Legacy Calibre vs Triad Gold or Roon Music Steamer

I have a Triad 5.1 system in area is less than perfect. It is an older home with the large oak opening from dinning room. The opening is almost impossible to get correct phasing. There is a new audio/video installer who recommended replacing the Triad Golds with Legacy Calibre speakers: https://legacyaudio.com/products/view/calibre/ on stands. He feels it will give me the sound/phasing I want. Golds: https://www.triadspeakers.com/products/home-cinema/inroom/ir-gold-lcr/
OR

I am also thinking about looking at the many Roon ready music streamers: https://kb.roonlabs.com/Roon_partner_programs

Main music source is ROON via my PC /NAS via Ethernet into an endpoint. Yamaha/AV Pre amp CX-A5100.

Have an Opppo Blu Ray without Roon.

Thank You Kindly,
