Any chance of moving to a receiver and speakers?

2. Receiver: https://www.cnet.com/topics/av-receivers/best-av-receivers/
So the Sony. https://smile.amazon.com/Sony-STRDN1080-Channel-Theater-Receiver/dp/B06XKRWWSG/
That's under 1K even after you get some plugs and wire.
My current one is old as the hills and it cuts in and out and even when it doesn't it sounds terrible. My current system is a Logitech Z-7500
The specs for that are underneath if anyone cares...
