Noob, need help please


Hi there,

I have a pair of Klipsch RP-8000F floorstanding speakers. 
I am a little unclear about what I need to complete my setup. 
I want to use these as home theatre speakers when watching off Netflix or Satellite TV, and also as music speakers when playing off Spotify through the TV. 

Do I need a pre-amp and an amp, or just an amp? What does a receiver do?
Do I need a separate DAC too or an amp with built in DAC?

I am a newbie to all of this so willing to learn, please forgive my lack of knowledge.

My budget is max 1k but then I don’t really know what I need to bring out the best in these speakers. When watching movies I like a little warmth but also like some detail. When listening to music I like a lot of bass. 
I need channels to add in a sub (I have Klipsch R-12SW) and a center speaker (yet to buy but probably will get the Klipsch RP-504C) at a later stage. 
If you need more information please let me know. 
Many thanks in advance!

I have posted my question in Home Theatre and had a few suggestions on an AV receiver, however it was mentioned by millercarbon that for better quality I should go the preamp and amp route.

Thanks jrwaudio for the recommendations. Does that preamp have an integrated DAC?

Can anyone else recommend some preamp and amp models that fit within my budget? If you tell me that I need to spend slightly more than that’s okay. It’s not a hard set budget. I don’t know the price ranges for different types of amps. 
For now I will leave the center and rears and just focus on the towers and sub which I already have.

By the way, I’m in the U.K. and where I live the only shop I know doesn’t have that much shop floor, it’s all online now. So it’s very difficult for me to go and listen and compare. I know sound is all personal preference but at the same time you guys are experts in this field so I’m relying on your guidance. 
I believe millercarbon indicated an integrated amplifier if your were to go with a 2-channel.  At your budget and for best sound quality a 2-channel integrated would serve best. There are many late model used ones for sale. 
if you want the best of both worlds some great audio companies make home theater amps
like arcam , parasound or nad but pricier than 1k .usually stereo is better than 5.1 or whatever they do these days(19.8?) just for music.you can't go wrong with marantz or denon for home theater and 1k is great for those get the best you can within your budget. a center speaker is a must for 5.1 .
All good comments above to get you thinking about what is a priority, and to start listening and pick what is best for your budget.

If going the Receiver route, I would make sure that it has pre-outs, then in the upgrade path you could add and amp for two channel listening, amp/s for other channels and then replace the receiver with a pre-amp.
