• Dolby Atmos, DTS:X Pro, Auro-3D, and IMAX Enhanced immersive formats
• 8K/60Hz and 4K/120Hz passthrough for next-gen video sources
• Advanced room correction and calibration for flawless acoustics

Below are the best high-end home theater processors of 2026, offering studio-quality sound, 8K video switching, and future-proof expandability for serious cinephiles and luxury custom theaters.
