What the best sound quality in the new 16 channel pre-amp processors?

I’ve been researching buying a new 15/16 Pre-amp Processor. I’m about 50/50 between music and movies, no streaming yet. My current budget is 5k. I’m not against buying used if it’s in good condition and not old. Doesn’t have to be 8k but at least 4k. I’ve always had Denon or Marantz and am looking for something different. The company new choices seem to be:

Emotiva

Anthem

Arcam

Monoprice Monolith 

reviews seem to point to either Anthem or Arcam. Both have different room correction.

im using all external amps. I’ve got  a Sunfire Cinema Signature, B & K 7250’s and a Crestron 7X200, so all 200 plus watts per channel. 

I’m currently using all Klipsch RP 8” floors and I do have six RS-7’s for overheads

I have four subs running too. 
 

it be nice to try them all but you can’t do that. Looked at all the reviews online and YouTube. 
 

Any opinions or feedback would be greatly appreciated 

Thanks Much
