Looking to make some upgrades to my home theater system. Currently running 3.1 with NHT Classic 3 bookshelves and a Classic 3 center. With a 20 yr old Panasonic subwoofer. Last year upgraded the tv to a Sony A80K Now looking to upgrade the sub to a SVS PB-2000 Pro and the receiver Room size is 1150 ft^3 with 1/3 of the room open to our kitchen which is the same size. Small condo hence why I’ve stuck with the 3.1 setup so long. Going to be moving to a house in 3-4 months and would like a receiver that has the ability for 5.1.4 or 5.2.4 setup and HDMI 2.1 Budget for the receiver is ~$2000 Thanks for any recommendations
