klipsch Reference RP-8000F II since they are the biggest bois but since I have no idea what to buy, I am a little confused. Can I use the Yamaha A-S s301 as a preamp for the RP-8000F II? I am guessing that it can connect to the x3800h? It says this is a stereo Amp, but I don't think that matters since it goes back in the receiver. And are there any cheaper alternatives? The S301 is about 350 euros in my area so it's quite pricy just to run 2 more speakers so I was looking for something cheaper and maybe not as big of a box. Again, I don't know what I am searching for so maybe this is the thing to buy. And if this is my only option, could someone give me some tips how to connect it? I know I have to connect the speakers with banana plugs but ... It has A or B And A+B modes, then high and low settings and I don't know which RCA port to use. Thank you!
