I’m looking for sound quality along with 8k 2.1 hdmi
or 4k with being able to upgrade to 8k
You could try looking into these two items:
NAD Masters M17 V2i (much lower price than your budget, but will likely have an 8K upgrade module in the future).
Theta Casablanca V - very expensive, but also will likely have an 8k upgrade in the future.
The problem here is wanting to be on the bleeding edge of technology but also expecting sound quality.
