Integrated amp for Philharmonic BMR monitors

Wow. I’ve typed a lengthy response twice and it deleted out as I paused…smh. 
short story is I’m looking for nice separation with no fatigue. I appreciate the advice so far. I’d love for some BMR owners to share their experience as well.  
currently living with Sonos 5. Last set up was 

Oppo 105 / ARS Filarmonia / Merlin VSM / 2 JL audio f110s

I ran across the rogue CM3 for 1899$

Great amp but not enough power for the inefficient BMR. 

Given what you’re looking for, this MF A5 is worth a look and certainly has plenty of power and also a review that gives some insight to its sound characteristics…

This Unison Unico 90 would likely sound great, but it’s a little higher priced and and although it has good power it doesn’t have near as much as the A5…

The seller of both offers returns, which is nice.  Just a couple ideas FWIW, and best of luck. 

Update. 
I went with the Rogue Cronus Magnum 3 as I felt the price was worth it. So I’m now  patiently beginning the search for speakers. I have found a few local opportunities in the Houston area to demo a few brands. Actually local is a CM3/ magnepan demo… so for kicks imma see what all the Maggie hype is all about. 
thanks for the advice so far. 
* haven’t given up on BMRs quite yet tho. Lol

Yeah you pretty much gave up on the BMRs when you got the CM3 and probably Maggies too.  There’s a good reason most here recommend choosing speakers first before the amp, and maybe you’ll now find out why.  Good luck.
