3 or 4 way phantom gold system

[Ryu79]

I’ve been a very satisfied owner of stereo phantom golds + dialogue for around two years now and just recently picked up a pair of phantom reactors 900,  which I’m also happy about.  However Ive been thinking of upgrading the phantom gold pair to either 3-4 gold phantoms,  ie 1L + 1R + 1C(mixed)...wondering if anyone has this configuration and if so, how does it compare to just a stereo pair of golds.  Hopefully someone can share their experience with this setup.  Thanks
