Which AV Receiver?

millercarbon thanks for your input and for tipping the scales the other way and getting me thinking. To be fair to auxinput he helped me setup at my parents place and convinced me to go the integrated preamp/DAC option over AV receiver for my Yamaha studio monitors which are being used for similar scenario as what I’m after now for my own house. 
You made a lot of sense with the quality vs quantity. I am definitely only concerned with quality. If I have to ditch rears and center than so be it. I already have the sub though. Having good sound for movies will benefit my wife and I but having quality sound for music is what I really want (personally). 
So taking into consideration my budget, are you able to recommend some preamp and amp models which I can look into that will bring out the absolute best of my speakers (for my budget)?
Over here in the U.K. where I am it’s difficult finding somewhere which stocks a lot of kit in store for me to listen to so would appreciate the recommendations here. 

Here is a Rotel A12 integrated amp with DAC. 120 wpc. £700 + shipping. Available from UK eBay seller "emlu17-4". Located in Halifax, W.Yorkshire. NEW IN BOX - never used! Silver finish!

Thanks roberjerman.

I am trying not to ask but I’ve just read about the A12 and I’m a little confused.

What does it mean by integrated?
Is there a preamp and DAC built into this amp?
Is 60 watts per channel enough power? Is this suitable to handle/power the RP-8000F towers at 8 ohms?

Are there any downsides to an integrated amp? Applying what millercarbon said above would suggest that there would be reduced quality?

I remember you laher.  You said that you couldn’t use a center channel at all in that situation and wanted a real simple solution which is why I put forth that audio-gd DAC preamp.  You also wanted power monitors and that was the Yamaha studio monitor suggestion.

However, for movie and tv audio, there is going to be a loss of clarity and coherence if you don’t actually have a center channel.  It’s actually harder to hear dialogue clarity in a 2 channel system, but if you don’t care about that, then a 2 channel Integrated will always sound better than an HT receiver for stereo music in your budget.

an “integrated amplifier” just combines a preamp and amplifier into one device.  Sometimes they also have a built in DAC.  That Rotel A12 is an excellent suggestion and hits all your requirements and it has four digital inputs.  However, it’s not actually 120 Watts per channel like robojerman said.  It’s really only 60 watts per channel so it’s kind of lit on the amp side.  That being said, those klipsch are 8 ohm speakers and extremely efficient at 98db, so they shouldn’t be that difficult to drive.   Just keep in mind that you will not be able to get a center channel with this integrated amp direction.

Good memory auxinput, I know you post a lot so that’s very impressive.
Yes that is at my parents place. I am
happy with the setup so thanks again. Just out of curiosity: I’ve removed the sub (Klipsch R-12SW) and that’s going to be used for my setup we are now discussing. So at my parents place is just the Yamaha’s. What would it take to add a center speaker to their setup? Would I need to add in an amp? Or is it better for them to get an AV receiver?

So for my setup, thanks for taking the time to explain what an integrated amp is. Is there no possibility of going this route but allowing for a center in the future? 
As for the Rotel A12’s, should I not be looking for something with more power per channel? What do I need for those Klipsch towers to bring out the best in them? I know you said that 60 watts is sufficient enough but I guess if I’m gonna spend I want to do it right and go for the best I can. Is there any other options which you could recommend?
