Recommended receiver for 6.1 in-wall?


New to the forum, new to Polk and new to audio in general.
I’ve just bought a decent bunch of Polk speakers: front 2x265-LS, ceiling 2x 65-RT, back 2x 65 RT.. for now the SUB is a 12" wireless JBL of some sort..
My question however is: what receiver is recommended for these? I need it for watching movies with atmos, and streaming epic music through my phone.. :)
