B&W 805 D4: which 5 channel power amp should I go with (home theater): Parasound or Rotel

Hearing Hans Zimmer score play during scenes from The Dark Knight, Inception & Interstellar is life changing. The 805 D4 works great for l/r speaker for movies. Of course I need to add a center channel which would either be the HTM81 D4 or the HTM82 D4 but I’ll save that for another discussion.

Here are the power amps I’m looking at:

Parasound:

- Halo A 51

- Halo A 52+

Rotel:

- RMB-1585

- RMB-1585MKII

I’m not able to go into an audio store to test out power amps  so I would like your expert opinion on which might work better with these speakers or if you have any recommendations for 5 channel power amp then I would gladly go take a look at those online.

Thank you for your time.
