Oh, I see.
Best bang for the buck Separates?
For Preamp, I would say a Marantz pre-pro.
For example, here is a $2K Marantz pre-pro on sale for $1200:

For Amp, I would say Anthem, Parasound, Rotel, Outlaw, ATI.
You are NOT going to notice any significant difference in Sound Quality in DIRECT/BYPASS mode (bypassing all EQ, Room EQ, DSP) when it comes to amps/preamps. Some believe there may be some slight differences, but those slight differences are not worth losing sleep over.
For amp, I would say a 200-300WPC amp is about all you need.
For preamp, the biggest difference will be the types of EQ software.
For example, some people think Anthem's Arc is just right. Some people think Marantz's Audyssey XT32 is just right. Some prefer Dirac, etc.
I personally don't like ANY room correction. I just like the Dynamic EQ from Audyssey that enhances the Bass in my Subwoofer Outputs.
