Well, good question. I have a Marantz 8002 which I was going to use in my family room set up with my 5.1 monitor audio silvers and then use my older (but still excellent B&K AVR507 v.2 in my home theater. It’s a 7 channel 150w into 8Ohms. It has a huge toroidal amp which can sustain high watts of called for without straining. Rebel speakers use Berrilym tweeters also as do the lower end Focal centers at $2,100 new or something of the Monitor Audio centers with CCAM (ceramic coated aluminum magnesium) drivers which I believe have a similar timber. I’m thinking any with dual 6” drivers would match well - in the $1,500 range rather than $4k for the Focal Sopra. Just thinking out loud. I really don’t want don’t want to go with a phantom center bc I’ll always find another use for money!
