A Christmas Upgrade Advice-- AV Receiver- Please

[Greatestboss]

Hey everyone, I would highly appreciate your advice on upgrading my A/V Receiver as a Christmas Gift to myself

Current Setup:

1. AV Receiver Onkyo TX-NR3030
2. Panasonic DP-UB9000- 4K Player
3. Denon DBT-3313UDCI - Blu-ray player
4. Fronts: Paradigm Prestige 85F
5. Center Paradigm Prestige 55C
6. Surround: Definitive BPVX Powered
7. Back Surround Definitive BPX
8. 2 Pairs of Atmos Speakers SVS Prime Elevation Speaker placed on top of the fronts and surrounds,
9. Subwoofer Definitive Technology SuperCube I
10. Sony 85" TV Bravia 9
11. Room Size 16 Feet X 15 Feet

My interests 4K Movies, Documentaries (Physical Discs Collection of 1,200 Discs), Football+ Sports 85% and Streaming 10%, Music 5% (CD's & Records)

I really like the Marantz Cinema 30 and I was wondering if replacing my 10+ years old Onkyo will make a difference. Any other recommendations are highly appreciated.

Happy Holidays
