I have a home theater that's the best I could do for the budget and space constraints I have, so this may be beyond what you are interested in, or laughable
Main Speakers: five Zaph Audio ZRT custom-made tower speakers. They are a two-way design using exclusively Scan-Speak Revelator drivers, which are to my ears the sweetest dynamic drivers to base a platform off.
Subwoofers: Monolith M-15v2 and M-12v2, located to eliminate nulls in any listening position. Tuned using Multi-Sub Optimizer and REW.
Atmos speakers: four RSL C34e mkii's in the ceiling, mounting inside dynamat enclosures
Amplifier: Yamaha MX-A5200 11-channel amplifier
Receiver (running as a pre-pro): Denon AVR-X4700H
DSP: two MiniDSP DDRC-88D's running Dirac, tuned by myself using Dirac and REW
TV: LG 77" CX
Primary sources: Nvidia Shield Pro, running Plex client connecting to a Synology NAS running Plex server. I rip all my music and Blu Rays to this device for when I want to enjoy uncompressed reference material. Most of the time though I am watching or listening to streamed content.
The sound quality is superb with drivers like the Scans, but the real party trick is the tuning result from the MiniDSP units. It may not be the loudest system I've ever heard, but it's definitely the most reference theater-like.
